Description

Technical Field

[0001] This application relates to the field of electrical digital data processing technology, and in particular to methods, apparatus, equipment, storage media and products for generating power distribution schemes. Background Technology

[0002] In industrial power distribution design, generating a reasonable power distribution scheme can improve the load factor of the power system. Traditional methods of generating power distribution schemes mainly rely on designers' experience. However, this approach often results in schemes that do not match actual operating conditions and fail to meet the reliability requirements of the power system. Summary of the Invention

[0003] The main objective of this application is to provide a method, apparatus, equipment, storage medium, and product for generating power distribution schemes, aiming to solve the technical problem that the power distribution schemes generated by traditional power distribution scheme generation methods do not match the actual operating conditions and are difficult to meet the reliability requirements of power systems.

[0004] To achieve the above objectives, this application proposes a method for generating a power distribution scheme, comprising: obtaining power distribution demand information of a target process, wherein the power distribution demand information includes the total installed capacity of the target process and the equipment type of the electrical equipment required by the target process; determining the bus configuration scheme corresponding to the target process based on the power distribution demand information; and outputting the bus configuration scheme corresponding to the target process, wherein the power distribution scheme includes the bus configuration scheme.

[0005] In this embodiment, since different total installed capacity corresponds to different bus current carrying capacity and different equipment types have different requirements for bus stability, the total installed capacity of the target process and the equipment type of the electrical equipment required for the target process can comprehensively reflect the actual working conditions of the target process, so that the final generated bus configuration scheme can match the actual working conditions and improve the reliability of the power system.

[0006] In one embodiment, determining the bus configuration scheme corresponding to the target process based on power distribution demand information includes: obtaining the electrical characteristic parameters of historical projects for the corresponding equipment type; and determining the bus configuration scheme corresponding to the target process based on the electrical characteristic parameters of the historical projects and the total installed power of the target process.

[0007] In this embodiment, the bus configuration scheme corresponding to the target process is determined based on the electrical characteristic parameters of historical projects for the equipment type and the total installed power of the target process. During the generation of the bus configuration scheme using this system, the electrical characteristic parameters of historical projects corresponding to the equipment type are combined to ensure the scheme fits the actual operating scenario and reduces adaptation deviations. By associating the total installed power, the system ensures that the bus load-bearing capacity matches the actual demand, avoiding overload or resource waste. Furthermore, by jointly determining the bus configuration scheme corresponding to the target process using the electrical characteristic parameters of historical projects for the equipment type and the total installed power, the accuracy of the generated bus configuration scheme is improved.

[0008] In one embodiment, determining the bus configuration scheme corresponding to the target process based on the electrical characteristic parameters of historical projects and the total installed power of the target process includes: estimating the electrical characteristic parameters of the target process based on the electrical characteristic parameters of historical projects; correcting the total installed power of the target process based on the electrical characteristic parameters of the target process to obtain the target total installed power; and determining the bus configuration scheme corresponding to the target process based on the target total installed power.

[0009] In this embodiment, based on the equipment type of the electrical equipment required in the target process, the electrical characteristic parameters of historical projects corresponding to the equipment type are obtained; based on the electrical characteristic parameters of the historical projects, the electrical characteristic parameters of the target process are estimated; based on the electrical characteristic parameters of the target process, the total installed power of the target process is corrected. Finally, the bus configuration scheme determination module determines the bus configuration scheme corresponding to the target process based on the target total installed power. Since different equipment types have different electrical characteristics, the electrical characteristic parameters of historical projects provide electrical references for different equipment, ensuring the accuracy of the electrical characteristic parameters of the target process. On this basis, the total installed power of the target process is corrected based on the electrical characteristic parameters of the target process. The corrected total installed power is closer to the actual operating conditions of the target process, breaking the limitation of the traditional one-size-fits-all selection based on rated installed power. By determining the bus parameters through the corrected target total installed power, the problem of excessively high bus parameters is effectively avoided, thereby improving the reliability of the power system.

[0010] In one embodiment, correcting the total installed power of the target process based on its electrical characteristic parameters to obtain the target total installed power includes: calculating a comprehensive correction coefficient for the total installed power of the target process based on its electrical characteristic parameters, wherein the electrical characteristic parameters of the target process include the standard total utilization factor, the effective number of standard electrical equipment, and the standard historical total installed power; and calculating the target total installed power based on the comprehensive correction coefficient and the total installed power of the target process.

[0011] In this embodiment, the comprehensive correction coefficient calculation module calculates the comprehensive correction coefficient, and the target total installed power calculation module uses the comprehensive correction coefficient to correct the total installed power of the target process. This not only accurately reflects the actual power demand of the equipment, but also reasonably assesses the overall impact of the equipment on the total installed power, making the target total installed power more consistent with the actual working conditions and more accurate.

[0012] In one embodiment, determining the bus configuration scheme corresponding to the target process based on the target total installed power includes: calculating the bus current required for the target process based on the target total installed power; and determining the bus configuration scheme corresponding to the target process based on the bus current.

[0013] In this embodiment, the bus current required for the target process is calculated by correcting the target total installed power, and then the bus configuration scheme suitable for the target process is determined based on the bus current, thereby improving the accuracy of bus selection.

[0014] In one embodiment, the power distribution demand information also includes electrical characteristic parameters of non-production equipment, and the power distribution scheme also includes a transformer configuration scheme; after outputting the bus configuration scheme corresponding to the target process, the scheme further includes: determining the transformer configuration scheme based on the bus configuration scheme and electrical characteristic parameters of non-production equipment corresponding to each target process; and outputting the transformer configuration scheme.

[0015] In this embodiment, after generating the bus configuration scheme, a transformer configuration scheme is generated based on the bus configuration scheme corresponding to each target process and the electrical characteristic parameters of non-production equipment; the transformer configuration scheme is then output. During the generation of the transformer configuration scheme, the electrical characteristic parameters of the implicit load, non-production equipment, are considered. The generated transformer configuration scheme is no longer based solely on empirical estimation but is more closely aligned with actual operating conditions, thus improving the reliability of the power system.

[0016] In one embodiment, determining the transformer configuration scheme based on the bus configuration scheme and electrical characteristic parameters of non-production equipment corresponding to each target process includes: obtaining the electrical characteristic parameters of the bus in the corresponding target process based on the bus configuration scheme; calculating the apparent power of the transformer based on the electrical characteristic parameters of the bus and the electrical characteristic parameters of non-production equipment; and determining the transformer configuration scheme based on the apparent power of the transformer.

[0017] In this embodiment of the application, in the process of calculating the apparent power of the transformer, not only are the electrical characteristic parameters of the explicit loads such as the busbars in each production process taken into account, but also the electrical characteristic parameters of the implicit loads such as non-production equipment are taken into account. The calculation of the apparent power of the transformer is no longer just based on empirical estimation, but is more in line with the actual operating conditions, thereby improving the reliability of the power system.

[0018] In one embodiment, calculating the apparent power of a transformer based on the electrical characteristic parameters of the busbar and the electrical characteristic parameters of non-production equipment includes: determining a transformer simultaneity factor based on the electrical characteristic parameters of the busbar and the electrical characteristic parameters of non-production equipment; correcting the target total installed power of the busbar using the transformer simultaneity factor, and correcting the total installed power of non-production equipment using a preset non-production equipment demand factor; and calculating the apparent power of the transformer based on the target total installed power corrected for the busbar and the total installed power corrected for non-production equipment.

[0019] In this embodiment, the transformer simultaneity factor reflects the probability that both production and non-production equipment connected to the busbar will simultaneously reach maximum power. This factor can be determined more accurately by analyzing the electrical characteristic parameters of the busbar and non-production equipment. Similarly, the preset non-production equipment demand factor considers the simultaneous use of non-production equipment in actual operation, and the corrected total installed power of non-production equipment is closer to reality. Calculating the apparent power of the transformer based on these two corrected power values ​​allows for an accurate assessment of the transformer's load capacity in actual operation. This avoids errors caused by evaluating transformer load capacity solely based on total installed power. Overestimating the load capacity may lead to selecting a transformer with insufficient capacity, resulting in overload operation during peak load periods, affecting equipment lifespan, and even causing safety accidents. Underestimating the load capacity and selecting a transformer with excessive capacity will result in resource waste and increased investment. Accurate load capacity assessment provides a reliable basis for subsequent transformer selection.

[0020] In one embodiment, the electrical characteristic parameters of the busbar include a first maximum coefficient and a target total installed power, and the electrical characteristic parameters of the non-production equipment include a second maximum coefficient and a total installed power. Determining the transformer simultaneity coefficient based on the electrical characteristic parameters of the busbar and the non-production equipment includes: determining the target electrical characteristic parameters based on the target total installed power of the busbar, the first maximum coefficient, the total installed power of the non-production equipment, and the second maximum coefficient, wherein the target electrical characteristic parameters comprehensively reflect the different power characteristics of all production and non-production equipment; and determining the transformer simultaneity coefficient based on the target electrical characteristic parameters.

[0021] In this embodiment, target electrical characteristic parameters that can characterize the power characteristics of all production and non-production equipment are obtained by using the target total installed power of the bus, a first maximum coefficient, the total installed power of non-production equipment, and a second maximum coefficient. Based on these target electrical characteristic parameters, the transformer simultaneity factor is determined, so that the calculation of the transformer simultaneity factor is no longer simply based on the rated power, thus improving the accuracy of the calculation results.

[0022] In one embodiment, the power distribution demand information also includes the process type of the target process, and the power distribution scheme also includes a power distribution equipment configuration scheme; while generating the bus configuration scheme, the method for generating the power distribution scheme also includes: determining the target power of the target process based on the process type of the target process and the equipment type of the electrical equipment required by the target process; and determining the power distribution equipment configuration scheme corresponding to the target process based on the target power.

[0023] In this embodiment of the application, since different process types and different equipment types correspond to different operating scenarios, the target power and power distribution equipment configuration scheme required for the target process can be determined for different operating scenarios. This differentiated processing method based on different process types and equipment types enables the determined power distribution equipment configuration scheme to accurately match the actual operating conditions and improve the reliability of the power system.

[0024] In one embodiment, determining the target power of the target process based on the process type and the equipment type of the electrical equipment required by the target process includes: determining the target power of the target process based on the power distribution design parameters determined by the process type and equipment type, wherein the process type includes production processes and non-production processes, and the equipment type includes production equipment and non-production equipment.

[0025] In this embodiment, the process type of the target process and the equipment type of the electrical equipment required by the target process are obtained. Based on the power distribution design parameters determined by the process type and equipment type, the target power required by the target process is determined. Finally, based on the target power, the power distribution equipment parameters adapted to the target process are determined. Since the power distribution design parameters corresponding to different process types and different equipment types are different, the above method can adapt to the calculation requirements of target power under different operating conditions, making the calculated target power more accurate.

