Description

Technical Field

[0001] The present invention belongs to the technical field of power marketing management, and in particular relates to a power marketing method and system based on an intelligent management platform. Background Art

[0002] In the current power marketing field, power companies usually develop targeted power supply plans based on the different needs of enterprises, especially in work processes involving key equipment, which often require different power supports at different process stages. Existing technologies mainly rely on providing corresponding current and voltage supplies for key equipment in specific periods of time based on historical data and equipment operation rules. Typically, the marketing strategy of power companies focuses on providing sufficient current when equipment is running at high load to ensure smooth production. However, this approach may not be able to fully cope with changes in power demand of equipment in actual operation when faced with complex processes and precision equipment, especially in multi-step complex processes, where fluctuations in current and voltage may have a profound impact on production.

[0003] However, a major drawback of the prior art is that it cannot intelligently determine whether power fluctuations are associated with the execution of complex process stages. In traditional power marketing schemes, power fluctuations are usually treated as isolated events, and the fact that fluctuations may be closely related to process steps is not fully considered. This leads to insufficient or excessive power supply at certain critical moments, which in turn affects the stability of the equipment and production quality. In addition, the prior art usually adopts a current-first approach to power optimization, that is, when power fluctuations occur, compensation is first performed by increasing or decreasing the current, ignoring the fundamental role of voltage in the entire power system. This approach can easily lead to equipment overload, waste of power resources, and even equipment damage in complex processes.

[0004] Therefore, the existing technology has obvious deficiencies, which are mainly reflected in the inability to accurately identify the relationship between power fluctuations and complex processes, and over-reliance on current adjustment during power optimization, ignoring the importance of voltage. This deficiency makes the equipment vulnerable to power fluctuations during operation, resulting in reduced production efficiency, unstable product quality, and even irreversible damage to the equipment. In response to these problems, a power marketing method based on an intelligent management platform is proposed, which can scientifically analyze the abnormal conditions of equipment during current fluctuations and give priority to voltage optimization, thereby providing more accurate and stable power support for complex process steps.

At the same time, referring to the electrical tolerance range provided by the equipment manufacturer, a voltage change amplitude that can ensure stable operation of the target core equipment and does not affect the process quality is determined as the preset amplitude after comprehensive evaluation.

[0013] As a further limitation of the technical solution of the embodiment of the present invention, the abnormal fluctuation period analysis module specifically includes: An abnormal fluctuation period determination unit, configured to determine that if it is determined that multiple current fluctuation curves all have a situation where the current changes frequently within the same period, the time period is an abnormal fluctuation period; A data search unit is used to retrieve a process flow chart of a target core device in a target processing process, and search the process flow chart for work content corresponding to an abnormal fluctuation period; The specific process step judgment unit is used to analyze whether the work content corresponding to the abnormal fluctuation period contains a specific process step composed of multiple subdivided process actions, so as to confirm whether the target core equipment has performed the specific process step during the abnormal fluctuation period.

[0018] In addition, this method follows the principle of voltage priority when providing power optimization strategies for each detailed action of complex processes. By combining the amplitude of voltage and current changes, the system can dynamically adjust the voltage or current supply to ensure that the equipment always maintains the best operating state during key process steps. This method not only improves the operating stability and production efficiency of the equipment, but also effectively reduces process defects caused by power fluctuations and ensures the high-precision execution of complex processes.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0022] Specifically, a power marketing method based on an intelligent management platform comprises the following steps: Step S100, obtaining current fluctuation curves of the target core device after completing the target processing flow for several times, interpreting these current fluctuation curves in sequence, and determining whether these current fluctuation curves all have frequent current changes in the same processing period.

[0023] The situation where the current changes frequently refers to the situation where the number of changes in the current exceeds a preset threshold within a preset time period.

[0024] In the embodiment of the present invention, the target core equipment can be key equipment in the industrial field, such as an arc furnace in a steel plant, a reactor in a chemical plant, or a CNC machine tool in the manufacturing industry. These devices have extremely high requirements for power supply during operation, and the stability of the current directly affects production efficiency and product quality. The current fluctuation curve is collected in real time through the smart meter and sensor on the equipment, recording the current changes of the equipment in different process steps, and generating a fluctuation curve for analysis.

