Abstract
Description
Technical Field
[0001] This application relates to the field of power distribution technology, and in particular to methods, apparatus, equipment, storage media and program products for determining bus parameters. Background Technology
[0002] In industrial power distribution design, the accuracy of busbar selection is crucial. Traditional methods rely mainly on the designer's experience, using fixed coefficients to estimate busbar current, and then determining busbar parameters and busbar type based on the busbar current. However, this approach results in selections that are not applicable to new projects with different equipment types. Busbar selections often deviate from reality, either being too conservative and wasting resources or too risky and posing safety hazards. Summary of the Invention
[0003] The main purpose of this application is to provide a method, apparatus, equipment, storage medium and program product for determining bus parameters, which aims to determine the bus parameters based on the bus current and ensure that the bus can accurately match the actual working conditions of the new project, thereby avoiding the overload risk caused by under-selection and the investment waste and operating losses caused by over-selection.
[0004] To achieve the above objectives, this application proposes a method for determining bus parameters. The method includes: obtaining the process steps of a new project; determining the product type of the new project based on the process steps; determining the equipment type of the new project based on the product type; determining the electrical characteristic parameters of historical projects corresponding to the equipment type based on the equipment type; calculating the bus current of the new project based on the first total installed capacity of the new project and the electrical characteristic parameters of historical projects corresponding to the equipment type; and determining bus parameters suitable for the new project based on the bus current, thereby determining a bus suitable for the new project.
[0005] In this embodiment, the process of the new project is obtained, and then the equipment type of the new project is determined. The electrical characteristic parameters of the historical projects of the corresponding equipment type are matched according to the equipment type of the new project. Based on the first total installed power of the new project and the electrical characteristic parameters of the historical projects of the corresponding equipment type, the bus current of the new project is determined. This method of determining the bus current differently according to the equipment type overcomes the limitations of the traditional fixed coefficient method. It enables the bus parameters determined based on the bus current and the bus to accurately match the actual working conditions of the new project. This avoids the overload risk caused by under-selection and also avoids the investment waste and operating losses caused by over-selection.
[0006] In one embodiment, the equipment type includes a first equipment type, wherein the cable width of the first equipment type is greater than a preset threshold; the electrical characteristic parameters include: historical calculation coefficient and theoretical utilization coefficient; determining the electrical characteristic parameters of historical projects corresponding to the equipment type of the new project includes: when the equipment type of the new project is the first equipment type, determining the historical calculation coefficient according to a first preset value; and determining the theoretical utilization coefficient according to the historical calculation coefficient and the historical measured maximum coefficient of historical projects corresponding to the equipment type.
[0007] In one embodiment, the equipment type includes a second equipment type, wherein the cable width of the second equipment type is less than a preset threshold; the electrical characteristic parameters include: historical calculation coefficient and theoretical utilization coefficient; determining the electrical characteristic parameters of historical projects corresponding to the equipment type of the new project includes: when the equipment type of the new project is the second equipment type, determining the historical calculation coefficient according to the first preset value; and determining the theoretical utilization coefficient according to the second preset value.
[0008] This embodiment defines the core components of electrical characteristic parameters (theoretical calculation coefficient K1, theoretical utilization coefficient Kut`) and clarifies the different strategies for wide-width and narrow-width devices in acquiring these parameters. Wide-width devices prioritize accuracy and use historical data for calculation, while narrow-width devices prioritize efficiency and use preset values for calculation. This achieves adaptability to different device types, balancing calculation efficiency and accuracy.
[0009] In one embodiment, the historical measured maximum coefficient is obtained through the following steps: obtaining the historical total installed power, historical measured average power, and equivalent number of historical devices for historical projects corresponding to the equipment type; calculating the historical measured utilization coefficient based on the historical total installed power and the historical measured average power; and determining the historical measured maximum coefficient based on the historical measured utilization coefficient and the equivalent number of historical devices.
[0010] This embodiment specifically defines the steps for obtaining the historical measured maximum coefficient Km of wide-span equipment. Specifically, it calculates the historical measured utilization coefficient using the historical total installed power and the historical measured average power, and then determines Km by combining this with the equivalent number of historical equipment units. This establishes a reliable Km value determination process based on historical measured data for wide-span equipment, laying the foundation for accurate calculations.
[0011] In one embodiment, when there are multiple historical items corresponding to the device type, there are multiple historical measured utilization coefficients and multiple equivalent number of historical devices; determining the maximum historical measured coefficient based on the historical measured utilization coefficient and the equivalent number of historical devices includes: sorting the multiple historical measured utilization coefficients in descending order, removing some data at both ends, and taking the maximum value among the remaining data as the standard utilization coefficient; sorting the multiple equivalent number of historical devices in descending order, removing some data at both ends, and taking the maximum value among the remaining data as the standard equivalent number of devices; and determining the maximum historical measured coefficient based on the standard utilization coefficient and the standard equivalent number of devices.
[0012] In this embodiment, a data cleaning and optimization method (e.g., the 80% probability maximum value method) is proposed for multiple historical projects. By removing extreme values and taking the maximum, the "standard utilization coefficient" and "equivalent number of standard equipment" are obtained, which are used to determine the final historical measured maximum coefficient. This eliminates abnormal interference in historical data, making the benchmark parameters used for calculation more representative and robust, and improving the reliability of the selection.