[0026] In one embodiment, determining the power distribution equipment configuration scheme corresponding to the target process based on the target power includes: calculating the required current of the target process based on the target power, a preset power factor, and a preset load rate; and determining the power distribution equipment configuration scheme corresponding to the target process based on the required current of the target process.

[0027] In this embodiment, the required current for the target process is calculated based on the target power, preset power factor, and preset load rate. Based on the required current of the target process, the parameters of the power distribution equipment adapted to the target process are determined. Since the required current is calculated based on the determined target power, combined with the preset power factor and preset load rate, the current calculation closely matches the actual operating characteristics of the equipment. This avoids both under-matching leading to overload of the power distribution equipment and over-matching causing waste of equipment and costs.

[0028] In one embodiment, the power distribution scheme further includes a cable configuration scheme; after determining the power distribution equipment configuration scheme corresponding to the target process based on the target power, the scheme further includes: determining the cable configuration scheme corresponding to the target process based on the power distribution equipment configuration scheme and the target process; and outputting the cable configuration scheme corresponding to the target process.

[0029] In this embodiment of the application, after determining the power distribution equipment configuration scheme, a cable configuration scheme adapted to the target process is determined based on the target process and the power distribution equipment configuration scheme adapted to the target process, so as to meet the generation requirements of cable configuration scheme under different working conditions and make the generated cable configuration scheme adapted to the actual working conditions.

[0040] In the industrial sector, electricity is the core energy source driving various production equipment, and its stable and efficient supply is crucial for ensuring the continuity of industrial production and product quality. Industrial power distribution design, as a key component of power system construction, aims to rationally plan power allocation to ensure that different production stages receive the corresponding power support. Among these aspects, the generation of a scientifically sound power distribution scheme is of paramount importance, as it directly relates to the power system's load factor, thereby affecting the efficiency and cost of the entire industrial production process.

[0041] In the traditional model, the generation of industrial power distribution schemes mainly relies on power distribution designers to manually estimate power distribution parameters based on their own experience and professional knowledge, and then generate power distribution schemes.

[0042] However, different target processes correspond to different operating conditions. This method of generating power distribution schemes based on experience often fails to accurately reflect the actual load conditions during operation, resulting in a mismatch between the generated power distribution schemes and the actual operating conditions, which seriously affects the reliability of the power system.

[0043] Based on the above, this application proposes a method for generating a power distribution scheme. The system mainly includes: acquiring power distribution demand information of a target process, wherein the power distribution demand information includes the total installed capacity of the target process and the equipment type of the electrical equipment required by the target process; determining the bus configuration scheme corresponding to the target process based on the power distribution demand information; and outputting the bus configuration scheme corresponding to the target process, wherein the power distribution scheme includes the bus configuration scheme.

[0044] In this embodiment, since different total installed capacity corresponds to different bus current carrying capacity and different equipment types have different requirements for bus stability, the total installed capacity of the target process and the equipment type of the electrical equipment required for the target process can comprehensively reflect the actual working conditions of the target process, so that the final generated bus configuration scheme can match the actual working conditions and improve the reliability of the power system.

[0045] Based on the above, this application provides a method for generating a power distribution scheme, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the power distribution scheme generation method of this application. In this embodiment, the power distribution scheme generation method includes: Step S10: Obtain the power distribution demand information of the target process, wherein the power distribution demand information includes the total installed capacity of the target process and the equipment type of the electrical equipment required by the target process.

[0046] It should be noted that there are different procedures involved in designing the power system of a new energy plant, and each procedure has different circumstances, resulting in different busbar selection methods.

[0047] The target process can be any production process related to product manufacturing during battery production. These production processes can include battery stirring, cold pressing, die-cutting, assembly, and baking. The stirring process involves mixing positive / negative electrode active materials, conductive agents, binders, and solvents to prepare a uniform electrode slurry. The cold pressing process involves pressing the coated electrode sheets at room temperature to increase material density, reduce thickness, and enhance conductivity. The die-cutting process involves precisely cutting the cold-pressed electrode sheets and separator to the battery dimensions to ensure assembly accuracy. The assembly process involves stacking / winding the positive electrode sheets, separator, and negative electrode sheets, and assembling them with the electrolyte and casing to form a battery pack / finished battery. The baking process involves baking the electrode sheets, separator, and casing at high temperatures to remove moisture and impurities, preventing internal gas generation and short circuits. In addition to the processes mentioned above, the production processes in this application can also be other processes in battery manufacturing, such as battery formation, capacity building, or sorting processes, without specific limitations.

[0048] Among these, power distribution demand information refers to the various requirements and parameters of the target process for power supply. This information forms the basis for generating the bus configuration plan. Power distribution demand information includes the total installed capacity of the target process and the types of electrical equipment required by the target process. This power distribution demand information can be uploaded by power distribution personnel.

[0049] The total installed capacity of the target process mentioned above refers to the maximum theoretical output capacity of the entire power system under ideal conditions. The total installed capacity of the target process is the sum of the rated power of all electrical equipment under the target process. If the rated power of each electrical device under the target process is the same, then the total installed capacity of the target process = the total number of devices. Rated power of a single device.

[0050] The target process may involve multiple electrical devices, each of different types. The target process is executed by at least some of these devices, which may perform the same or different processing flows within that process; this application does not impose any limitations on this. For example, for the mixing process, the electrical devices may be electrode slurry mixing tanks, batching pumps, dispersers, etc. For the cold pressing process, the electrical devices may be electrode cold pressing machines, tension control roller motors, conveyor belt motors, etc. For the die-cutting process, the electrical devices may be electrode die-cutting machines, feeding motors, waste recycling motors, etc. For the assembly process, the electrical devices may be stacking / winding machines, electrolyte injection pumps, core packaging machines, etc. For the baking process, the electrical devices may be vacuum baking ovens, vacuum pumps, temperature circulating fans, etc.

[0051] It should be noted that each target process has different power distribution requirements and busbar selection methods due to variations in the type or quantity of electrical equipment required and the total installed capacity. Therefore, different power distribution requirements exist for different target processes to adapt to their actual operating conditions. This allows each target process to select the appropriate busbar configuration based on its power distribution requirements, resulting in a busbar configuration suitable for the target process.

[0052] Step S20: Based on the power distribution demand information, determine the bus configuration scheme corresponding to the target process.

[0053] Each target process is selected using a corresponding busbar selection method, resulting in a different busbar configuration scheme for each target process. Each target process can generate its corresponding busbar configuration scheme using the methods described above. The differences in busbar configuration schemes for each target process mainly lie in the number of buses, busbar capacity, and other busbar parameters. This embodiment primarily discusses how to generate a busbar configuration scheme suitable for a single target process. The busbar configuration scheme corresponding to the target process in this embodiment refers to the configuration of the number of buses required for the target process, as well as the busbar capacity and current of each busbar, to ensure the normal operation of all electrical equipment required by the target process.

[0054] In one alternative approach, bus configuration schemes corresponding to different power distribution demand information can be pre-built. In practical applications, a prominent button, such as a "Generate Configuration Scheme" button, can be placed on the power distribution interface. When the user clicks this button, the pre-built bus configuration schemes are searched based on the power distribution demand information to obtain the desired bus configuration scheme. This improves the efficiency of bus configuration scheme generation through the power distribution interface.

[0055] Step S30: Output the bus configuration scheme corresponding to the target process.

[0056] It should be noted that the power distribution interface can receive power distribution demand information for only a specific target process, and output the corresponding bus configuration scheme for that target process in the interface. Alternatively, it can receive power distribution demand information for multiple target processes and output bus configuration schemes for each process, improving the efficiency of generating bus configuration schemes for scenarios with multiple target processes.

[0057] In this embodiment, since different total installed capacity corresponds to different bus current carrying capacity and different equipment types have different requirements for bus stability, the total installed capacity of the target process and the equipment type of the electrical equipment required for the target process can comprehensively reflect the actual working conditions of the target process, so that the final generated bus configuration scheme can match the actual working conditions and improve the reliability of the power system.

[0058] In one feasible implementation, step S20 includes: Step S21: Obtain the electrical characteristic parameters of historical projects corresponding to the equipment type.

[0059] Among them, historical projects refer to power distribution projects that have been implemented in the past and are of the same type as the target process, such as battery mixing processes that use similar electrical equipment. The electrical characteristic parameters of historical projects are core data reflecting the electrical characteristics of the equipment.

[0060] Among these, the electrical characteristic parameters of historical projects are data from the actual operation of equipment in similar processes, rather than the theoretical rated values ​​on the equipment nameplate. For example, the electrical characteristic parameters of historical projects include, but are not limited to, historical total utilization factor, historical effective number of electrical equipment, and historical total installed power. These electrical characteristic parameters can accurately reflect the power consumption patterns of electrical equipment in actual production, making the parameter prediction of the target process systematic and providing a reference benchmark for real operating conditions.

[0061] In one alternative approach, an equipment database can be constructed based on the equipment types of electrical equipment used in mixing, cold pressing, die-cutting, assembly, and baking processes. This database also includes electrical characteristic parameters of one or more historical items for each electrical equipment. Each historical item includes one or more electrical devices. In practical applications, the equipment types required for the target process can be input into the power distribution interface. Based on these equipment types, the electrical characteristic parameters of historical items for the corresponding equipment types can be retrieved from the pre-constructed equipment database. Specifically, determining the equipment type for the target process in a new project by querying the equipment database can be achieved by first obtaining the equipment name or power rating of each electrical device required for the target process, and then querying the equipment database based on this name or power rating to obtain the equipment type for each electrical device required in the target process.

[0062] Step S22: Based on the electrical characteristic parameters of historical projects and the total installed power of the target process, determine the bus configuration scheme corresponding to the target process.

[0063] In one alternative approach, a mapping relationship between different electrical characteristic parameters, total installed capacity, and bus configuration schemes can be pre-established. During actual use, the mapping relationship can be found based on the electrical characteristic parameters of historical projects and the total installed capacity of the target process to obtain the corresponding bus configuration scheme.

[0064] In this embodiment, the bus configuration scheme corresponding to the target process is determined based on the electrical characteristic parameters of historical projects for the equipment type and the total installed power of the target process. During the generation of the bus configuration scheme using this system, the electrical characteristic parameters of historical projects corresponding to the equipment type are combined to ensure the scheme fits the actual operating scenario and reduces adaptation deviations. By associating the total installed power, the system ensures that the bus load-bearing capacity matches the actual demand, avoiding overload or resource waste. Furthermore, by jointly determining the bus configuration scheme corresponding to the target process using the electrical characteristic parameters of historical projects for the equipment type and the total installed power, the accuracy of the generated bus configuration scheme is improved.