[0025] The preset threshold value not only defines the maximum allowable current change amplitude, but also specifies the maximum number of current changes within the preset time period. When the number of current fluctuations exceeds the preset threshold, it may cause unstable equipment operation, affect the continuity of the production process and product quality, and indicate that the current and voltage matching within the time period is unreasonable. This unreasonable current and voltage matching may cause the equipment to be inefficient or have a reduced quality in key process steps, and timely adjustments are required to ensure the stability of the production process.

[0026] Furthermore, the power marketing method based on the intelligent management platform also includes the following steps: Step S200, if it is determined that multiple current fluctuation curves have frequent current changes in the same time period, determine the abnormal fluctuation period of the frequent current changes, and judge whether the target core device has performed a specific process step consisting of multiple subdivided process actions during the abnormal fluctuation period.

[0027] Specifically, Figure 2 A flow chart for determining whether a target core device has performed a specific process step during an abnormal fluctuation period is shown.

[0028] If it is determined that multiple current fluctuation curves have frequent current changes in the same period, determining the abnormal fluctuation period of the frequent current changes, and judging whether the target core equipment has performed a specific process step consisting of multiple subdivided process actions in the abnormal fluctuation period specifically includes the following steps: Step S201, if it is determined that multiple current fluctuation curves have frequent current changes in the same period, determine that the time period is an abnormal fluctuation period; Step S202, retrieve the process flow table of the target core equipment in the target processing process, and search the process flow table for the work content corresponding to the abnormal fluctuation period; Step S203 , analyzing whether the work content corresponding to the abnormal fluctuation period includes a specific process step composed of multiple subdivided process actions, so as to confirm whether the target core equipment has performed the specific process step during the abnormal fluctuation period.

[0029] In an embodiment of the present invention, the interception of the abnormal fluctuation period is based on the analysis of multiple current fluctuation curves. When different current fluctuation curves show frequent changes in current within the same period, that is, when the number of changes in current within a preset time period exceeds a preset threshold, the time period is identified as an abnormal fluctuation period. Specifically, this period usually covers multiple adjacent time points, and the current fluctuation amplitude and frequency are large, indicating that there is a problem with the matching of power supply and equipment operation. The intercepted abnormal fluctuation period will be used to further analyze the operating status and process steps of the equipment.

[0030] The process flow chart is usually prepared by process engineers or production managers, recording the operation sequence of each step of the equipment when executing the target processing flow, the required time, the equipment parameters involved (such as current and voltage requirements), and the specific requirements of each process step. The basis for formulating the process flow chart includes the equipment operation manual, process specifications, production experience and historical data. The method of obtaining the process flow chart usually includes retrieving it from the company's production management system or MES (manufacturing execution system), or it can be obtained by directly communicating with the equipment operator or process engineer.

[0031] Specific process steps refer to key steps in the target processing flow that are composed of multiple subdivided process actions. These steps usually have a significant impact on product quality and production efficiency, and may involve complex operations. For example, in steel production, specific process steps may include a combination of heating, rolling, and cooling; in chemical production, it may involve the coordination of multiple reactions and separation steps; in CNC machine tool operations in the manufacturing industry, specific process steps may contain cycles of precision machining, measurement, and adjustment. Analyzing these steps can help determine the operating status of equipment during periods of abnormal fluctuations, thereby optimizing power supply and process flow.

[0032] Furthermore, the power marketing method based on the intelligent management platform also includes the following steps: Step S300, if it is determined that the target core device has performed a specific process step during the abnormal fluctuation period, the fluctuation points of the current fluctuation curve in the abnormal fluctuation period are matched with corresponding subdivided process actions, and the voltage change amplitude of the target core device is obtained when the subdivided process action matched by each fluctuation point is performed.

[0033] Specifically, Figure 3 A flow chart is shown for obtaining the voltage variation amplitude of the target core device when the segmented process action matching each fluctuation point is performed.