[0013] In one embodiment, the electrical characteristic parameters include: historical total installed capacity, historical calculation coefficient, and theoretical utilization coefficient; the step of calculating the bus current of the new project based on the first total installed capacity of the new project and the electrical characteristic parameters of historical projects corresponding to the equipment type includes: calibrating the historical calculation coefficient based on the first total installed capacity of the new project, the historical total installed capacity, and the theoretical utilization coefficient to obtain the first calculation coefficient of the new project; and determining the bus current of the new project based on the first total installed capacity of the new project and the first calculation coefficient of the new project.
[0014] This embodiment introduces a calibration step, which uses the total installed power of the new project and the historical project, as well as the theoretical utilization coefficient, to calibrate the historical calculation coefficients and obtain the first calculation coefficients specific to the new project. This solves the problem of model migration between projects of different sizes, enabling the selection results to adapt to the installed capacity of the new project and improving the model's generalization ability and accuracy.
[0015] In one embodiment, determining the bus current of the new project based on the first total installed capacity of the new project and the first calculation coefficient of the new project includes: calculating the initial bus current based on the first total installed capacity of the new project and the first calculation coefficient of the new project; obtaining the historical maximum bus current of historical projects corresponding to the equipment type; and determining the bus current of the new project based on the initial bus current and the historical maximum bus current.
[0016] In this embodiment, a verification step based on the calculated current and the historical maximum bus current is added. It not only relies on model calculations but also incorporates historical extreme values as a reference. This adds a safety redundancy to the selection results, provides a verification mechanism to prevent the model from underestimating risks, and further enhances the safety of the selection scheme.
[0017] In one embodiment, determining the bus current of the new project based on the initial bus current and the historical maximum bus current includes: obtaining the single-unit current of the new project based on the initial bus current and the number of units in the new project; obtaining the historical maximum single-unit current of the historical project based on the historical maximum bus current and the historical number of units in the historical project; comparing the single-unit current of the new project with the historical maximum single-unit current of the historical project, and determining the bus current of the new project from the initial bus current and the historical maximum bus current.
[0018] In one embodiment, comparing the single-unit current of the newly built project with the historical maximum single-unit current of the historical project, and determining the bus current of the newly built project from the initial bus current and the historical maximum bus current, includes: determining the initial bus current as the bus current of the newly built project if the single-unit current of the newly built project is greater than or equal to the historical maximum single-unit current; and determining the historical maximum bus current as the bus current of the newly built project if the single-unit current of the newly built project is less than the historical maximum single-unit current.
[0019] In this embodiment, the verification mechanism is specified as "unit current comparison" (i.e., single-unit current comparison), and based on this, it is determined whether to use the calculated current or the historical maximum current as the final result. This provides a more scientific and reasonable verification strategy. It takes into account differences in project scale, avoids the unfairness of simply comparing total current, and makes the verification logic more accurate.
[0020] In one embodiment, determining the bus parameters adapted to the new project based on the bus current includes: determining the bus parameters adapted to the new project based on the bus current and a preset relationship table between bus current and bus parameters.
[0021] This embodiment clarifies that the final busbar parameters are determined by querying a preset relationship table, thereby connecting the calculated current value with the standard busbar specifications in engineering practice. This completes the final step from theoretical calculation to physical selection, ensuring the feasibility and standardization of the solution.
[0022] Furthermore, to achieve the above objectives, this application also proposes a busbar parameter determination device, the device comprising: an acquisition module for the process of a new project; a processing module for determining the product type of the new project based on the process of the new project; determining the equipment type of the new project based on the product type of the new project; determining the electrical characteristic parameters of historical projects corresponding to the equipment type based on the equipment type of the new project; calculating the busbar current of the new project based on the first total installed power of the new project and the electrical characteristic parameters of historical projects corresponding to the equipment type; and determining busbar parameters adapted to the new project based on the busbar current, thereby determining a busbar adapted to the new project.
[0023] In addition, to achieve the above objectives, this application also proposes a bus parameter determination device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the bus parameter determination method as described above.
[0024] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the bus parameter determination method described above.
[0025] In addition, to achieve the above objectives, this application also provides a computer program product, which includes a computer program that, when executed by a processor, implements the steps of the bus parameter determination method described above. Attached Figure Description

[0043] In industrial power distribution design, the accuracy of busbar selection is crucial. Traditional methods rely mainly on the designer's experience, using fixed coefficients to estimate busbar current. However, this approach results in selections that are not applicable to new projects with different equipment types. Busbar selections often deviate from reality, either being overly conservative and wasting resources or overly risky and posing safety hazards.
[0044] To address this, this application proposes a method for determining bus parameters. The method includes: obtaining the process steps of a new project; determining the product type of the new project based on the process steps; determining the equipment type of the new project based on the product type; determining the electrical characteristic parameters of historical projects corresponding to the equipment type based on the equipment type; calculating the bus current of the new project based on the first total installed power of the new project and the electrical characteristic parameters of historical projects corresponding to the equipment type; and determining bus parameters suitable for the new project based on the bus current, thereby determining a bus suitable for the new project.
[0045] In this embodiment, the process of the new project is obtained, and then the equipment type of the new project is determined. Based on the equipment type of the new project, the electrical characteristic parameters of the historical projects of the corresponding equipment type are matched. Based on the first total installed power of the new project and the electrical characteristic parameters of the historical projects of the corresponding equipment type, the bus current of the new project is determined. This method of determining the bus current differently according to the equipment type overcomes the limitations of the traditional fixed coefficient method. It enables the bus parameters determined based on the bus current and the bus to accurately match the actual working conditions of the new project. This avoids the overload risk caused by under-selection and also avoids the investment waste and operating losses caused by over-selection.