[0065] In one feasible implementation, step S22 includes: Step S221: Estimate the electrical characteristic parameters of the target process based on the electrical characteristic parameters of historical projects.

[0066] The electrical characteristic parameters of the target process are estimated based on the electrical characteristic parameters of historical projects. For example, the electrical characteristic parameters of the target process include, but are not limited to: standard total utilization factor, effective number of standard electrical equipment, and standard historical total installed capacity. These parameters reflect the actual operating status of the electrical equipment in the target process and are the core basis for subsequent power adjustments.

[0067] In one alternative approach, the electrical characteristic parameters of historical projects can be used to estimate the electrical characteristic parameters of the target process using a pre-defined calculation model. For example, this pre-defined calculation model can select reasonable electrical characteristic parameters as the electrical characteristic parameters of the target process based on the normal distribution of the electrical characteristic parameters of historical projects. Alternatively, the pre-defined calculation model can filter the electrical characteristic parameters of the historical projects, for example, by removing the minimum and maximum values, and then selecting the largest one from the remaining electrical characteristic parameters as the electrical characteristic parameter of the target process.

[0068] The aforementioned preset calculation model can select reasonable electrical characteristic parameters as the electrical characteristic parameters of the target process based on the normal distribution of electrical characteristic parameters of historical projects. This can be achieved by: determining the dispersion and central tendency of electrical characteristic parameters of multiple historical projects; and obtaining the electrical characteristic parameters of the target process from the electrical characteristic parameters of multiple historical projects based on the dispersion and central tendency of electrical characteristic parameters of multiple historical projects.

[0069] Dispersion measures the degree to which a set of data deviates from its central value, reflecting the dispersion of the data. It reflects the magnitude of differences in the same electrical parameter value across different historical projects. For example, a high degree of dispersion in the historical total utilization factor of various historical projects indicates significant differences in this factor across different projects; a low degree of dispersion indicates that the historical total utilization factor is relatively similar across projects. Common metrics for measuring dispersion include variance and standard deviation.

[0070] Central tendency refers to the tendency of a set of data to converge toward its central value, reflecting typical or representative values. Central tendency can reflect the average level or common values ​​of a certain electrical characteristic parameter across multiple historical projects. For example, the historical total utilization factor across various historical projects; central tendency indicates the approximate range of that historical total utilization factor in most projects. Commonly used measures include the mean, median, and mode.

[0071] The electrical characteristic parameters of the aforementioned historical projects include the historical total utilization factor, while the electrical characteristic parameters of the target process include the standard total utilization factor. When there are multiple historical projects, there will also be multiple historical total utilization factors. The historical total utilization factor is a comprehensive indicator measuring the utilization level of electrical equipment in historical projects; it can be obtained by dividing the sum of the average active power of each piece of electrical equipment in the historical projects by the sum of the total power of each piece of equipment. The standard total utilization factor is determined based on the electrical characteristic parameters of the historical projects. Since each historical project has a corresponding historical total utilization factor, the standard total utilization factor here can be one of multiple historical total utilization factors. The process of obtaining the electrical characteristic parameters of the target process from the electrical characteristic parameters of multiple historical projects, based on their dispersion and central tendency, can specifically include: (1) Based on the dispersion and central tendency of multiple historical total utilization coefficients, construct a first normal distribution model; from the first normal distribution model, obtain the target historical total utilization coefficient corresponding to the cumulative probability set; use the target historical total utilization coefficient as the standard total utilization coefficient of the target process.

[0072] The cumulative probability of the historical total utilization coefficient represents the probability that the random variable takes a value less than or equal to a specific value. In the first normal distribution model, the cumulative probability corresponding to different historical total utilization coefficients can be calculated, reflecting the proportion of all possible cases where the historical total utilization coefficient does not exceed that specific value.

[0073] The set cumulative probability is a pre-determined cumulative probability value based on the actual working conditions and the characteristics of the target process. For example, this set cumulative probability can be set to 80%, meaning that when determining the standard total utilization coefficient of the target process, it may be desirable to find a target historical total utilization coefficient value such that the probability of all historical total utilization coefficients not exceeding this value is 80%. It should be noted that 80% can be used as a target threshold to determine the target historical total utilization coefficient. This indicates that this target historical total utilization coefficient is a relatively good but not extreme level among all historical total utilization coefficients, and has representative significance. It can be used to determine the standard total utilization coefficient of subsequent target processes, thereby improving the accuracy of the standard total utilization coefficient of the target process.

[0074] It should be noted that equipment utilization varies significantly across different production processes. For example, in some intermittent production processes, equipment may not operate at full capacity continuously, resulting in a lower standard total utilization factor (SGF); while in continuous production processes, equipment utilization may be higher. The SGF reflects the simultaneous operating characteristics of multiple pieces of equipment. In practical applications, the multiple electrical devices connected to the busbar do not operate at full capacity simultaneously. The SGF reflects the proportion of equipment simultaneously engaged in load, correcting for the ideal situation of all equipment operating at full capacity simultaneously, thus more closely approximating the simultaneity of actual loads.

[0075] The electrical characteristic parameters of the aforementioned historical projects include the effective number of historical electrical equipment units, while the electrical characteristic parameters of the target process include the effective number of standard electrical equipment units. When there are multiple historical projects, there are also multiple effective numbers of historical electrical equipment units. Specifically, for actual electrical equipment groups in historical projects where the power and operating modes of each piece of equipment are different, if they are converted into a hypothetical electrical equipment group where the power and operating modes of each piece of equipment are the same, while their maximum calculated load remains unchanged, then the number of units in this hypothetical electrical equipment group is the effective number of units in this actual electrical equipment group, i.e., the effective number of historical electrical equipment units. This effective number of historical electrical equipment units can be obtained by the ratio of the square of the sum of the power consumption of each piece of electrical equipment in the historical project to the sum of the squares of the power consumption of each piece of electrical equipment in the historical project. The effective number of standard electrical equipment units is determined based on the effective number of historical electrical equipment units in the historical projects. Since each historical project has a corresponding effective number of historical electrical equipment units, the effective number of standard electrical equipment units here can be one of multiple effective numbers of historical electrical equipment units. The above-mentioned method of obtaining the electrical characteristic parameters of the target process from the electrical characteristic parameters of multiple historical projects, based on the dispersion and central tendency of these parameters, may specifically include: (2) Based on the dispersion and central tendency of the effective number of multiple historical electrical equipment, a second normal distribution model is constructed. From the second normal distribution model, the target effective number of historical electrical equipment corresponding to the cumulative probability is obtained. The target effective number of historical electrical equipment is used as the standard effective number of electrical equipment for the target process.

[0076] In this context, the cumulative probability of the effective number of historical electrical devices represents the probability that the random variable takes a value less than or equal to a specific value. In the second normal distribution model, the cumulative probability corresponding to different effective numbers of historical electrical devices can be calculated, reflecting the proportion of all possible scenarios where the effective number of historical electrical devices does not exceed that specific value.

[0077] The set cumulative probability is a pre-determined cumulative probability value based on the actual working conditions and the characteristics of the target process. For example, this set cumulative probability can be set to 80%, meaning that when determining the effective number of standard electrical equipment units in the target process, it may be desirable to find a target historical effective number of electrical equipment units such that the probability of all historical effective numbers of electrical equipment units not exceeding this value is 80%. It should be noted that 80% can be used as a target threshold to determine the target historical effective number of electrical equipment units. This indicates that this target historical effective number of electrical equipment units is a better-than-average but not extreme level among all historical effective numbers of electrical equipment units, and has representative significance. It can be used to determine the effective number of standard electrical equipment units in subsequent target processes, thereby improving the accuracy of the effective number of standard electrical equipment units in the target process.

[0078] It should be noted that the standard effective number of electrical equipment units takes into account the actual number of equipment involved in operation. During the process, not all installed equipment may be put into use simultaneously, or different equipment may have different power contributions. The standard effective number of electrical equipment units allows for a more reasonable assessment of the overall impact of equipment on the total installed power, making the calculation results closer to reality.

[0079] Step S222: Based on the electrical characteristic parameters of the target process, correct the total installed power of the target process to obtain the target total installed power.

[0080] The target total installed power is the value obtained by correcting the total installed power of the target process using the electrical characteristic parameters of the target process. This target total installed power is closer to the actual operating conditions of the target process.

[0081] In one optional approach, the electrical characteristic parameters and total installed capacity of the determined target process are input into a preset calculation model. The underlying calculation logic of this model then uses the electrical characteristic parameters of the target process to correct the total installed capacity, thus obtaining the target total installed capacity. Because the total installed capacity of the target process can be corrected using its electrical characteristic parameters, the corrected total installed capacity more closely approximates the actual operating conditions of the target process. This breaks away from the limitations of traditional one-size-fits-all selection based on rated installed capacity, effectively avoiding the problem of excessively high bus parameters, and thereby improving the reliability of the power system.

[0082] Step S223: Based on the target total installed capacity, determine the bus configuration scheme corresponding to the target process.

[0083] In this embodiment, based on the equipment type of the electrical equipment required in the target process, the electrical characteristic parameters of historical projects corresponding to the equipment type are obtained; based on the electrical characteristic parameters of the historical projects, the electrical characteristic parameters of the target process are estimated; based on the electrical characteristic parameters of the target process, the total installed power of the target process is corrected. Finally, the bus configuration scheme determination module determines the bus configuration scheme corresponding to the target process based on the target total installed power. Since different equipment types have different electrical characteristics, the electrical characteristic parameters of historical projects provide electrical references for different equipment, ensuring the accuracy of the electrical characteristic parameters of the target process. On this basis, the total installed power of the target process is corrected based on the electrical characteristic parameters of the target process. The corrected total installed power is closer to the actual operating conditions of the target process, breaking the limitation of the traditional one-size-fits-all selection based on rated installed power. By determining the bus parameters through the corrected target total installed power, the problem of excessively high bus parameters is effectively avoided, thereby improving the reliability of the power system.

[0084] In one feasible implementation, step S222 includes: Step S2221: Based on the electrical characteristic parameters of the target process, calculate the comprehensive correction coefficient of the total installed power of the target process. The electrical characteristic parameters of the target process include the standard total utilization factor, the effective number of standard electrical equipment, and the standard historical total installed power.

[0085] The comprehensive correction factor is a factor used to correct the total installed power of the target process, thereby improving the reliability of the total installed power of the target process.

