Abstract

This invention discloses an orderly control method for a group of high-power electrical equipment. The method includes the following steps: Step 1: Integrating a time-limited self-optimizing orderly control strategy and a load-limited self-optimizing orderly control strategy; Step 2: Setting a mandatory delay time limit, which is derived by considering the production task surplus; Step 3: The mandatory delay time limit is not set to a specific value; Step 4: The system performs a comprehensive judgment; Step 5: Executing the time-limited self-optimizing orderly control strategy; Step 6: The system prioritizes equipment with more production task surplus time for mandatory delay waiting; Step 7: If the peak shaving task still cannot be met, other equipment is selected to participate until the peak shaving task is satisfied. This invention, an orderly control method for a group of high-power electrical equipment, decomposes the production plan and implements differentiated control strategies, allowing the two conflicting aspects of ensuring power grid stability and ensuring production to be managed in a unified manner to a certain extent, further improving the peak shaving capability of the orderly management system.

Description

Technical Field

[0001] This invention relates to an orderly control method for a group of electrical equipment, and particularly to an orderly control method for a group of high-power electrical equipment, belonging to the field of electrical equipment control technology. Background Technology

[0002] The core algorithm of a production sequence control system for power equipment groups uses historical power load curves to predict future power load curves. Sudden changes in products and adjustments to processes can introduce errors in load forecasting for subsequent adjacent cycles. The overlap rate between the historical load curves used in the forecast and the actual future load curves will affect the accuracy of load control. This paper's solution adds a production planning management + product AI self-learning algorithm model to the original load forecasting, aiming to reduce peak grid load by improving the accuracy and speed of load forecasting. The so-called product AI self-learning algorithm refers to monitoring the characteristics of power consumption curves of production equipment, continuously learning and accumulating the characteristic curves of various product electrical parameters (including current curves, power factor curves, active / reactive power curves, etc.), summarizing and classifying them to establish a product characteristic catalog database (also called a process electrical parameter model library). When performing load forecasting, it can quickly identify the product category, the number of electrical parameter curves, and other indicators, which can significantly improve the accuracy and response speed of load forecasting.

[0003] The original power equipment group production sequence control system provided two control strategy algorithms: a time-limited self-optimizing ordered control strategy and a load-limited self-optimizing ordered control strategy. The time-limited self-optimizing ordered control strategy aims to implement orderly management within a predetermined time limit while minimizing production disruption. Due to the short time limit, the equipment commissioning time may not necessarily be the optimal load point, but power load parameters are compromised to ensure production planning. The load-limited self-optimizing ordered control strategy aims to achieve orderly control of equipment operation while ensuring grid stability. This strategy breaks the time delay limit of equipment operation, interfering with the production process to some extent, to achieve target control of power load. Summary of the Invention

[0004] The purpose of this invention is to provide an orderly control method for a group of high-power electrical equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for orderly control of a group of high-power electrical equipment, wherein the steps of the method are as follows:

[0006] Step 1: Integrate the time-limited self-optimizing ordered control strategy and the load-limited self-optimizing ordered control strategy;

[0007] Step 2: Combine the production plan, analyze the production tasks and spare time of each piece of equipment, and combine the production task saturation to set a mandatory delay time limit based on the original delay waiting time limit. The mandatory delay time limit is derived by following the production task spare time.

[0008] Step 3: The forced delay time limit is not set with a specific value. The total forced delay of a single device should be less than the surplus time of the production task.

[0009] Step 4: The system makes a comprehensive judgment;

[0010] Step 5: If the system's peak shaving task can be completed within the normal delay waiting time limit, then execute the time-limited self-optimizing ordered control strategy;

[0011] Step Six: When the system's peak shaving tasks cannot be met within the normal delay waiting time limit, the system prioritizes selecting equipment with more spare time for production tasks to force a delay waiting time;

[0012] Step 7: If a device still cannot meet the peak shaving task after entering the forced delay strategy, then select another device with the second-highest spare time of the production task to participate, and so on, until the peak shaving task is met.

[0013] As a preferred embodiment of the present invention, in step two, the set mandatory delay time limit is determined by ensuring the peak load of the power grid.

[0014] As a preferred technical solution of the present invention, in step three, the forced delay time limit is adjusted at any time according to the follow-up production plan tasks.

[0015] As a preferred technical solution of the present invention, in step four, the judgment is made based on the two conditions of combining the production plan and the peak shaving task.

[0016] In a preferred embodiment of the present invention, in step six, the server's processing resources are constant system peak-shaving tasks.

[0017] The beneficial effects of this invention are as follows: This invention provides an orderly control method for a group of high-power electrical equipment. Compared with existing technologies that decompose production plans to achieve differentiated control strategies and prioritize control levels, this invention integrates the two contradictory aspects of ensuring power grid stability and ensuring production to a certain extent, further enhancing the peak shaving capability of the orderly management system and improving the rational applicability of peak shaving strategies.

[0021] Step 2: Combine the production plan, analyze the production tasks and spare time of each piece of equipment, and combine the production task saturation to set a mandatory delay time limit based on the original delay waiting time limit. The mandatory delay time limit is derived by following the production task spare time.

[0025] Step Six: When the system's peak shaving tasks cannot be met within the normal delay waiting time limit, the system prioritizes selecting equipment with more spare time for production tasks to force a delay waiting time;

[0026] Step 7: If a device still cannot meet the peak shaving task after entering the forced delay strategy, then select another device with the second-highest spare time of the production task to participate, and so on, until the peak shaving task is met.

[0027] Preferably, in step two, the set mandatory delay time limit is determined by ensuring the peak load of the power grid.