[0046] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a desktop computer, tablet computer, personal computer, mobile phone, etc., or an electronic device capable of performing the above functions. The following description uses an electronic device as an example to illustrate this embodiment and the subsequent embodiments.
[0047] Based on the above, this application provides a method for determining busbar parameters, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the busbar parameter determination method of this application.
[0048] In this embodiment, the method for determining bus parameters includes steps S10 to S30:
[0049] Step S10: Obtain the work process of the newly created project.
[0050] Step S20: Determine the product type of the new project based on the process steps of the new project.
[0051] Step S30: Determine the equipment type of the new project based on the product type of the new project.
[0052] In the design of the power system for a factory, there are different processes, each with different conditions, and the selection of busbars also varies. The busbar parameter determination method proposed in this embodiment can be applied to the anode coating and infrared processes in battery manufacturing. The purpose of anode coating is to coat the current collector with anode active material to form an electrode sheet, and the purpose of infrared drying is to dry the electrode sheet using infrared technology.
[0053] Based on the different wire widths, the equipment used in the anode coating and infrared processes can be divided into two types: Type 1 (also known as wide-width) and Type 2 (also known as narrow-width). The wire widths of Type 1 and Type 2 equipment differ. Here, the wire width refers to the width of the coating head used for anode coating in the anode coating and infrared processes, which is also equal to the width of the coated electrode sheet (i.e., the width of the product produced by the equipment in this process).
[0054] The first type of equipment (also known as wide-width) has a wire width greater than a preset threshold, while the second type of equipment (also known as narrow-width) has a wire width less than the preset threshold. This preset threshold can be 1 meter. Specifically, the wire width of the first type of equipment (also known as wide-width) is 1.2 to 1.5 meters. Therefore, the width of the electrode sheet formed by coating with the first type of equipment (also known as wide-width) is approximately 1.2 to 1.5 meters, requiring the electrode sheet to be cut in the middle before being used to prepare the battery cell. The wire width of the second type of equipment (also known as narrow-width) is 0.5 to 0.8 meters. The width of the electrode sheet formed by coating with the second type of equipment (also known as narrow-width) is approximately 0.5 to 0.8 meters, requiring no cutting and can be directly used to prepare the battery cell.
[0055] Thus, when a new project needs to be established, the process steps of the new project can be obtained first. For example, the process steps of the new project can be determined as anodizing and infrared processes. Then, the product type of the new project under this process can be determined. For example, the product under the anodizing and infrared processes is an electrode sheet. Here, product type refers to the width category of the electrode sheet. For example, the width of the electrode sheet under the new anodizing and infrared processes is 1.2~1.5 meters or 0.5 meters~0.8 meters. After that, the equipment type of the new project can be determined according to the product type. For example, if the product type of the new project is an electrode sheet with a width of 1.2~1.5 meters, then the corresponding equipment wire width is at least 1.2~1.5 meters. According to the pre-set correspondence between the equipment wire width and the equipment type, the equipment type of the new project can be determined as the first equipment type (wide width). If the product type of the new project is an electrode sheet with a width of 0.5 meters~0.8 meters, then the corresponding equipment wire width is at least 0.5 meters~0.8 meters. According to the pre-set correspondence between the equipment wire width and the equipment type, the equipment type of the new project can be determined as the second equipment type (narrow width).
[0056] An example of equipment for anodic coating and infrared processes is shown in Table 1 below:
[0057] Table 1. Equipment Classification for Anodic Coating and Infrared Processes
[0058]
[0059] Step S40: Determine the electrical characteristic parameters of historical projects corresponding to the equipment type of the new project.
[0060] Before step S40, a first database and a second database are constructed based on the equipment type under the anodizing and infrared processes. The first database includes electrical characteristic parameters of one or more historical projects corresponding to wide-width equipment, and the second database includes electrical characteristic parameters of one or more historical projects corresponding to narrow-width equipment. Each historical project includes one or more wide / narrow-width devices.
[0061] After determining whether the equipment type of the target process in the new project is wide-width or narrow-width, if the equipment type of the target process in the new project is wide-width, the electrical characteristic parameters of historical projects of the corresponding equipment type are obtained from the pre-built first database; if the equipment type of the target process in the new project is narrow-width, the electrical characteristic parameters of historical projects of the corresponding equipment type are obtained from the pre-built second database.
[0062] Step S50: Calculate the bus current of the new project based on the first total installed capacity of the new project and the electrical characteristic parameters of historical projects of the corresponding equipment type.
[0063] Total installed capacity refers to the maximum theoretical output capacity of the entire power system under ideal conditions. The first total installed capacity of a new project is the sum of the rated power of all equipment under the target process of the new project. If the rated power of each piece of equipment under the target process of the new project is the same, the first total installed capacity = total number of equipment × rated power of a single piece of equipment.
[0064] The first total installed capacity of the new project, along with the electrical characteristic parameters of historical projects of the corresponding equipment type, are input into the preset calculation model to output the bus current of the new project.
[0065] Step S60: Determine the bus parameters that are compatible with the new project based on the bus current.
[0066] Based on the bus current of the new project, determine the bus parameters that are compatible with the new project, and thus determine the bus that is compatible with the new project.
[0067] Busbar parameters include, but are not limited to, the number of busbars, busbar capacity, and busbar material. Among these, busbar capacity refers to the maximum current a busbar can safely carry under specific conditions, and is a key parameter for measuring its power transmission capacity. Once the busbar parameters are determined, busbars suitable for the new project can be selected based on these parameters.