[0034] Among them, if it is determined that the target core device has performed a specific process step during the abnormal fluctuation period, matching the fluctuation points of the current fluctuation curve in the abnormal fluctuation period with corresponding subdivided process actions, and obtaining the voltage change amplitude of the target core device when the subdivided process actions matched by each fluctuation point are in progress specifically include the following steps: Step S301, if it is determined that the target core device has performed a specific process step within the abnormal fluctuation period, determine the specific occurrence time of each fluctuation point of the current fluctuation curve within the abnormal fluctuation period; Step S302, according to the actual execution time of each subdivided process action in the specific process step, these actual execution times are matched with the specific occurrence time of the fluctuation point in the abnormal fluctuation period to identify the subdivided process action corresponding to each fluctuation point; Step S303, obtaining the voltage variation amplitude of the target core device when the subdivided process action matching each fluctuation point is performed.

[0035] In the embodiment of the present invention, the specific occurrence time of each fluctuation point in the abnormal fluctuation period is determined by analyzing the current fluctuation curve. These moments mark the moments when the current fluctuates significantly during the operation process. For example, assuming that in a certain production process, the current fluctuates significantly at 5 seconds, 10 seconds and 15 seconds, these time points will be recorded as the specific occurrence time of the fluctuation point.

[0036] The actual execution time of each subdivided process action in a specific process step is matched with the previously determined fluctuation point occurrence time. Assuming that a subdivided process action is performed between the 6th and 8th seconds, if the fluctuation point occurs at the 7th second, this fluctuation point is matched with the subdivided process action, thereby identifying which process action is related to the current fluctuation.

[0037] Once the fluctuation points are matched with the corresponding subdivided process actions, the voltage change amplitude during these process actions can be obtained. The voltage change amplitude can be monitored in real time by sensors on the equipment, recording the difference between the voltage level during the process action and the normal level. For example, if the voltage drops from the standard 220V to 210V during the execution of a process action, the voltage change amplitude is 10V.

[0038] Furthermore, the power marketing method based on the intelligent management platform also includes the following steps: Step S400, determining the current variation amplitude of each fluctuation point according to the local curve of the current fluctuation curve of the target core device during the abnormal fluctuation period, and providing a power optimization strategy for each fluctuation point according to the current variation amplitude and voltage variation amplitude corresponding to each fluctuation point.

[0039] Specifically, Figure 4 A flow chart is shown for comprehensively providing a power optimization strategy for each fluctuation point based on the current variation amplitude and voltage variation amplitude corresponding to each fluctuation point.

[0040] Among them, according to the local curve of the current fluctuation curve of the target core equipment during the abnormal fluctuation period, the current change amplitude of each fluctuation point is determined, and according to the current change amplitude and voltage change amplitude corresponding to each fluctuation point, a power optimization strategy is comprehensively provided for each fluctuation point, which specifically includes the following steps: Step S401, for each fluctuation point, checking whether the voltage variation amplitude of the target core device exceeds a preset amplitude when the subdivided process action matched thereto is performed; Step S402, if the voltage variation amplitude of the target core device when a subdivided process action matching a certain fluctuation point is performed is greater than a preset amplitude, then the voltage supply of the target core device when the subdivided process action matching the fluctuation point is performed is optimized according to the voltage variation amplitude corresponding to the fluctuation point; Step S403, if the voltage change amplitude of the target core device when a segmented process action matching a certain fluctuation point is performed is not greater than a preset amplitude, then the current change amplitude of the fluctuation point is determined based on the local curve of the current fluctuation curve of the target core device during the abnormal fluctuation period, and the current supply of the target core device when performing the segmented process action matching the fluctuation point is optimized based on the current change amplitude corresponding to the fluctuation point.