[0086] It should be noted that equipment utilization varies significantly across different production processes. For example, in some intermittent production processes, equipment may not operate at full capacity continuously, resulting in a lower standard total utilization factor (SGF); while in continuous production processes, equipment utilization may be higher. The SGF reflects the simultaneous operating characteristics of multiple pieces of equipment. In practical applications, the multiple electrical devices connected to the busbar do not operate at full capacity simultaneously. The SGF reflects the proportion of equipment simultaneously engaged in load, correcting for the ideal situation of all equipment operating at full capacity simultaneously, thus more closely approximating the simultaneity of actual loads.

[0087] The standard effective number of electrical equipment units takes into account the actual number of devices involved in operation. During the process, not all installed equipment may be put into use simultaneously, or different devices may have different power contributions. The standard effective number of electrical equipment units allows for a more reasonable assessment of the overall impact of the equipment on the total installed power, making the calculation results closer to reality.

[0088] During project operation, instantaneous peak load situations may occur, such as the simultaneous startup of certain equipment in production. The standard historical total installed capacity ensures that the power system still has sufficient power reserves when facing peak loads, avoiding problems such as system collapse and equipment damage due to insufficient power, and ensuring the stability and continuity of power system operation.

[0089] The comprehensive correction factor determined based on the above-mentioned standard total utilization factor, effective number of standard electrical equipment, and standard historical total installed power can comprehensively reflect the situation of equipment operating at full load simultaneously, the number of equipment actually participating in operation, and the situation of instantaneous peak load. By using this comprehensive correction factor to correct the total installed power of the target process, the obtained target total installed power is more in line with the actual working conditions, thus improving the accuracy of the target total installed power.

[0090] In one alternative approach, the comprehensive correction factor for the total installed power of the target process can be calculated based on the standard total utilization factor, the effective number of standard electrical equipment, and the standard historical total installed power. Specifically, a calculation model for calculating the comprehensive correction factor for the total installed power can be pre-constructed based on historical data, including the total utilization factor, the effective number of electrical equipment, the total installed power, and the comprehensive correction factor for the total installed power. In practical applications, the standard total utilization factor, the effective number of standard electrical equipment, and the standard historical total installed power of the target process can be input into this calculation model to obtain the comprehensive correction factor for the total installed power. This method allows for the rapid acquisition of the comprehensive correction factor for the total installed power.

[0091] Alternatively, a table can be pre-established based on historical data to represent the total utilization factor, the effective number of electrical devices, the total installed capacity, and the comprehensive correction factor for the total installed capacity. In practical applications, the comprehensive correction factor for the total installed capacity can be quickly obtained by looking up the table.

[0092] In another alternative approach, the comprehensive correction factors for the total installed power of the target process are calculated based on the electrical characteristic parameters of the target process, including (1) to (5): (1) Obtain the maximum coefficient associated with the standard total utilization factor and the effective number of standard electrical equipment.

[0093] The maximum load factor reflects the maximum output characteristics of the equipment load. Even if the equipment does not operate simultaneously, individual equipment may still reach its maximum load at a certain moment, such as during short-term overload or peak load. The maximum load factor is used to quantify the ratio of this maximum load to the average load. It describes the volatility and uncertainty of the load.

[0094] In one alternative approach, a relationship table can be pre-established based on the total utilization factor, the effective number of electrical devices, and the maximum coefficient. In practical applications, after determining the standard total utilization factor and the standard effective number of electrical devices, the maximum coefficient can be obtained by looking up the relationship table using these parameters.

[0095] (2) Calculate the comprehensive total load factor based on the maximum coefficient and the standard total utilization factor.

[0096] It is important to note that busbar calculations require considering both load simultaneity and maximum load to accurately determine the equivalent load factor that the busbar actually needs to bear. The comprehensive total load factor takes into account both load simultaneity and maximum load. In practical applications, considering only the standard total utilization factor ignores extreme cases of maximum load, leading to insufficient busbar capacity; considering only the maximum factor ignores the actual pattern of multiple devices not operating at full load simultaneously, resulting in excessively high busbar selection costs. Therefore, calculating the comprehensive total load factor by comprehensively considering both the maximum factor and the standard total utilization factor is to simultaneously account for the impact of load discrepancies and the occurrence of maximum load, obtaining a comprehensive load factor that better reflects the actual operating scenario, providing an accurate load basis for subsequent steps such as busbar selection.

[0097] In one alternative approach, the overall total load factor can be obtained by multiplying the maximum factor and the standard total utilization factor.

[0098] (3) Calculate the installation deviation correction coefficient based on the standard historical total installed power, standard total utilization factor, target process total installed power and comprehensive total load factor.

[0099] (4) The overall total load factor is corrected by the installed capacity deviation correction factor to obtain the overall correction factor.

[0100] The purpose of calculating the installed capacity deviation correction coefficient is to address the load characteristic mismatch problem caused by changes in installed capacity, ensuring that load calculations are adapted to the new installed capacity scale and providing accurate load basis for bus selection. When the total installed power of the target process in a new project changes, the comprehensive total load factor will change synchronously. If the target total installed power of the target process is predicted directly based on the comprehensive total load factor determined by historical projects, it will lead to a deviation between the estimated total installed power and the target total installed power of the target process, resulting in underestimation or overestimation of the load. Therefore, this embodiment does not use the comprehensive total load factor determined by historical projects to predict the target total installed power of the target process. Instead, a calibration step is introduced to calculate the installed capacity deviation correction coefficient based on the standard historical total installed power, standard total utilization factor, total installed power of the target process, and comprehensive total load factor. The installed capacity deviation correction coefficient is then used to correct the comprehensive total load factor to obtain the comprehensive correction coefficient; finally, the total installed power of the target process is corrected based on the comprehensive correction coefficient to obtain the target total installed power.

[0101] In this embodiment, an installation deviation correction factor Kj is introduced for correction. The installation deviation correction factor Kj can be obtained by the following formula: (1) Among them, in the above formula (1) This represents the total installed power of the target process, which is the sum of the rated power of all electrical equipment required for the target process. This represents the standard historical total installed capacity, which is the sum of the rated power of all electrical equipment in the historical projects. Indicates the standard total utilization factor. This represents the overall total load factor. This represents the installation deviation correction factor.

[0102] Therefore, the comprehensive correction factor for the total installed power of the target process can be obtained by the following formula: Kj1=k1 Kj. (2) Where Kj1 is the comprehensive correction coefficient.

[0103] By introducing a calibration process, an installation deviation correction factor is calculated based on the standard historical total installed power, standard total utilization factor, target process total installed power, and comprehensive total load factor. This installation deviation correction factor is then used to correct the comprehensive total load factor, resulting in a comprehensive correction factor, thus improving the accuracy of the comprehensive correction factor.

[0104] Step S2222: Calculate the target total installed power based on the comprehensive correction coefficient and the total installed power of the target process.

[0105] In one alternative approach, the target total installed power can be obtained by multiplying the comprehensive correction factor by the total installed power of the target process.

[0106] In this embodiment, the comprehensive correction coefficient calculation module calculates the comprehensive correction coefficient, and the target total installed power calculation module uses the comprehensive correction coefficient to correct the total installed power of the target process. This not only accurately reflects the actual power demand of the equipment, but also reasonably assesses the overall impact of the equipment on the total installed power, making the target total installed power more consistent with the actual working conditions and more accurate.

[0107] In one feasible implementation, step S223 includes: Step S2231: Calculate the bus current required for the target process based on the target total installed power.

[0108] In one alternative approach, after determining the target total installed capacity, the target total installed capacity is input into a preset calculation model to calculate the bus current required for the target process.

[0109] For example, assuming the bus current required for the target process is represented by I1, it can be obtained through formula (3): (3) in, The calculation result is the target total installed power. This represents the total installed power of the target process. Voltage U and power factor are also considered. The voltage U is a constant, and the power factor can be 390V. The value can be 0.93. The input to the preset calculation model can be the target total installed power, and the output can be the bus current of the target process. The median value. Output can be selected or not as needed. It should be noted that the preset calculation model of the above formula (3) is for three-phase electrical equipment. For single-phase electrical equipment, the above preset calculation model can be simply transformed to obtain the preset calculation model for single-phase electrical equipment.

[0110] Step S2232: Based on the bus current, determine the bus configuration scheme corresponding to the target process.

[0111] In one alternative approach, to avoid overload risks due to under-selection and to avoid investment waste and operational losses due to over-selection, the most suitable bus capacity is typically chosen between 65% and 85% of the load rate. Load rate = bus current / bus capacity, therefore bus capacity = bus current / load rate (65%~85%). For example, if the calculated bus current is 1850A, then the bus capacity is taken from 2176A to 2846A.

[0112] In another alternative approach, a table relating bus current and bus parameters is pre-set. By consulting the table relating bus current and bus parameters, the bus parameters that are compatible with the target process can be determined based on the bus current of the target process. This simplifies the calculation process and improves processing efficiency.

[0113] Assuming the bus parameters are bus capacity, the relationship between the preset bus current and the preset bus capacity is shown in Table 1 below: Table 1

[0114] Referring to Table 1, if the calculated bus current is 1000A (unit: amperes, for example), to ensure that the bus can safely carry 1000A of current, the bus capacity corresponding to 1114A in Table 1 can be selected as the bus parameter, in which case only one bus is needed; or, multiple bus capacities corresponding to 870A in Table 1 can be selected as the bus parameter to ensure that the final bus can carry 1000A of current. The specific bus capacity and number of busbars selected can be set according to actual test results or empirical values, and are not limited in this application.

[0115] Taking the target processes as mixing, cold pressing, die cutting, assembly, and baking as examples, Table 2 shows the bus configuration schemes for each target process: Table 2

[0116] As can be seen from Table 2 above, each target process can have one or more busbars.

[0117] It should be noted that the table above is only an example; in practical applications, the data in the table can be designed according to needs.

[0118] In this embodiment, the bus current required for the target process is calculated by correcting the target total installed power, and then the bus configuration scheme suitable for the target process is determined based on the bus current, thereby improving the accuracy of bus selection.

[0119] Based on the above embodiments of this application, in one embodiment of this application, content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, the power distribution demand information includes electrical characteristic parameters of non-production equipment, and the power distribution scheme also includes a transformer configuration scheme. (Refer to...) Figure 2 Following step S30, the method for generating the power distribution scheme further includes: Step S40: Determine the transformer configuration scheme based on the bus configuration scheme and electrical characteristic parameters of non-production equipment corresponding to each target process.

[0120] Step S50, output transformer configuration scheme.

[0121] It should be noted that the target process can be divided into two types: production process and non-production process. In this embodiment, the non-production equipment includes both non-production equipment in the production process and non-production equipment in the non-production process.