[0068] In one implementation, to avoid the risk of overload due to under-selection and to avoid the investment waste and operating losses caused by over-selection, the most suitable bus capacity with a load rate between 65% and 85% is usually selected.
[0069] Load factor = bus current / bus capacity (×100%), then bus capacity = bus current / load factor (65%~85%). For example, if the calculated bus current is 1850A, then the bus capacity is taken from 2176A~2846A.
[0070] In another implementation, a table relating bus current and bus parameters is pre-set. By consulting the pre-set table relating bus current and bus parameters based on the bus current of the new project, the bus parameters suitable for the new project can be determined, which simplifies the calculation process and improves processing efficiency.
[0071] The relationship between the preset bus current and bus parameters is shown in Table 2 below:
[0072] Table 2 Relationship between bus current and bus parameters
[0073]
[0074] It is worth noting that the table above is only an example; in practical applications, the data in the table can be designed according to needs.
[0075] In this embodiment, the process of the new project is obtained, and then the equipment type of the new project is determined. Based on the equipment type of the new project, the electrical characteristic parameters of the historical projects of the corresponding equipment type are matched. Based on the first total installed power of the new project and the electrical characteristic parameters of the historical projects of the corresponding equipment type, the bus current of the new project is determined. This method of determining the bus current differently according to the equipment type overcomes the limitations of the traditional fixed coefficient method. It enables the bus parameters determined based on the bus current and the bus to accurately match the actual working conditions of the new project. This avoids the overload risk caused by under-selection and also avoids the investment waste and operating losses caused by over-selection.
[0076] In one feasible implementation, the electrical characteristic parameters include: historical calculation coefficient and theoretical utilization coefficient. The historical calculation coefficient represents the proportion of the maximum measured power in historical projects to the total historical installed capacity, while the theoretical utilization coefficient represents the average utilization level of the equipment in historical projects.
[0077] When there are multiple historical projects, the historical calculation coefficient can be obtained by combining the measured maximum power of multiple historical projects and the total historical installed power, and the theoretical utilization coefficient can be obtained by combining the average usage level of multiple historical projects.
[0078] The historical calculation coefficient K0 for a historical project is a specific, retrospective observation that reflects the load characteristics of that historical project at a specific scale. However, new projects often differ from historical projects in terms of total installed capacity and number of units. Therefore, the historical calculation coefficient K0 cannot adapt to changes in the scale of new projects. To address this, this embodiment does not use the historical calculation coefficient K0 to predict the maximum power of the new project (maximum power can be converted to bus current). Instead, a new calculation model is designed. The input parameters of the new calculation model include: the first total installed capacity P1 of the new project, the historical calculation coefficient K0, and the theoretical utilization coefficient Kut'. Based on the new calculation model, the bus current I1 of the new project can be obtained adaptively.
[0079] Reference Figure 2 The above step S40 includes the following steps S401 and S405:
[0080] Step S401: Determine whether the equipment type of the new project is the first equipment type or the second equipment type. If the equipment type of the new project is the first equipment type, execute steps S402 and S403; if the equipment type of the new project is the second equipment type, execute steps S404 and S405.
[0081] Step S402: Determine the historical calculation coefficients based on the first preset value.
[0082] Step S403: Determine the theoretical utilization coefficient based on the historical calculated coefficient and the historical measured maximum coefficient of the corresponding equipment type.
[0083] Among them, the historical measured maximum coefficient Km represents the ratio of the historical project's measured maximum power to the measured average power. It describes the fluctuation and uncertainty of the load and serves as a "safety amplification factor" for dealing with peak loads.
[0084] In this embodiment, K0 is defined as Km × Kut`. By multiplying the two key factors, “average load level” (Kut`) and “load fluctuation range” (Km), a calculation coefficient that can scientifically and comprehensively predict the maximum power is obtained.
[0085] After obtaining the equipment type of the new project, if it is determined that the equipment type of the new project is the first equipment type (wide width), the first preset value and the historical measured maximum coefficient Km of the historical project are obtained from the first database. The first preset value is determined as the historical calculation coefficient K0, and the theoretical utilization coefficient Kut` is calculated based on the historical calculation coefficient K0 and the historical measured maximum coefficient Km. Specifically, Kut` = K0 / Km.
[0086] For wide-range equipment, the ratio of its "maximum power" to "average power" (i.e., Km) is not a simple fixed value. Therefore, in order to improve accuracy, the theoretical utilization coefficient Kut` is calculated by using the historical measured maximum coefficient Km and the historical calculated coefficient K0 obtained by dynamic calculation.
[0087] Step S404: Determine the historical calculation coefficients based on the first preset value.
[0088] Step S405: Determine the theoretical utilization coefficient based on the second preset value.
[0089] After obtaining the equipment type for the new project, if it is determined that the equipment type is the second equipment type (narrow width), the first preset value and the second preset value are retrieved from the second database. The first preset value is set as the historical calculation coefficient K0, and the second preset value is set as the theoretical utilization coefficient Kut`. The first preset value and the second preset value are different.
[0090] For narrow-range devices, their "maximum power" is very close to their "average power." This means that regardless of the number of devices, the ratio of their average power to their maximum power (Km) tends to a stable constant. Therefore, to reduce computational load and improve efficiency, a second preset value is used as the theoretical utilization factor Kut'.