[0041] The preset amplitude is set based on the electrical characteristics and process requirements of the target core equipment, combined with historical operating data and the technical specifications of the equipment manufacturer. Specifically, the voltage and current requirements of the target core equipment in different process steps are taken into consideration, and the impact of voltage fluctuations in historical data on the performance and product quality of the target core equipment is analyzed. At the same time, the electrical tolerance range provided by the equipment manufacturer is referenced. After comprehensive evaluation, a voltage change amplitude that can ensure the stable operation of the target core equipment and does not affect the process quality is determined as the preset amplitude.

[0042] In an embodiment of the present invention, an example is given: it is assumed that a high-precision etching equipment (target core equipment) is managed in a semiconductor manufacturing plant. During operation, a certain subdivided process action of the equipment is a precision etching stage, which requires a very stable voltage, and the preset voltage change amplitude is ±5V. In step S401, it is analyzed that at a certain fluctuation point in the precision etching period, the voltage dropped from 220V to 213V, with a change amplitude of 7V, exceeding the preset ±5V threshold. In order to optimize the voltage supply, the voltage can be adjusted back to 220V by increasing the output of the voltage regulator during this fluctuation point, ensuring that the equipment maintains voltage stability in this critical process step, reducing the impact of voltage fluctuations on etching accuracy, and thus avoiding product quality problems.

[0043] If in another subdivided process action of the same device, such as the heating stage, the voltage variation is only 3V (between 220V and 217V), which does not exceed the preset ±5V threshold, then there is no need to optimize the voltage. Then according to step S403, further analysis found that the current fluctuation in this process step is large, and the variation reaches ±15A. In order to optimize the current supply, the current controller can be adjusted during this fluctuation point to stabilize the current supply within the range required by the device (for example, from the fluctuating ±15A to ±5A), ensuring that the heating process is stable, thereby avoiding the problem of uneven heating caused by excessive current fluctuations.

[0044] Prioritizing voltage optimization can enhance the overall stability of the system compared to directly optimizing current supply. Voltage, as a basic parameter of the power system, is crucial to the stability of the entire network. By prioritizing voltage adjustment and stabilization, system-wide instability can be effectively reduced, equipment failures or performance degradation caused by voltage fluctuations can be avoided, and the reliable operation of the entire power system can be ensured.

[0045] In addition, voltage optimization can better protect equipment and improve energy efficiency. Voltage fluctuations will impose additional electrical stress on the internal components of the equipment, which may cause component damage and shorten the service life. Maintaining voltage stability can extend the service life of the equipment and reduce maintenance costs. At the same time, by reducing unnecessary voltage fluctuations, it can improve the efficiency of power utilization, ensure that the equipment operates at the optimal energy efficiency point, and reduce energy waste.

[0046] The entry point of this technical solution in practical application can be in high-precision manufacturing or industries that require a highly stable power supply. For example, in semiconductor manufacturing, precision machining, or chemical reaction control, the equipment has very high requirements for voltage stability. By prioritizing voltage optimization, it can ensure that these high-demand processes operate in a stable power environment, reducing process quality problems and equipment damage caused by voltage fluctuations. In addition, for key equipment in large industrial parks, by prioritizing voltage optimization, the stability and reliability of the overall power system can also be improved, thereby reducing large-scale power failures.

[0047] For fields with complex and precise process steps, such as semiconductor manufacturing, precision machining or chemical reaction control, the strategy of prioritizing voltage optimization and combining current supply adjustment is particularly critical. The equipment in these fields has extremely high requirements for the stability and accuracy of power supply. Any slight fluctuation in voltage or current may have a significant impact on the process results. Through this refined power management solution, power companies can ensure that equipment has stable power support in each key step to avoid production defects or quality problems caused by power fluctuations.

[0048] This method can not only ensure the continuity and reliability of complex processes, but also significantly reduce equipment failure rate and maintenance costs, extend equipment life, and thus improve overall production efficiency. For industries that require highly precise operations, this is an important means to ensure product quality, improve customer satisfaction, and maintain competitive advantage.

[0049] Furthermore, Figure 5 The application architecture diagram of the system provided by the embodiment of the present invention is shown.