[0122] The electrical characteristic parameters of non-production equipment can be the total installed power of the non-production equipment and a preset second maximum coefficient. The total installed power of the non-production equipment is the sum of the rated power of all non-production equipment. If the rated power of each non-production piece of equipment is the same, then the total installed power of the non-production equipment equals the total number of non-production pieces of equipment. Rated power of a single non-production device. The electrical characteristic parameters of non-production devices can be included as part of the power distribution demand information and can be entered in the second area. The second maximum coefficient can be set to 2.

[0123] It should be noted that non-production equipment is not directly related to the production process, but it can still impact the overall power system of the project. Therefore, when determining the transformer configuration scheme, the usage of non-production equipment must be considered simultaneously. This non-production equipment serves as a latent load in the power system. Combining these latent loads with the aforementioned explicit production equipment can cover all actual load sources, better reflect actual operating conditions, and improve the reliability of transformer selection.

[0124] The transformer configuration scheme refers to the busbar configuration. This scheme can specify which busbar(s) each transformer corresponds to. These busbars can originate from the same target process or different target processes. The transformer configuration scheme may also include transformer parameters, including but not limited to the number of transformers, transformer capacity, and transformer specifications. This application does not impose any limitations on these parameters.

[0125] In one alternative approach, after outputting the bus configuration scheme corresponding to the target process, in response to the transformer configuration scheme generation instruction, a transformer configuration scheme is determined based on the bus configuration scheme corresponding to each target process and the electrical characteristic parameters of the non-production equipment, and the transformer configuration scheme is then output. Alternatively, after outputting the bus configuration scheme corresponding to the target process, the transformer configuration scheme can be automatically determined based on the bus configuration scheme corresponding to each target process and the electrical characteristic parameters of the non-production equipment, and the transformer configuration scheme can be automatically output.

[0126] In this embodiment, after generating the bus configuration scheme, a transformer configuration scheme is generated based on the bus configuration scheme corresponding to each target process and the electrical characteristic parameters of non-production equipment; the transformer configuration scheme is then output. During the generation of the transformer configuration scheme, the electrical characteristic parameters of the implicit load, non-production equipment, are considered. The generated transformer configuration scheme is no longer based solely on empirical estimation but is more closely aligned with actual operating conditions, thus improving the reliability of the power system.

[0127] In one feasible implementation, step S40 includes: Step S41: Based on the bus configuration scheme, obtain the electrical characteristic parameters of the bus in the corresponding target process.

[0128] The electrical characteristic parameters of the busbars are determined based on the busbar configuration scheme. While different busbars share the same electrical characteristic parameters, their values ​​may differ. For example, each busbar's electrical characteristic parameters may include a first maximum coefficient and a target total installed capacity. However, due to the different electrical equipment that can be mounted on each busbar, the corresponding values ​​for the first maximum coefficient and the target total installed capacity may vary. These electrical characteristic parameters provide calculation parameters for subsequently determining the apparent power of the transformer.

[0129] In one optional approach, when the bus configuration scheme includes the number of buses and the bus capacity, the above-mentioned determination of the electrical characteristic parameters of the buses in each bus configuration scheme based on the bus configuration scheme corresponding to each target process includes: pre-establishing a relationship table between the maximum coefficient of the bus, the total installed power, and the bus capacity. Based on the bus capacity, the relationship table between the preset maximum coefficient, the preset total installed power, and the preset bus capacity is used to obtain the first maximum coefficient and the target total installed power of the bus; the first maximum coefficient and the target total installed power are then used as the electrical characteristic parameters of the bus.

[0130] Step S42: Calculate the apparent power of the transformer based on the electrical characteristic parameters of the busbar and the electrical characteristic parameters of the non-production equipment.

[0131] The apparent power of a transformer refers to the total power that a transformer can transmit in a power system. The unit is usually kilovolt-amperes (kVA). It is an important indicator for measuring the size of a transformer and reflects the electrical load capacity that a transformer can bear.

[0132] Step S43: Determine the transformer configuration scheme based on the apparent power of the transformer.

[0133] The above-mentioned transformer configuration scheme based on the apparent power of the transformer includes: a table relating the apparent power of the transformer to the transformer parameters can be established in advance; in actual application, the transformer parameters that are compatible with the target project can be obtained based on the apparent power, the preset apparent power and the preset transformer parameters table.

[0134] It should be noted that, to avoid the risk of overload due to under-selection and the waste of investment and operational losses due to over-selection, the most suitable transformer capacity is usually selected between 65% and 85% of the load rate. Load rate = apparent power / transformer capacity, therefore, transformer capacity = apparent power / load rate.

[0135] When the bus configuration scheme includes bus capacity and the transformer parameters are transformer capacity, the relationship between the preset bus configuration scheme and the preset transformer parameters is shown in Table 3: Table 3

[0136] In this embodiment of the application, in the process of calculating the apparent power of the transformer, not only are the electrical characteristic parameters of the explicit loads such as the busbars in each production process taken into account, but also the electrical characteristic parameters of the implicit loads such as non-production equipment are taken into account. The calculation of the apparent power of the transformer is no longer just based on empirical estimation, but is more in line with the actual operating conditions, thereby improving the reliability of the power system.

[0137] In one feasible implementation, step S42 includes: Step S421: Determine the transformer simultaneity factor based on the electrical characteristic parameters of the busbar and the electrical characteristic parameters of the non-production equipment.

[0138] The transformer simultaneity factor is a coefficient introduced to account for the situation where multiple electrical devices or loads operate simultaneously, taking into account the fact that they will not all reach their maximum load at the same time. It reflects the probability that multiple loads supplied by a transformer will operate at maximum power simultaneously at a given moment, and its value typically ranges from 0 to 1. For example, if a transformer supplies power to multiple production processes, and the loads of each process do not reach their peak values ​​simultaneously, the transformer simultaneity factor is a parameter used to measure the degree of simultaneous use, allowing for a more accurate calculation of the transformer's actual load.

[0139] Step S422: The target total installed power of the bus is corrected by the transformer simultaneous factor, and the total installed power of the non-production equipment is corrected by the preset non-production equipment demand factor.

[0140] The target total installed capacity of the busbar represents the maximum power that the busbar can theoretically bear. It is an important indicator for measuring the power supply capacity of the busbar. However, in actual operation, since the equipment will not operate at full load at the same time, the actual load is usually less than the total installed capacity.

[0141] The total installed power of non-production equipment refers to the sum of the power of all non-production equipment. Similarly, in actual operation, non-production equipment will not reach its maximum power at the same time. It is necessary to combine parameters such as demand factor to determine its actual impact on transformer.

[0142] In one alternative approach, after obtaining the transformer simultaneity factor, the corrected target total installed capacity of the busbar is obtained by multiplying the transformer simultaneity factor by the target total installed capacity of the busbar. The corrected total installed capacity of the non-production equipment is obtained by multiplying the preset non-production equipment demand factor by the total installed capacity of the non-production equipment.

[0143] The preset non-production equipment demand coefficient can be set according to the experiment; for example, it can be set to 0.7.

[0144] For example, for the target total installed capacity Pbusto of the bus, the corrected bus power Pbuscorrect is obtained by multiplying the transformer simultaneity factor Ksimultaneity by the target total installed capacity of the bus. Pbus total; For the total installed power of non-production equipment, Pnon-production total, multiply the preset non-production equipment demand factor Kdemand by the total installed power of non-production equipment to obtain the corrected non-production equipment power Pnon-production corrected = Kdemand. P is not the total production capacity. For example, if the total installed capacity of the busbar is 1000kW and the transformer simultaneity factor is 0.8, then the corrected busbar power is 800kW; if the total installed capacity of the non-production equipment is 500kW and the demand factor is 0.7, then the corrected non-production equipment power is 350kW.

[0145] Step S423: Calculate the apparent power of the transformer based on the target total installed power corrected for the bus and the total installed power corrected for non-production equipment.

[0146] In one alternative approach, the corrected total installed capacity of the busbar and the corrected total installed capacity of the non-production equipment can be added together to obtain the corrected total active power. Simultaneously, the total reactive power needs to be known. This can be calculated separately for the busbar and non-production equipment, by multiplying their respective power factors by the active power. Then, the reactive power of the busbar and the reactive power of the non-production equipment are added together to obtain the total reactive power. Finally, the corrected total active power is added to the total reactive power to obtain the apparent power. This method, by considering active and reactive power separately, comprehensively reflects the load's power demand on the transformer, providing an accurate basis for transformer selection and capacity determination. This ensures that the transformer can meet the actual power demand during project operation while avoiding unnecessary capacity waste.

[0147] In another alternative approach, the target total installed capacity after bus correction can be added together with the total installed capacity after non-production equipment correction to obtain the transformer's active power. Then, the apparent power of the transformer can be obtained based on the ratio of the transformer's active power to the preset power factor. The preset power factor can be obtained experimentally and can be set to 0.93.

[0148] In this embodiment, the transformer simultaneity factor reflects the probability that both production and non-production equipment connected to the busbar will simultaneously reach maximum power. This factor can be determined more accurately by analyzing the electrical characteristic parameters of the busbar and non-production equipment. Similarly, the preset non-production equipment demand factor considers the simultaneous use of non-production equipment in actual operation, and the corrected total installed power of non-production equipment is closer to reality. Calculating the apparent power of the transformer based on these two corrected power values ​​allows for an accurate assessment of the transformer's load capacity in actual operation. This avoids errors caused by evaluating transformer load capacity solely based on total installed power. Overestimating the load capacity may lead to selecting a transformer with insufficient capacity, resulting in overload operation during peak load periods, affecting equipment lifespan, and even causing safety accidents. Underestimating the load capacity and selecting a transformer with excessive capacity will result in resource waste and increased investment. Accurate load capacity assessment provides a reliable basis for subsequent transformer selection.

[0149] In one feasible implementation, the electrical characteristic parameters of the busbar include a first maximum coefficient and a target total installed power, and the electrical characteristic parameters of the non-production equipment include a second maximum coefficient and a total installed power; step S421 includes: Step S4211: Based on the target total installed power of the bus, the first maximum coefficient, the total installed power of non-production equipment, and the second maximum coefficient, determine the target electrical characteristic parameters, wherein the target electrical characteristic parameters comprehensively reflect the different power characteristics of all production equipment and non-production equipment.

[0150] Step S4212: Determine the transformer simultaneity factor based on the target electrical characteristic parameters.

[0151] In one alternative approach, when the electrical characteristic parameters of the busbar include a first maximum coefficient and a target total installed power, and the electrical characteristic parameters of the non-production equipment include a second maximum coefficient and a total installed power, the average power of the busbar can be determined based on the ratio of the target total installed power of the busbar to the first maximum coefficient, and the average power of the non-production equipment can be determined based on the ratio of the total installed power of the non-production equipment to the second maximum coefficient. The total average power is obtained by summing the average power of the busbar and the average power of the non-production equipment. The total power is obtained by summing the target total installed power of the busbar and the total installed power of the non-production equipment. The peak power of the busbar is obtained by the difference between the target total installed power and the average power of the busbar; the peak power of the non-production equipment is obtained by the difference between the total installed power and the average power of the non-production equipment. The target peak power is obtained by square-taking the sum of the squares of the peak power of the busbar and the peak power of the non-production equipment. The transformer simultaneity coefficient is obtained by the ratio of the sum of the total average power and the target peak power to the total power.