[0091] For both narrow-width and wide-width devices, the historical calculation coefficients are not arbitrarily set. Instead, they are determined by analyzing data from a large number of historical projects, concluding that using a unified first preset value is sufficiently accurate for predicting the maximum power of historical projects of the corresponding wide / narrow-width types. Therefore, to incorporate this simplified experience into the calculation model, the first preset value is used to assign the historical calculation coefficient K0 for both wide-width and narrow-width devices.
[0092] The first preset value is 0.9 to 1.1, specifically 0.9, 1, 1.1, etc.; the second preset value is 0.6 to 0.65, specifically 0.6, 1 / 1.61, 0.65.
[0093] This embodiment defines the core components of electrical characteristic parameters (theoretical calculation coefficient K1, theoretical utilization coefficient Kut`) and clarifies the different strategies for wide-width and narrow-width devices in acquiring these parameters. Wide-width devices prioritize accuracy and use historical data for calculation, while narrow-width devices prioritize efficiency and use preset values for calculation. This achieves adaptability to different device types, balancing calculation efficiency and accuracy.
[0094] In one feasible implementation, refer to Figure 3 The historical measured maximum coefficient in step S403 above is obtained through the following steps S1 to S3:
[0095] Step S1: Obtain the historical total installed power, historical measured average power, and equivalent number of historical devices for the corresponding equipment type.
[0096] The total historical installed capacity of a historical project is the sum of the rated power of all equipment under the historical project's processes. If the rated power of each piece of equipment under the historical project's processes is the same, then the total historical installed capacity = the total number of historical equipment × the rated power of a single historical piece of equipment. Assuming the total historical installed capacity is P0, the total number of historical equipment is N, and the rated power of a single historical piece of equipment is Pe0, then P0 = N × Pe0.
[0097] The historical measured average power is the sum of the active average power of all equipment under the process of the historical project, which can be obtained through actual measurement. The historical measured average power is represented by Pav.
[0098] The equivalent number of historical equipment units is the actual group of electrical equipment with different power and operating modes under each process of the historical project, denoted by n. eq express.
[0099] In this embodiment, three data points of a similar historical project are retrieved from the historical database: historical total installed power P0, historical measured average power Pav, and equivalent number of historical devices n. eq .
[0100] Step S2: Calculate the historical measured utilization factor based on the historical total installed power and the historical measured average power.
[0101] The historical measured utilization factor characterizes the average utilization level of equipment in a single historical project and can be represented by Kut. When there is only one historical project, the theoretical utilization factor Kut' is the same as the historical measured utilization factor Kut; however, when there are multiple historical projects, the theoretical utilization factor Kut' often differs from the historical measured utilization factor Kut.
[0102] For a historical project, the historical measured utilization factor Kut = historical measured average power Pav ÷ historical total installed power P0, that is, Kut = Pav / P0.
[0103] Step S3: Determine the maximum historical measured coefficient based on the historical measured utilization coefficient and the equivalent number of historical equipment units.
[0104] Based on the historical measured utilization coefficient Kut and the equivalent number of historical equipment n of the historical project eq By querying the existing "Maximum Coefficient Km Table", the historical measured maximum coefficient (Km) of this historical project can be obtained.
[0105] It is worth noting that steps S1 to S3 can be executed before step S40 in this embodiment and updated periodically, or updated in real time according to changes in historical projects. In the case of new projects, there is no need for real-time calculation, thereby improving calculation efficiency.
[0106] This embodiment specifically defines the steps for obtaining the historical measured maximum coefficient Km of wide-span equipment. Specifically, it calculates the historical measured utilization coefficient using the historical total installed power and the historical measured average power, and then determines Km by combining this with the equivalent number of historical equipment units. This establishes a reliable Km value determination process based on historical measured data for wide-span equipment, laying the foundation for accurate calculations.
[0107] In one feasible implementation, when there are multiple historical projects for the corresponding equipment type, there are multiple historical measured utilization coefficients and multiple equivalent number of historical equipment.
[0108] Step S3 above includes: sorting multiple historical measured utilization coefficients in descending order, removing some data at both ends, and taking the maximum value among the remaining data as the standard utilization coefficient; sorting multiple historical equivalent numbers of equipment in descending order, removing some data at both ends, and taking the maximum value among the remaining data as the standard equivalent number of equipment; and determining the maximum historical measured coefficient based on the standard utilization coefficient and the standard equivalent number of equipment.
[0109] If there is only one historical project corresponding to the width type, a historical measured utilization coefficient Kut can be obtained based on this historical project as the theoretical utilization coefficient Kut`, and an equivalent number n of historical equipment can be obtained based on this historical project. eq Subsequently, based on the historical measured utilization factor Kut and the equivalent number of historical devices n for this historical project... eq By querying the existing "Maximum Coefficient Km Table", the historical measured maximum coefficient (Km) of this historical project can be obtained.
[0110] When there are multiple historical projects of the corresponding width type, a historical measured utilization coefficient Kut and an equivalent number of historical devices n can be obtained for each historical project. eq This allows us to obtain multiple historical measured utilization coefficients and multiple equivalent number of historical devices.
[0111] At this point, the multiple historical measured utilization coefficients Kut are sorted in descending or ascending order. After removing the data at both ends of the sequence, the maximum value among the remaining data is taken as the standard utilization coefficient K. ut_新 And the equivalent number n of multiple historical devices. eq Sort the data in descending or ascending order, remove the data at both ends of the sequence, and take the maximum value among the remaining data as the equivalent number of standard equipment units, n.eq_新 Then, based on the equivalent number K of standard equipment... ut_新 Equivalent number of units n to standard equipment eq_新 By querying the existing "Maximum Coefficient Km Table", the historical measured maximum coefficient Km of this historical project can be obtained.