[0050] Among them, in another preferred embodiment provided by the present invention, a power marketing system based on an intelligent management platform includes: The current frequent change identification module 100 is used to obtain the current fluctuation curves of the target core equipment after completing the target processing flow several times, interpret these current fluctuation curves in sequence, and determine whether these current fluctuation curves all have frequent current changes in the same period of time.

[0051] The situation where the current changes frequently refers to the situation where the number of changes in the current exceeds a preset threshold within a preset time period.

[0052] In the embodiment of the present invention, the target core equipment can be key equipment in the industrial field, such as an arc furnace in a steel plant, a reactor in a chemical plant, or a CNC machine tool in the manufacturing industry. These devices have extremely high requirements for power supply during operation, and the stability of the current directly affects production efficiency and product quality. The current fluctuation curve is collected in real time through the smart meter and sensor on the equipment, recording the current changes of the equipment in different process steps, and generating a fluctuation curve for analysis.

[0053] The preset threshold value not only defines the maximum allowable current change amplitude, but also specifies the maximum number of current changes within the preset time period. When the number of current fluctuations exceeds the preset threshold, it may cause unstable equipment operation, affect the continuity of the production process and product quality, and indicate that the current and voltage matching within the time period is unreasonable. This unreasonable current and voltage matching may cause the equipment to be inefficient or have a reduced quality in key process steps, and timely adjustments are required to ensure the stability of the production process.

[0054] Furthermore, the power marketing system based on the intelligent management platform also includes: The abnormal fluctuation period analysis module 200 is used to determine the abnormal fluctuation period of frequent current changes if it is determined that multiple current fluctuation curves have frequent current changes within the same period of time, and to judge whether the target core device has performed a specific process step consisting of multiple subdivided process actions within the abnormal fluctuation period.

[0055] Specifically, Figure 6 It shows a structural block diagram of the abnormal fluctuation period analysis module 200 in the system provided by an embodiment of the present invention.

[0056] Among them, in the preferred embodiment provided by the present invention, the abnormal fluctuation period analysis module 200 specifically includes: The abnormal fluctuation period determination unit 201 is used to determine that if it is determined that multiple current fluctuation curves have frequent current changes in the same period, the time period is an abnormal fluctuation period; The data search unit 202 is used to retrieve the process flow table of the target core equipment in the target processing process, and search the process flow table for the work content corresponding to the abnormal fluctuation period; The specific process step judgment unit 203 is used to analyze whether the work content corresponding to the abnormal fluctuation period contains a specific process step composed of multiple subdivided process actions, so as to confirm whether the target core equipment has performed the specific process step during the abnormal fluctuation period.

[0057] In an embodiment of the present invention, the interception of the abnormal fluctuation period is based on the analysis of multiple current fluctuation curves. When different current fluctuation curves show frequent changes in current within the same period, that is, when the number of changes in current within a preset time period exceeds a preset threshold, the time period is identified as an abnormal fluctuation period. Specifically, this period usually covers multiple adjacent time points, and the current fluctuation amplitude and frequency are large, indicating that there is a problem with the matching of power supply and equipment operation. The intercepted abnormal fluctuation period will be used to further analyze the operating status and process steps of the equipment.

[0058] The process flow chart is usually prepared by process engineers or production managers, recording the operation sequence of each step of the equipment when executing the target processing flow, the required time, the equipment parameters involved (such as current and voltage requirements), and the specific requirements of each process step. The basis for formulating the process flow chart includes the equipment operation manual, process specifications, production experience and historical data. The method of obtaining the process flow chart usually includes retrieving it from the company's production management system or MES (manufacturing execution system), or it can be obtained by directly communicating with the equipment operator or process engineer.

[0059] Specific process steps refer to key steps in the target processing flow that are composed of multiple subdivided process actions. These steps usually have a significant impact on product quality and production efficiency, and may involve complex operations. For example, in steel production, specific process steps may include a combination of heating, rolling, and cooling; in chemical production, it may involve the coordination of multiple reactions and separation steps; in CNC machine tool operations in the manufacturing industry, specific process steps may contain cycles of precision machining, measurement, and adjustment. Analyzing these steps can help determine the operating status of equipment during periods of abnormal fluctuations, thereby optimizing power supply and process flow.