[0152] It should be noted that the total average power focuses on the long-term steady state, reflecting the average time level of load power and avoiding the interference of short-term fluctuations on the overall load assessment; the total power focuses on the instantaneous dynamics, reflecting the real-time changes in load power and reflecting the fluctuation pattern of load over time; the target peak power focuses on extreme scenarios, reflecting the maximum boundary value of load power and covering the worst-case operating conditions. The combination of these three aspects achieves full coverage across the long-term, instantaneous, and extreme dimensions, avoiding biases in load characteristic assessments due to the limitations of data from a single dimension. Therefore, the target electrical characteristic parameters determined by these three factors can comprehensively reflect the power characteristics of all production and non-production loads in the target project across different dimensions.

[0153] For example, suppose there are three buses, namely bus 1, bus 2, and bus 3, with target total installed power of P1, P2, and P3 respectively, and first maximum coefficients of km1, km2, and km3 respectively. Suppose there is a non-production device with a total installed power of P4 and a second maximum coefficient of km4. Then, the calculation yields: Average power of busbar 1 = P1 / km1; Average power of busbar 2 = P2 / km2; Average power of busbar 3 = P3 / km3; Average power of non-production equipment = P4 / km4; Therefore, the total average power = the average power of bus 1 + the average power of bus 2 + the average power of bus 3 + the average power of non-production equipment.

[0154] For example, based on the above example, the total power = P1 + P2 + P3 + P4.

[0155] For example, based on the above example, we get: Peak power of bus 1 = P1 - Average power of bus 1; Peak power of bus 2 = P2 - Average power of bus 2; Peak power of bus 3 = P3 - Average power of bus 3; Peak power of non-production equipment = P4 - Average power of non-production equipment; Target peak power = .

[0156] For example, the transformer simultaneity factor = .

[0157] It should be noted that the peak power of the busbar and non-production equipment will not occur completely synchronously, and directly adding them will exaggerate the total peak power. Calculating the target peak power by taking the square root of the sum of squares takes into account the incomplete superposition effect of the two peaks, resulting in a result closer to the actual maximum load. Secondly, the total average power reflects the long-term stable load demand, while the target peak power reflects the short-term maximum superimposed load; the sum of the two is the upper limit of the comprehensive load that the transformer must bear. The ratio of this to the total power directly reflects the matching degree between the actual load to be borne and the theoretical total installed load, quantifying the probability of simultaneous load activation.

[0158] In this embodiment, target electrical characteristic parameters that can characterize the power characteristics of all production and non-production equipment are obtained by using the target total installed power of the bus, a first maximum coefficient, the total installed power of non-production equipment, and a second maximum coefficient. Based on these target electrical characteristic parameters, the transformer simultaneity factor is determined, so that the calculation of the transformer simultaneity factor is no longer simply based on the rated power, thus improving the accuracy of the calculation results.

[0159] Based on the above embodiments of this application, in one embodiment of this application, content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. Furthermore, the power distribution demand information also includes the process type of the target process, and the power distribution scheme also includes the power distribution equipment configuration scheme. Specifically, refer to... Figure 3 Before generating the bus configuration scheme, the method for generating the power distribution scheme also includes: Step S60: Determine the target power of the target process based on the process type of the target process and the equipment type of the electrical equipment required by the target process.

[0160] The target process can be divided into two types: production process and non-production process. Each target process may have different power requirements and equipment configurations. For a specific target process, multiple pieces of equipment can be installed, each with a different type. These devices execute the target process, and can perform the same or different processing flows within that process; this application does not impose any restrictions on this.

[0161] The aforementioned production process refers to a series of orderly operational steps undertaken to complete product manufacturing. The types of electrical equipment used in the production process can be categorized based on their power rating or their function within the process, such as dividing them into production equipment and non-production equipment. Non-production equipment is not directly related to the production process itself, but it can still impact the overall production process.

[0162] The aforementioned non-production processes refer to processes unrelated to product production. The equipment types for electrical equipment included in non-production processes can be non-production equipment.

[0163] In one optional approach, the equipment types required for each target process can be pre-set, i.e., a pre-built equipment database can be constructed to specify the equipment types required for different target processes. This equipment database can include information in four dimensions: process, process type, associated equipment, and equipment types. In practical applications, a selection interface for power distribution equipment can be displayed on the equipment parameter determination screen. After inputting the target process in the selection interface, the system can query the equipment database for the process type and the required equipment types, and then display the retrieved information on the selection interface to obtain the process type and equipment types for the target process.

[0164] The target power for a specific process is the actual effective operating power required for that process. Under some operating conditions, this power may be the rated power of the equipment, while under others it needs to be adjusted for load, correction factors, etc. Different process types and different equipment types will have different target power requirements due to the different operating conditions they correspond to.

[0165] In one alternative approach, a mapping relationship between different process types, equipment types, and target power can be pre-established. During practical application, the mapping relationship is looked up based on the process type and equipment type to obtain the target power for the target process. Since different process types and equipment types correspond to different operating conditions, the determined target power for the target process can better match the actual operating conditions.

[0166] Step S70: Based on the target power, determine the power distribution equipment configuration scheme corresponding to the target process.

[0167] Among them, the power distribution equipment is used to distribute the electrical energy output from the busbar required by the target process to each electrical device in the target process, so as to meet the power demand of each electrical device.

[0168] The power distribution equipment configuration plan includes power distribution equipment parameters, which may include power distribution equipment specifications, power distribution equipment type, etc. No specific limitations are specified here.

[0169] In one alternative approach, after determining the target power, a preset calculation model can be used to calculate the required current for the target process; then, based on the required current of the target process, a power distribution equipment configuration scheme suitable for the target process can be determined. In practical applications, after inputting the target power in the power distribution equipment selection interface, the preset calculation model can be used to calculate the power distribution equipment parameters suitable for the target process. The calculated power distribution equipment parameters are then used to generate a power distribution equipment configuration scheme, which is displayed in the selection interface to achieve the purpose of selecting power distribution equipment parameters. The calculation model method can meet the requirement of determining power distribution equipment parameters under any operating condition.

[0170] Alternatively, a mapping relationship between different installed capacities and power distribution equipment parameters can be pre-established. In practical applications, the power distribution equipment configuration scheme adapted to the target process is determined by using the target power and the pre-established mapping relationship. This method improves the efficiency of determining the power distribution equipment configuration scheme.

[0171] In this embodiment of the application, since different process types and different equipment types correspond to different operating scenarios, the target power and power distribution equipment configuration scheme required for the target process can be determined for different operating scenarios. This differentiated processing method based on different process types and equipment types enables the determined power distribution equipment configuration scheme to accurately match the actual operating conditions and improve the reliability of the power system.

[0172] In one feasible implementation, step S60 includes: Step S61: Based on the power distribution design parameters determined by the process type and equipment type, determine the target power of the target process. The process type includes production processes and non-production processes, and the equipment type includes production equipment and non-production equipment.

[0173] Among them, power distribution design parameters refer to the calculation parameters required to calculate the target power of the target process during the selection of power distribution equipment. These power distribution equipment parameters can be divided into basic equipment parameters, correction factors, and load factors according to their functions. Basic equipment data describes the physical attributes and upper capacity limits of the equipment and is the basic data for power distribution equipment selection. Basic equipment parameters include, but are not limited to, the number of equipment, the rated power of the equipment, and the number of equipment interfaces. Correction factors are used to correct the power. Load factors reflect the time or power weight of each process in the total production and are used to allocate installed capacity. Since the power distribution design parameters corresponding to different process types and different equipment types are different, the target power of the target process calculated based on different power distribution design parameters is also different. This can adapt to the calculation needs of target power under different operating scenarios, making the calculated target power more accurate.

[0174] The following will describe in detail the power distribution design parameters determined based on the process type and equipment type for different working scenarios, and the specific details of determining the target power of the target process.

[0175] (1) Based on the power distribution design parameters determined by the process type and equipment type, the target power of the target process is determined as follows: when the process type is a production process and the equipment type is a first power production equipment, the rated power of the first power production equipment is determined as the target power of the target process; wherein, the power distribution design parameters include the rated power.

[0176] The aforementioned production processes can include battery mixing, cold pressing, die-cutting, assembly, and baking. In addition to the processes mentioned above, the production processes in this application can also be other processes in battery manufacturing, such as battery formation, capacity measurement, or sorting, etc., without specific limitations. Each production process can have multiple electrical devices, and each type of electrical device is different.

[0177] For example, the equipment for the mixing process can be electrode slurry mixing tanks, batching pumps, dispersers, etc. For the cold pressing process, the equipment can be electrode cold pressing machines, tension control roller motors, conveyor belt motors, etc. For the die-cutting process, the equipment can be electrode die-cutting machines, feeding motors, waste recycling motors, etc. For the assembly process, the equipment can be stacking / winding machines, electrolyte injection pumps, core-packaging machines, etc. For the baking process, the equipment can be vacuum baking ovens, vacuum pumps, temperature circulating fans, etc. Specifically, the mixing process refers to mixing the positive / negative electrode active materials, conductive agents, binders, and solvents to prepare a uniform electrode slurry. The cold pressing process refers to pressing the coated electrode sheets at room temperature to increase material density, reduce thickness, and enhance conductivity. The die-cutting process refers to precisely cutting the cold-pressed electrode sheets and separators according to the battery dimensions to ensure assembly accuracy. The assembly process refers to stacking / winding the positive electrode sheets, separators, and negative electrode sheets, and assembling them with the electrolyte and casing to form a battery core pack / finished battery. The baking process refers to baking the electrodes, separators, and casing at high temperatures to remove moisture and impurities, and to prevent gas generation and short circuits inside the battery.

[0178] The equipment types used in the aforementioned production processes are categorized based on their rated power, specifically into two types: first-power production equipment and second-power production equipment. First-power production equipment refers to equipment with higher operating power, while second-power production equipment refers to equipment with lower operating power. In practical applications, production equipment with a power rating lower than a set value can be designated as second-power production equipment, while equipment with a power rating greater than or equal to a set value can be designated as first-power production equipment. For example, the set power rating could be 90 kilowatts.

