Problems solved by technology

[0003] The monitoring information of the substation is connected to the integrated control system. On the one hand, the sub-station lacks efficient monitoring data preprocessing means, and invalid information and secondary information frequently occur, which leads to the lack of stable and reliable data basis for further analysis of the main station; on the other hand , the master station system lacks rapid identification and fusion methods for massive information, resulting in a huge monitoring workload and low work efficiency

Abstract

A displacement reason recognition method and apparatus for a switchgear in a power grid, and a storage medium. The method comprises: acquiring a device status of a switchgear in a power grid, an operation record of the switchgear and a displacement record of the switchgear, and according to the device state of the switchgear, the operation record of the switchgear, the displacement record of the switchgear and a time sequence relationship between records, performing correlation analysis to acquire an analysis result; and based on the analysis result and a pre-set displacement strategy, recognizing a displacement reason of the switchgear.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a method for identifying switch displacement causes of grid equipment states and event timing relationships. Background technique [0002] With the continuous deepening of the construction of the "big operation" system of the State Grid Corporation of China, the operation mode is shifting towards the integration, intensification, and leanness of dispatching, monitoring, and operation. . At the same time, with the rapid expansion of the grid scale and the rapid increase in the number of substations put into operation, the amount of monitoring information in the control automation system continues to rise, which puts forward higher requirements for the daily monitoring, abnormal analysis and accident handling of the power grid control personnel. [0003] The monitoring information of the substation is connected to the integrated control system. On the one hand, the sub-station...