[0112] It's worth noting that removing the maximum and minimum values can be done by removing just one maximum and one minimum value, or by sorting multiple values and removing the top 20% and bottom 20% of the maximum and minimum values. For example: Suppose there are 10 similar wide-width historical projects, resulting in 10 historical measured utilization coefficients (Kut) and 10 historical equivalent equipment counts (n). eq Sort the 10 Kut values, remove the two smallest (20%) and two largest (20%) values, and take the maximum value from the remaining 6 data. Use this value as the standard utilization coefficient Kut_new to determine the historical measured maximum coefficient (Km).
[0113] Similarly, for 10 n... eq The values are sorted, and the smallest and largest 20% of the data are removed. The maximum value in the remaining data is taken as the standard equivalent number n of equipment used to determine the historical maximum measured coefficient (Km). eq_新 .
[0114] In this embodiment, a data cleaning and optimization method (e.g., the 80% probability maximum value method) is proposed for multiple historical projects. By removing extreme values and taking the maximum, the "standard utilization coefficient" and "equivalent number of standard equipment" are obtained, which are used to determine the final historical measured maximum coefficient. This eliminates abnormal interference in historical data, making the benchmark parameters used for calculation more representative and robust, and improving the reliability of the selection.
[0115] In one feasible implementation, the electrical characteristic parameters include: historical total installed capacity P0, historical calculation coefficient K0, and theoretical utilization coefficient Kut`.
[0116] The inputs to the preset calculation model in this embodiment include: the first total installed power P1 of the new project, and electrical characteristic parameters of historical projects with the same equipment type as the new project: historical total installed power P0, historical calculation coefficient K0, and theoretical utilization coefficient Kut`. Inputting these data into the preset calculation model will output the bus current of the new project. The calculation process of the preset calculation model is explained below. (Refer to...) Figure 4 The above step S50 includes the following steps S501 and S502.
[0117] Step S501: Based on the first total installed capacity of the new project, the historical total installed capacity, and the theoretical utilization coefficient, the historical calculation coefficient is calibrated to obtain the first calculation coefficient of the new project.
[0118] Step S502: Determine the bus current of the new project based on the first total installed capacity of the new project and the first calculation coefficient of the new project.
[0119] In this embodiment, the historical calculation coefficient K0 cannot adapt to changes in the scale of the new project. Therefore, it is not used to predict the maximum power of the new project. Instead, a calibration step is introduced. Based on the first total installed power P1 of the new project, the historical total installed power P0, and the theoretical utilization factor Kut', the historical calculation coefficient K0 is calibrated to obtain the first calculation coefficient K1 of the new project. Then, based on the calibrated first calculation coefficient K1 and the first total installed power P1 of the new project, the maximum power Pmax1 of the new project is calculated, where Pmax1 = P1 × K1. Finally, based on the maximum power Pmax1, voltage U, and power factor of the new project... The bus current I1 of the new project is calculated.
[0120] In this embodiment, a calibration coefficient Kj is introduced for calibration, so K1 = K0 × Kj. The calibration coefficient Kj can be obtained by the following formula (1):
[0121] (1)
[0122] Therefore, the first calculation coefficient K1 of the new project can be obtained by the following formula (2):
[0123] (2)
[0124] Thus, assuming the bus current of the new project is represented by I1, it can be obtained through the following formula (3):
[0125] (3)
[0126] The preset calculation model can be obtained according to formulas (2) and (3). It can be seen that the inputs to the preset calculation model are the first total installed power P1 of the new project, the historical total installed power P0, the theoretical utilization coefficient Kut`, and the historical calculation coefficient K0; the output of the preset calculation model is the bus current I1 of the new project; and the first calculation coefficient K1 of the new project is an intermediate value, which can be selected to be output or not output as needed. Voltage U and power factor The voltage U is a constant, and the power factor can be 0.39. It can be 0.93.
[0127] This embodiment introduces a calibration step, which uses the total installed power of the new project and the historical project, as well as the theoretical utilization coefficient, to calibrate the historical calculation coefficients and obtain the first calculation coefficients specific to the new project. This solves the problem of model migration between projects of different sizes, enabling the selection results to adapt to the installed capacity of the new project and improving the model's generalization ability and accuracy.
[0128] In another feasible implementation, refer to Figure 5 The above step S502 includes the following steps S5021 and S5023.
[0129] Step S5021: Calculate the initial bus current based on the first total installed capacity of the new project and the first calculation coefficient of the new project.
[0130] In this embodiment, based on the first total installed power P1 of the new project and the first calculation coefficient K1 of the new project, the bus current I1 of the new project is not directly obtained, but the initial bus current I_initial is obtained, which can be shown by the following formula (4):
[0131] (4)
[0132] Step S5022: Obtain the historical maximum bus current of the historical items for the corresponding equipment type.
[0133] Step S5023: Determine the bus current of the new project based on the initial bus current and the historical maximum bus current.
[0134] This embodiment adds a verification step to the above embodiment. After calculating the initial bus current I_initial, it retrieves the historical maximum bus current I_max measured from similar projects from either the first or second database. I_initial is then compared with I_max to finally determine the bus current I1 for the new project used in the selection process.