[0179] Since the first power production equipment is a high-power production device, its rated power is the maximum power value that can be safely operated for a long period of time, clearly marked during the equipment's design and manufacturing. In actual production, the operating load of such equipment usually fluctuates around its rated power, and to ensure the safe and stable operation of the equipment, the power distribution system needs to be configured with capacity according to its rated power to cope with situations of full load or short-term overload. Therefore, the rated power of the first power production equipment can be determined as the target power for this production process. This ensures that the power distribution equipment has sufficient margin and can meet production needs.

[0180] Understandably, when the process type is a production process and the equipment type is a first-power production equipment, the rated power of the first-power production equipment is determined as the target power of the target process. This enables the determination of the target power under the condition of high-power production equipment in the production process, so that the parameters of the power distribution equipment determined subsequently meet the requirements of this condition and improve the reliability of the power system under this condition.

[0181] (2) The target power of the target process is determined based on the power distribution design parameters determined by the process type and equipment type. In the case that the process type is a production process and the equipment type is a second power production equipment, the target power of the target process is determined according to the number of second power production equipment, the number of interfaces of the second power production equipment, the rated power of the second power production equipment and the first preset power distribution equipment simultaneity coefficient. The power distribution design parameters include the number of second power production equipment, the number of interfaces of the second power production equipment, the rated power of the second power production equipment and the first preset power distribution equipment simultaneity coefficient.

[0182] The number of secondary power production devices can be one or more. If there are multiple devices, each device can have the same or different power outputs. For example, multiple secondary power production devices with different power outputs can be used depending on the actual situation.

[0183] The number of interfaces for the second type of low-power production equipment refers to the number of ports that can be connected to loads on each device. For example, a small motor controller with three motor connection ports means that this controller can connect and drive a maximum of three small motors simultaneously. These three ports are the number of interfaces, which directly determines the total number of loads that a single device can drive. The number of interfaces for low-power equipment directly corresponds to the maximum number of operable loads. For example, if a single production device has four interfaces, with each interface corresponding to a 1kW small load, then the maximum theoretical load of this device is four... 1kW = 4kW; Considering the number of equipment, such as two such production machines, the target power for the target process is 2kW. 4 1kW = 8kW.

[0184] The first preset power distribution equipment simultaneity coefficient is a correction coefficient characterizing the probability that multiple production equipment will be put into operation simultaneously and reach full load. It is used to quantify the actual scenario where not all production equipment will work at full load at the same time. It can be determined experimentally; for example, the first preset power distribution equipment simultaneity coefficient can be set to 0.6.

[0185] Since the second power production equipment is a low-power production equipment, while the current of a single low-power device is small, the total current increases significantly when multiple devices start simultaneously. If the power distribution equipment is selected based solely on the power of a single device, the total current exceeding the limit could lead to tripping, overheating of the lines, or even a fire. Therefore, to avoid overload and ensure safe operation of the equipment, this application determines the power of the target process based on the number of second-power production devices, the number of interfaces of the second-power production devices, and the rated power of the second-power production devices; then, it uses a first preset power distribution equipment simultaneity coefficient to correct the power of the target process, thus obtaining the target power of the target process.

[0186] In one optional approach, determining the power of the target process based on the number of second-power production devices, the number of interfaces of the second-power production devices, and the rated power of the second-power production devices includes: for second-power production devices with the same number of interfaces and rated power, the power of the target process can be obtained by multiplying the number of second-power production devices, the number of interfaces of the second-power production devices, and the rated power of the second-power production devices. For second-power production devices with different numbers of interfaces and rated power, the power of each second-power production device needs to be calculated separately based on the number of interfaces and rated power of each type of second-power production device; then, the power of each type of second-power production device is added together to obtain the power of the target process.

[0187] For example, assuming there are only two second-power production devices in the target process, and these two second-power production devices have the same rated power P and the same number of interfaces n, then the power of the target process = the rated power P of the second-power production devices. Number of interfaces n 2, where 2 represents the number of second power production equipment.

[0188] Assuming the rated power P and the number of interfaces n of the two secondary power production devices are different, then the power of each secondary power production device needs to be calculated separately and then added together to obtain the power of the target process. The calculation formula can be: Power of the target process = Rated power P1 of the secondary power production device Number of interfaces n1 + Rated power P2 of the second power production equipment Number of interfaces n2.

[0189] In another alternative approach, the power of the target process is corrected by using a first preset power distribution equipment simultaneity factor to obtain the target power of the target process. This includes multiplying the first preset power distribution equipment simultaneity factor by the power of the target process to obtain the target power of the target process.

[0190] It should be noted that, since the core characteristic of low-power equipment is its distributed layout and phased start-up and shutdown, for example, 10 low-power devices will not operate at full load simultaneously. The first preset power distribution equipment synchronicity factor is preset based on the operating data of similar processes or equipment and industry experience, essentially quantifying the time synchronization of equipment operation. If the power of the target process mentioned above is directly used as the target power, it is equivalent to assuming that all equipment operates 100% simultaneously, which is completely unrealistic. Multiplying by the first preset power distribution equipment synchronicity factor eliminates the load portion that cannot operate simultaneously, accurately reflecting the real power demand under this operating condition.

[0191] Understandably, by obtaining the process type of the target process and the equipment type of the electrical equipment required for the target process; when the process type is a production process and the equipment type is a second-power production equipment, the target power of the target process is determined based on the number of second-power production equipment, the number of interfaces of the second-power production equipment, the rated power of the second-power production equipment, and the first preset power distribution equipment simultaneity coefficient; based on the target power, the parameters of the power distribution equipment adapted to the target process are determined. In this way, the target power of the low-power production equipment under the production process is determined, ensuring that the subsequently determined power distribution equipment parameters meet the requirements of this operating condition, avoiding overload, ensuring safe equipment operation, and improving the reliability of the power system under this operating condition.

[0192] (3) Based on the power distribution design parameters determined by the process type and equipment type, the target power of the target process is determined as follows: when the process type is a production process and the equipment type is a non-production equipment, the total operating power of the non-production equipment in the production process is corrected by using the first preset correction coefficient, the second preset power distribution equipment simultaneity coefficient, and the preset load ratio associated with the production process to obtain the target power of the target process; wherein, the power distribution design parameters include the first preset correction coefficient, the second preset power distribution equipment simultaneity coefficient, the preset load ratio associated with the production process, and the total operating power of the non-production equipment in the production process.

[0193] Among them, non-production equipment in the production process can be power equipment or other non-production equipment, without specific limitations.

[0194] The first preset correction coefficient is a parameter value determined by experiments. This first preset correction coefficient can be set to 0.23, and it is used to correct the total operating power of non-production equipment in the production process, so that the target power of the target process is more in line with the actual working conditions. The first preset correction coefficient can be the same for different production processes.

[0195] The second preset power distribution equipment simultaneity coefficient is a correction coefficient representing the probability that multiple non-production equipment will be put into operation and reach full load during a production process. It is used to quantify the actual scenario where not all non-production equipment will work at full load at the same time. It can be determined experimentally; for example, the second preset power distribution equipment simultaneity coefficient can be set to 0.85. The second preset power distribution equipment simultaneity coefficient can be the same for different production processes.

[0196] The preset load ratio associated with each production process is a pre-set percentage of non-production equipment among all electrical devices used in that process, based on industry experience, historical operating data, or process requirements. Different production processes have different percentages of non-production equipment, resulting in different preset load ratios associated with each process.

[0197] The total operating power of non-production equipment in the production process is obtained by summing the electrical characteristic parameters of each non-production device in the production process.

[0198] In one optional approach, the target power of the target process can be obtained by multiplying a first preset correction coefficient, a preset load ratio associated with the production process, the total operating power of non-production equipment in the production process, and a second preset simultaneity coefficient for power distribution equipment. This method enables the calculation of the target power for non-production equipment operating conditions within a production process, ensuring the calculated target power better matches the requirements of that condition. Specifically, the calculation formula can be expressed as: Target power of the target process = Total operating power of non-production equipment in the production process. First preset correction coefficient Preset load ratio associated with production processes Second preset power distribution equipment simultaneous coefficient.

[0199] In another alternative approach, a mapping table can be pre-established between a first preset correction coefficient, a second preset simultaneity coefficient for power distribution equipment, a preset load ratio associated with the production process, the total operating power of non-production equipment in the production process, and the target power of the target process. In actual use, the target power of the target process is obtained by looking up the table based on the first preset correction coefficient, the second preset simultaneity coefficient for power distribution equipment, the preset load ratio associated with the production process, and the total operating power of non-production equipment. Specifically, this mapping table is shown in Table 4. Table 4

[0200] In Table 4, ΣP_operation represents the total operating power of non-production equipment in the production process, K1 represents the first preset correction coefficient, and K_box represents the second preset simultaneity coefficient of power distribution equipment. As can be seen from Table 4, the preset load ratios for different production processes may differ, the first preset correction coefficients for different production processes may be the same, the second preset simultaneity coefficient of power distribution equipment for different production processes may be the same, and the total operating power of non-production equipment differs in different production processes due to the different number of non-production equipment.

[0201] Understandably, by obtaining the process type of the target process and the equipment type of the electrical equipment required for the target process; when the process type is a production process and the equipment type is non-production equipment, the total operating power of the non-production equipment in the production process is corrected using a first preset correction coefficient, a second preset power distribution equipment simultaneity coefficient, and a preset load ratio associated with the production process, thus obtaining the target power of the target process; based on the target power, the power distribution equipment parameters adapted to the target process are determined. In this way, the target power of non-production equipment under the production process is determined, ensuring that the subsequently determined power distribution equipment parameters meet the requirements of this operating condition, avoiding overload, ensuring safe equipment operation, and improving the reliability of the power system under this operating condition.

[0202] (4) Based on the power distribution design parameters determined by the process type and equipment type, the target power of the target process is determined as follows: when the process type is a non-production process and the equipment type is a non-production equipment, the total operating power of the non-production equipment in the non-production process is corrected by using the first preset correction coefficient, the second preset correction coefficient, the third preset power distribution equipment simultaneity coefficient, and the preset load ratio associated with the non-production process, so as to obtain the target power of the target process; wherein, the power distribution design parameters include the first preset correction coefficient, the second preset correction coefficient, the third preset power distribution equipment simultaneity coefficient, the preset load ratio associated with the non-production process, and the total operating power of the non-production equipment in the non-production process.

[0203] Non-production processes can include fire protection processes, maintenance processes, lighting processes, etc., without specific limitations. For example, non-production equipment in a non-production process can be a three-section electrical box. A three-section electrical box is a type of distribution box in a low-voltage power distribution system. Its internal circuits or protection devices are designed in three sections, corresponding to the three core stages of power distribution and protection. These include the first stage, which is responsible for receiving the main power supply and undertaking the main switch and main protection functions for the overall power distribution; the second stage, which is used to divide the main power supply into multiple branches and distribute them to different loads; and the third stage, which is used for refined power distribution for specific equipment or scenarios. For the first stage, the corresponding non-production equipment can be a main circuit breaker; for the second stage, the corresponding non-production equipment can be lighting equipment, low-voltage equipment, maintenance equipment, etc. For the third stage, the corresponding non-production equipment can be fire protection equipment, fans, etc.

