Patrol analysis method and device for centralized control center

Abstract

The invention relates to a patrol analysis method and device for a centralized control center. According to the method, after real-time load data in a power grid monitoring control system is acquired, the real-time load data is regularly stored in a physical database and simultaneously, real-time load data information is subjected to statistics computing processing to generate regional load data; then data in the physical database is subjected to load prediction based on a load prediction algorithm to obtain predicted load data generated in a certain time in future, and the predicted load data is subjected to statistical calculation processing to obtain regional predicted load statistical data; and calculation and analysis of an equipment load rate are carried out according to the real-time load data, the regional load data, the predicted load data, the regional predicted load statistical data and equipment model parameter information of the power grid monitoring control system, equipment is judged whether reach the equipment patrol warning grade, and an equipment patrol list is automatically generated after the equipment patrol warning grade is reached. According to the method, the patrol list can be automatically generated and the equipment can be more accurately overhauled; and the safety performance and operating efficiency of a whole power grid can be improved.

Description

technical field [0001] The invention relates to the technical field of power grid operation safety, in particular to a maintenance inspection method and device for optimizing an accident handling process in a centralized control center. Background technique [0002] The centralized control center (referred to as the centralized control center), as the connection hub between the dispatching center and the substation, directly faces the operation and maintenance management of the power system and power equipment, and integrates command, dispatch, monitoring, and operation. It plays an important role in improving the self-healing ability of the power system and the reliability of power supply. [0003] Traditional accident handling process: When a fault occurs, the centralized control center will often receive hundreds of alarms from the substation within tens of seconds. Record disconnected circuit breakers and protection action information, and distribute them to various dep...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the problem that the existing centralized control center has relatively high requirements for monitoring personnel and can only manually fill in the basic situation of the inspection and maintenance list by the team operators of the substation after the accident occurs, and provides an optimized centralized control center. Control center inspection analysis method, with predictive intelligent auxiliary support function, can automatically generate inspection list and more accurately reach the maintenance equipment