[0135] In this embodiment, a verification step based on the calculated current and the historical maximum bus current is added. It not only relies on model calculations but also incorporates historical extreme values as a reference. This adds a safety redundancy to the selection results, provides a verification mechanism to prevent the model from underestimating risks, and further enhances the safety of the selection scheme.
[0136] In another feasible implementation, the method for comparing I_initial and I_max to ultimately determine the implementation of the bus current I1 for the new project used in the selection is explained. (Refer to...) Figure 6 Step S5023 includes the following steps S5023-1 to S5023-5.
[0137] Step S5023-1: Obtain the per-unit current of the new project based on the initial bus current and the number of equipment in the new project.
[0138] Based on the initial bus current I_initial and the number of equipment n in the new project, obtain the per-unit current I_initial / n of the new project.
[0139] Step S5023-2: Obtain the historical maximum per-unit current of the historical project based on the historical maximum bus current and the historical number of equipment in the historical project.
[0140] Based on the historical maximum bus current I_max and the historical number of equipment N in the historical project, obtain the historical maximum per-unit current I_max / N of the historical project.
[0141] Step S5023-3: Determine whether the per-unit current of the new project is less than the historical maximum per-unit current. If the determination is yes, execute Step S5023-4; if the determination is no, execute Step S5023-5.
[0142] Step S5023-4: Determine the historical maximum bus current as the bus current of the new project.
[0143] When the per-unit current I_initial / n of the new project < the historical maximum per-unit current I_max / N, that is, I_initial / n < I_max / N, it indicates that the calculation result of the new project may be underestimated and the verification fails. Determine the historical maximum per-unit current I_max / N as the bus current I1 of the new project.
[0144] Step S5023-5: Determine the initial bus current as the bus current of the new project.
[0145] When the per-unit current I_initial / n of the new project ≥ the historical maximum per-unit current I_max / N, that is, I_initial / n ≥ I_max / N, it indicates that the per-unit current of the new project has covered the historical extreme value and the verification passes. Determine the initial bus current I_initial of the new project as the bus current I1 of the new project.
[0146] In this embodiment, the verification mechanism is specifically implemented as "per-unit current comparison" (i.e., per-unit current comparison), and based on this, it is decided whether to use the calculated current or the historical maximum current as the final result. Thus, a more scientific and reasonable verification strategy is provided. It takes into account the differences in project scale, avoids the unfairness of simply comparing the total current, and makes the verification logic more accurate.
[0147] The following provides an overall example description of the method for determining bus parameters of the present application in combination with the above embodiments.
[0148] Collect electrical characteristic parameters of historical projects, including the historical total installed capacity P0, historical measured average power Pav, and the equivalent number of historical devices n for each project. eq Then, based on the historical measured utilization factor Kut = historical measured average power Pav ÷ historical total installed power P0, i.e. Kut = Pav / P0, the historical measured utilization factor Kut for each project can be calculated.
[0149] If there is only one historical project, then the historical measured utilization factor Kut = the theoretical utilization factor Kut`. This is based on the theoretical utilization factor Kut` and the equivalent number of historical devices n. eq By querying the existing "Maximum Coefficient Km Table", the historical measured maximum coefficient Km for this historical project can be obtained.
[0150] If there are multiple historical projects, then based on the historical measured utilization coefficients Kut of multiple projects, the maximum and minimum values of 20% are removed, and the maximum value among the remaining data is taken as the standard utilization coefficient Kut_new; based on the equivalent number of historical equipment n of multiple projects... eq After removing 20% of the maximum and 20% of the minimum values, the maximum value among the remaining data is taken as the equivalent number of standard equipment units, n. eq_新 By querying the existing "Maximum Coefficient Km Table", the historical measured maximum coefficient Km for this historical project can be obtained.
[0151] After obtaining the historical measured maximum coefficient Km of the historical project, according to the definition of K0=Km×Kut` in this embodiment, by multiplying the two key factors of "average load level" (Kut`) and "load fluctuation amplitude" (Km), a calculation coefficient that can scientifically and comprehensively predict the maximum power is obtained.
[0152] In this embodiment, the historical calculation coefficient K0 = Km × Kut` for historical projects can predict the maximum power. Since the historical calculation coefficient K0 = Km × Kut` is a user-defined calculation coefficient used to predict the maximum power, the accuracy of the historical calculation coefficient K0 needs to be verified.
[0153] The verification process includes: applying the calculated historical calculation coefficient K0 to a certain historical wide-width project, and calculating the predicted maximum power Pmax0 = historical total installed power P1 × historical calculation coefficient K0, that is, Pmax0 = P1 × K0, to obtain Pmax0. Then, compare the predicted maximum power Pmax0 with the historical measured maximum power Pmax_history of this historical project. If the predicted maximum power Pmax0 ≥ Pmax_history, the verification passes. The obtained historical calculation coefficient K0 and the theoretical utilization coefficient Kut` can be used to predict the bus current of a new project. If the predicted maximum power Pmax0 < Pmax_history, the verification fails. At this time, a new Km value can be calculated inversely using the formula Km_correction = Pmax_history (the historical measured maximum power of this historical project) / Pav (the historical measured average power of this historical project) to correct the parameters of this historical project.
[0154] Thus, in the case of calculating a new wide-width project, assuming the total installed power of the new project is P_new, the maximum power of the new project P1_calculated = P_new × K0 is calculated using the historical calculation coefficient K0. Combining parameters such as the power factor, the bus current Ij = P1_calculated / ( × U × ) = (P_new × K0) / ( × U × )。
[0155] However, after selecting the type according to the bus current Ij calculated in the above manner, the selected bus capacity is not suitable for the new wide-width project. This is because the historical calculation coefficient K0 cannot adapt to the change in the scale of the new project. Therefore, in this embodiment, the historical calculation coefficient K0 is not directly used to predict the maximum power of the new project.