[0204] The definition of the first preset correction coefficient can be found in the above embodiment.

[0205] The second preset correction coefficient is a parameter value determined by experiments. This second preset correction coefficient can be set to 0.3. It is used to correct the total operating power of non-production equipment in non-production processes, so that the target power of the target process is more in line with the actual operating conditions. This second preset correction coefficient can be the same for different non-production processes.

[0206] The third preset power distribution equipment simultaneity coefficient is a correction coefficient representing the probability that multiple non-production equipment will be put into operation simultaneously and reach full load in a non-production process. It is used to quantify the actual scenario where not all non-production equipment will work at full load at the same time. It can be determined experimentally; for example, the third preset power distribution equipment simultaneity coefficient can be set to 0.85. The third preset power distribution equipment simultaneity coefficient can be the same for different non-production processes.

[0207] The preset load ratio associated with non-production processes is a pre-set percentage of non-production equipment among all electrical devices used in that non-production process, based on industry experience, historical operating data, or process requirements. Different percentages of non-production equipment in different non-production processes result in different preset load ratios associated with those processes.

[0208] In one optional approach, the target power of the target process can be obtained by multiplying a first preset correction coefficient, a second preset correction coefficient, a preset load ratio associated with the non-production process, the total operating power of non-production equipment in the non-production process, and a third preset simultaneity coefficient for power distribution equipment. This method enables the calculation of the target power for non-production equipment operating conditions within a non-production process, ensuring that the calculated target power more closely matches the requirements of that operating condition. Specifically, the calculation formula can be expressed as: Target power of the target process = Total operating power of non-production equipment in the non-production process. First preset correction coefficient Second preset correction coefficient Preset load ratios not associated with production processes The third preset power distribution equipment simultaneous coefficient.

[0209] In another alternative approach, a mapping table can be pre-established between a first preset correction coefficient, a second preset correction coefficient, a third preset power distribution equipment simultaneity coefficient, a preset load ratio associated with non-production processes, the total operating power of non-production equipment in non-production processes, and the target power of the target process. In actual use, the target power of the target process is obtained by looking up the table based on the first preset correction coefficient, the second preset correction coefficient, the third preset power distribution equipment simultaneity coefficient, the preset load ratio associated with non-production processes, and the total operating power of non-production equipment. Specifically, this mapping table is shown in Table 5. Table 5

[0210] In Table 5, ΣP_operation represents the total operating power of non-production equipment in non-production processes, K1 represents the first preset correction coefficient, K2 represents the second preset correction coefficient, and K_box represents the third preset simultaneity coefficient of power distribution equipment. As can be seen from Table 5, the preset load ratios for different non-production processes may be different, the first preset correction coefficients for different non-production processes may be the same, the second preset correction coefficients for different non-production processes may be the same, and the third preset simultaneity coefficient of power distribution equipment for different non-production processes may be the same. Due to the different numbers of non-production equipment in different non-production processes, the total operating power of the non-production equipment is different.

[0211] Understandably, by obtaining the process type of the target process and the equipment type of the electrical equipment required for the target process; when the process type is a non-production process and the equipment type is non-production equipment, the total operating power of the non-production equipment in the non-production process is corrected using a first preset correction coefficient, a second preset correction coefficient, a third preset power distribution equipment simultaneity coefficient, and a preset load ratio associated with the non-production process, thus obtaining the target power of the target process; based on the target power, the power distribution equipment parameters adapted to the target process are determined. In this way, the target power of the non-production equipment under the non-production process is determined, ensuring that the subsequently determined power distribution equipment parameters meet the requirements of this operating condition, avoiding overload, ensuring safe equipment operation, and improving the reliability of the power system under this operating condition.

[0212] In this embodiment, the process type of the target process and the equipment type of the electrical equipment required by the target process are obtained. Based on the power distribution design parameters determined by the process type and equipment type, the target power required by the target process is determined. Finally, based on the target power, the power distribution equipment parameters adapted to the target process are determined. Since the power distribution design parameters corresponding to different process types and different equipment types are different, the above method can adapt to the calculation requirements of target power under different operating conditions, making the calculated target power more accurate.

[0213] In one feasible implementation, step S70 includes: Step S71: Calculate the required current for the target process based on the target power, preset power factor, and preset load rate.

[0214] Step S72: Determine the power distribution equipment configuration scheme corresponding to the target process based on the required current of the target process.

[0215] Among them, the demand current refers to the key current parameter used to determine the parameters of the power distribution equipment when selecting a power distribution box, based on the target power. It is one of the core bases for selecting power distribution equipment and represents the maximum demand current that the power distribution equipment needs to carry.

[0216] The above calculation of the target process's required current based on the target power, preset power factor, and preset load rate includes: inputting the target power into a preset calculation model, which calculates the required current of the target process using the target power, preset power factor, and preset load rate. Specifically, the product of voltage, preset power factor, preset load rate, and the phase voltage to line voltage conversion factor of the three-phase circuit can be calculated. The required current of the target process is obtained based on the ratio of the target power to this product. Here, the phase voltage to line voltage conversion factor of the three-phase circuit can be set to... .

[0217] Assuming the current requirement of the target process is represented by I, it can be obtained through the following formula: .

[0218] Where P represents the target power; U represents the voltage; its possible value is 390V; The preset power factor can be obtained experimentally, for example, it can be set to 0.85; the preset load rate can also be obtained experimentally, for example, it can be set to 85%. It should be noted that the target power mentioned above can be used as input to the preset calculation model, and the required current of the target process can be used as output to the preset calculation model. The above formula is for three-phase electrical equipment. For single-phase electrical equipment, the above formula can be simply modified to obtain a preset calculation model suitable for single-phase electrical equipment.

[0219] The above-mentioned determination of the power distribution equipment configuration scheme corresponding to the target process based on the required current of the target process includes: obtaining the target power distribution equipment specifications and target power distribution equipment quantity suitable for the target process based on the relationship table between the required current of the target process and the preset power distribution equipment current, preset power distribution equipment specifications, and preset power distribution equipment quantity. The target power distribution equipment specifications and target power distribution equipment quantity are then determined as the power distribution equipment parameters suitable for the target process.

[0220] For example, taking the power distribution equipment parameters as power distribution equipment specifications and quantity as an example, the above relationship table can be shown in Table 6: Table 6

[0221] As can be seen from Table 6 above, when the required current is 160A, the corresponding power distribution equipment parameters to meet this requirement include one power distribution device with a specification of 200A. When the required current is 1000A, the corresponding power distribution equipment parameters to meet this requirement include one power distribution device with a specification of 630 and one power distribution device with a specification of 500.

[0222] Understandably, by establishing a relationship table between the target process's required current, the preset power distribution equipment current, the preset power distribution equipment specifications, and the preset power distribution equipment quantity, the target power distribution equipment specifications and quantity suitable for the target process can be obtained based on this table, thus yielding the power distribution equipment parameters suitable for the target process. This method allows for rapid location of matching power distribution equipment parameters after the required current is determined, improving the matching efficiency of power distribution equipment parameters.

[0223] In this embodiment, the required current for the target process is calculated based on the target power, preset power factor, and preset load rate. Based on the required current of the target process, the parameters of the power distribution equipment adapted to the target process are determined. Since the required current is calculated based on the determined target power, combined with the preset power factor and preset load rate, the current calculation closely matches the actual operating characteristics of the equipment. This avoids both under-matching leading to overload of the power distribution equipment and over-matching causing waste of equipment and costs.

[0224] Based on the above embodiments of this application, in one embodiment of this application, content that is the same as or similar to the above embodiments can be referred to the above description, and will not be repeated hereafter. In addition, the power distribution scheme also includes a cable configuration scheme; refer to... Figure 4 After step S70, the following steps are also included: Step S80: Based on the power distribution equipment configuration scheme and the target process, determine the cable configuration scheme corresponding to the target process.

[0225] Step S90: Output the cable configuration scheme corresponding to the target process.

[0226] Cables are the core carriers of electrical energy transmission between power distribution equipment and power consumption equipment. One end of the cable connects to the outgoing terminal of the power distribution equipment, and the other end connects to the junction box of the power consumption equipment. Insufficient cable parameters can lead to cable overheating, insulation aging, and even short circuits and fires; conversely, redundant parameters can significantly increase procurement costs and waste resources. Therefore, accurately and reasonably determining cable parameters under different operating conditions is crucial.

[0227] The cable configuration plan includes cable parameters. These parameters can include cable specifications, the number of cables for each specification, and so on.

[0228] In one alternative approach, a relationship table can be pre-established between different preset procedures, preset power distribution equipment parameters, and preset cable parameters. During practical application, the mapping relationship is looked up based on the target procedure and the power distribution equipment parameters adapted to it to obtain the cable parameters adapted to the target procedure.

[0229] In another alternative approach, the cable core count structure corresponding to the target process can be found first from a table showing the relationship between preset processes and preset cable core count structures. Then, based on the cable core count structure and power distribution equipment parameters, the cable parameters suitable for the target process can be found from a table showing the relationship between preset cable core count structures, preset power distribution equipment parameters, and preset cable parameters. Here, the power distribution equipment parameters can be the power distribution equipment current.

[0230] For example, the relationship between the above-mentioned preset procedures and the preset cable core count structure is shown in Table 7: Table 7

[0231] The cable selection / 3+2 mentioned above means three live wires + one neutral wire + one PE wire, and the cable selection / 4+1 mentioned above means three live wires + one neutral wire + one PE wire.

[0232] The relationship between the preset cable core count structure, preset power distribution equipment parameters, and preset cable parameters mentioned above is shown in Table 8: Table 8

[0233] As can be seen from Tables 7 and 8 above, for example, when the target process is cold die-cutting, the corresponding cable core count structure can be cable selection / 3+2; if the current of the current power distribution equipment is 125 A, the selected cable parameters can be 3... 50+2 25. When the target process is chemical formation, the corresponding cable core count structure can be cable selection / 4+1; if the current of the current power distribution equipment is 315A, the selected cable parameters can be 4... 150+70.

[0234] In this embodiment of the application, after determining the power distribution equipment configuration scheme, a cable configuration scheme adapted to the target process is determined based on the target process and the power distribution equipment configuration scheme adapted to the target process, so as to meet the generation requirements of cable configuration scheme under different working conditions and make the generated cable configuration scheme adapted to the actual working conditions.