[0060] Furthermore, the power marketing system based on the intelligent management platform also includes: The voltage variation amplitude determination module 300 is used to match the corresponding subdivided process actions for the fluctuation points of the current fluctuation curve in the abnormal fluctuation period if it is determined that the target core device has performed a specific process step within the abnormal fluctuation period, and obtain the voltage variation amplitude of the target core device when the subdivided process action matched by each fluctuation point is in progress.

[0061] Specifically, Figure 7 The structure block diagram of the voltage variation amplitude determination module 300 in the system provided by the embodiment of the present invention is shown.

[0062] Among them, in the preferred implementation manner provided by the present invention, the voltage variation amplitude determination module 300 specifically includes: The fluctuation point time determination unit 301 is used to determine the specific occurrence time of each fluctuation point of the current fluctuation curve in the abnormal fluctuation period if it is determined that the target core device has performed a specific process step in the abnormal fluctuation period; The subdivided process action matching unit 302 is used to match the actual execution time of each subdivided process action in the specific process step with the specific occurrence time of the fluctuation point in the abnormal fluctuation period, so as to identify the subdivided process action corresponding to each fluctuation point; The voltage variation amplitude determination unit 303 is used to obtain the voltage variation amplitude of the target core device when the subdivided process action matched by each fluctuation point is performed.

[0063] In the embodiment of the present invention, the specific occurrence time of each fluctuation point in the abnormal fluctuation period is determined by analyzing the current fluctuation curve. These moments mark the moments when the current fluctuates significantly during the operation process. For example, assuming that in a certain production process, the current fluctuates significantly at 5 seconds, 10 seconds and 15 seconds, these time points will be recorded as the specific occurrence time of the fluctuation point.

[0064] The actual execution time of each subdivided process action in a specific process step is matched with the previously determined fluctuation point occurrence time. Assuming that a subdivided process action is performed between the 6th and 8th seconds, if the fluctuation point occurs at the 7th second, this fluctuation point is matched with the subdivided process action, thereby identifying which process action is related to the current fluctuation.

[0065] Once the fluctuation points are matched with the corresponding subdivided process actions, the voltage change amplitude during these process actions can be obtained. The voltage change amplitude can be monitored in real time by sensors on the equipment, recording the difference between the voltage level during the process action and the normal level. For example, if the voltage drops from the standard 220V to 210V during the execution of a process action, the voltage change amplitude is 10V.

[0066] Furthermore, the power marketing system based on the intelligent management platform also includes: The power optimization strategy production module 400 is used to determine the current change amplitude of each fluctuation point according to the local curve of the current fluctuation curve of the target core equipment during the abnormal fluctuation period, and to provide a power optimization strategy for each fluctuation point according to the current change amplitude and voltage change amplitude corresponding to each fluctuation point.

[0067] Specifically, Figure 8 It shows a structural block diagram of the power optimization strategy production module 400 in the system provided by the embodiment of the present invention.

[0068] Among them, in the preferred embodiment provided by the present invention, the power optimization strategy production module 400 specifically includes: The voltage variation amplitude determination unit 401 is used to check, for each fluctuation point, whether the voltage variation amplitude of the target core device exceeds a preset amplitude when the subdivided process action matched thereto is performed; The voltage supply optimization unit 402 is used to optimize the voltage supply of the target core device when performing the subdivided process action matching a certain fluctuation point, if the voltage change amplitude of the target core device when performing the subdivided process action matching a certain fluctuation point is greater than a preset amplitude; The current supply optimization unit 403 is used to determine the current change amplitude of a fluctuation point according to the local curve of the current fluctuation curve of the target core device during the abnormal fluctuation period if the voltage change amplitude of the target core device during the subdivided process action matching a fluctuation point is not greater than a preset amplitude, and optimize the current supply of the target core device during the subdivided process action matching the fluctuation point according to the current change amplitude corresponding to the fluctuation point.