[0156] This is because in the bus selection, the purpose of the historical calculation coefficient K0 is to accurately predict the maximum power demand. Even if the average utilization rate (characterized by Kut`) is the same, the change in the scale (number of equipment or installed power) of the new project will affect the fluctuating power, thus requiring different calculation coefficients.
[0157] In this embodiment, the calculation coefficient K1 of the new project is directly calculated, and the specific process is as follows:
[0158] The maximum power of the new project P1_calculated = the first total installed power P1 of the new project × the calculation coefficient K1 of the new project, that is, P1_calculated = P1 × K1.
[0159] Since the maximum power P1 of the new project is calculated as the average power Pav1 of the new project plus the fluctuating power Pb1 of the new project, that is, P1_calculated = Pav1 + Pb1. Where, the average power Pav1 of the new project = P1 × Kut`, where Kut` is the theoretical utilization factor; the fluctuating power Pb1 of the new project = a × n is the number of devices in the new project, and a is a constant.
[0160] Since P1_calculation = P1 × K1 = Pav1 + Pb1, therefore, K1 = (Pav1 + Pb1) / P1. Substituting Pav1 = P1 × Kut' into the equation, we get K1 = (P1 × Kut' + Pb1) / P1. Therefore, Pb1 = a × Substituting, we get K1 = (P1 × Kut` + a × ) / P2.
[0161] Since each piece of equipment on the same type of production line has the same rated power, the historical total installed power P0 of historical projects = the number of historical equipment N × rated power P, and the first total installed power P1 of new projects = the number of equipment in the new project n × rated power P. Therefore, we can get P0 / P1 = N / n, then n = (P1 × N) / P0. Substituting this into the formula for K1 above, we get K1 = (P1 × Kut` + a × ) / P1, thus obtaining K1=(P1×Kut`+a× ) / P1, due to the historical project's fluctuating power Pb0=a× Substituting this into the formula for K1, we get K1 = (P1 × Kut` + Pb0 × ) / P1.
[0162] For the same reason, the maximum power of the historical project P0_calculation = the total installed power of the historical project P0 × the calculation coefficient of the historical project K0, that is, P0_calculation = P0 × K0.
[0163] Since the maximum power P0 of historical projects is calculated as the average power Pav0 of historical projects plus the fluctuating power Pb0 of historical projects, the calculation of P0 is Pav0 + Pb0. Where the average power Pav0 of historical projects is P0 × Kut', and Kut' is the theoretical utilization factor; the fluctuating power Pb0 of new projects is a × N represents the number of devices in the historical projects, and a is a constant.
[0164] Based on this, we can derive P0 × K0 = P0 × Kut' + Pb0. Therefore, Pb0 = P0 × K0 - P0 × Kut', that is, Pb0 = P0 × (K0 - Kut'). Substituting this into the formula for K1 above, we get K1 = (P1 × Kut' + P0 × (K0 - Kut') × ... ) / P1.
[0165] It is worth noting that, because the fluctuating power is related to the square root of the number of devices, the calculation factor K0 for historical projects differs from that for newly constructed projects. This explains, from a theoretical perspective, the fundamental reason why the calculation factors for historical projects and newly constructed projects differ.
[0166] In this embodiment, the calibration coefficient Kj is defined as K1 / K0, then Kj = (P1×Kut` + P0×(K0-Kut`)× ) / (P1×K0)。
[0167] Based on this, the bus current I1 of the new project is I1 = (K0 × Kj) / ( ×U× ).
[0168] It is worth noting that since Kut` represents the average equipment utilization rate, and the average equipment utilization rate of new projects is the same as that of historical projects, the average power of new projects is Pav1 = P1 × Kut`, and the average power of historical projects is Pav0 = P0 × Kut`.
[0169] Based on the above reasoning process, the preset calculation model in this embodiment is I1 = (K0 × Kj) / ( ×U× ), where Kj = (P1 × Kut` + P0 × (K0 - Kut`) × ) / (P1×K0)。
[0170] When designing the busbar type for a new project, first obtain the parameters P1, P0, Kut`, and K0, where P0, Kut`, and K0 are electrical characteristic parameters of historical projects. Then, substitute these parameters into the preset calculation model to obtain the busbar type I1 for the new project.
[0171] However, in the anodic coating and infrared processes, the equipment can be divided into two categories, "wide" and "narrow," based on the different wire widths. Therefore, the electrical characteristic parameters P0, Kut`, and K0 are obtained for both wide and narrow equipment, and the bus current of the corresponding new project with the appropriate width or narrow wire width is obtained according to the preset calculation model.
[0172] After analyzing a large number of historical wide and narrow format projects, the inventors found that the calculated coefficient K0 values for both wide and narrow format devices hovered around 1, while the maximum coefficient Km value for narrow format projects hovered around 1.61. However, the maximum coefficient Km value for wide format devices varied significantly. Therefore, to balance computational efficiency and accuracy, this embodiment sets 1 as the first preset value and 1 / 1.61 as the second preset value. When a new project is wide format, K0=1, and Kut` is obtained from historical data; when a new project is narrow format, K0=1, Km=1.61, and Kut`=1 / 1.61. The Kut` value for historical wide format projects is updated periodically or in real-time based on changes in historical projects.