[0069] The preset amplitude is set based on the electrical characteristics and process requirements of the target core equipment, combined with historical operating data and the technical specifications of the equipment manufacturer. Specifically, the voltage and current requirements of the target core equipment in different process steps are taken into consideration, and the impact of voltage fluctuations in historical data on the performance and product quality of the target core equipment is analyzed. At the same time, the electrical tolerance range provided by the equipment manufacturer is referenced. After comprehensive evaluation, a voltage change amplitude that can ensure the stable operation of the target core equipment and does not affect the process quality is determined as the preset amplitude.

[0070] In an embodiment of the present invention, an example is given: it is assumed that a high-precision etching equipment (target core equipment) is managed in a semiconductor manufacturing plant. During operation, a certain subdivided process action of the equipment is a precision etching stage, which requires a very stable voltage, and the preset voltage change amplitude is ±5V. In step S401, it is analyzed that at a certain fluctuation point in the precision etching period, the voltage dropped from 220V to 213V, with a change amplitude of 7V, exceeding the preset ±5V threshold. In order to optimize the voltage supply, the voltage can be adjusted back to 220V by increasing the output of the voltage regulator during this fluctuation point, ensuring that the equipment maintains voltage stability in this critical process step, reducing the impact of voltage fluctuations on etching accuracy, and thus avoiding product quality problems.

[0071] If in another subdivided process action of the same device, such as the heating stage, the voltage variation is only 3V (between 220V and 217V), which does not exceed the preset ±5V threshold, then there is no need to optimize the voltage. Then according to step S403, further analysis found that the current fluctuation in this process step is large, and the variation reaches ±15A. In order to optimize the current supply, the current controller can be adjusted during this fluctuation point to stabilize the current supply within the range required by the device (for example, from the fluctuating ±15A to ±5A), ensuring that the heating process is stable, thereby avoiding the problem of uneven heating caused by excessive current fluctuations.

[0072] Prioritizing voltage optimization can enhance the overall stability of the system compared to directly optimizing current supply. Voltage, as a basic parameter of the power system, is crucial to the stability of the entire network. By prioritizing voltage adjustment and stabilization, system-wide instability can be effectively reduced, equipment failures or performance degradation caused by voltage fluctuations can be avoided, and the reliable operation of the entire power system can be ensured.

[0073] In addition, voltage optimization can better protect equipment and improve energy efficiency. Voltage fluctuations will impose additional electrical stress on the internal components of the equipment, which may cause component damage and shorten the service life. Maintaining voltage stability can extend the service life of the equipment and reduce maintenance costs. At the same time, by reducing unnecessary voltage fluctuations, it can improve the efficiency of power utilization, ensure that the equipment operates at the optimal energy efficiency point, and reduce energy waste.

[0074] The entry point of this technical solution in practical application can be in high-precision manufacturing or industries that require a highly stable power supply. For example, in semiconductor manufacturing, precision machining, or chemical reaction control, the equipment has very high requirements for voltage stability. By prioritizing voltage optimization, it can ensure that these high-demand processes operate in a stable power environment, reducing process quality problems and equipment damage caused by voltage fluctuations. In addition, for key equipment in large industrial parks, by prioritizing voltage optimization, the stability and reliability of the overall power system can also be improved, thereby reducing large-scale power failures.

[0075] For fields with complex and precise process steps, such as semiconductor manufacturing, precision machining or chemical reaction control, the strategy of prioritizing voltage optimization and combining current supply adjustment is particularly critical. The equipment in these fields has extremely high requirements for the stability and accuracy of power supply. Any slight fluctuation in voltage or current may have a significant impact on the process results. Through this refined power management solution, power companies can ensure that equipment has stable power support in each key step to avoid production defects or quality problems caused by power fluctuations.

[0076] This method can not only ensure the continuity and reliability of complex processes, but also significantly reduce equipment failure rate and maintenance costs, extend equipment life, and thus improve overall production efficiency. For industries that require highly precise operations, this is an important means to ensure product quality, improve customer satisfaction, and maintain competitive advantage.
