Error prevention system and method for secondary system anomaly recognition of substation under multiple associated scenes

Abstract

The invention belongs to the fields of power secondary system abnormal state recognition and misoperation prevention and particularly relates to an error prevention system and method for secondary system anomaly recognition of a substation under multiple associated scenes. According to the method, based on normalization of substation information description and normalization of an operation process, an integrated error-prevention function and an error prevention strategy are deployed and configured in devices at all levels of a secondary system comprising devices, a station server and a scheduling server, and information modeling and recognition are performed on the running states of the secondary devices and the secondary system in the substation; and meanwhile, before primary operation and secondary operation on the substation, whether the operation can cause a system anomaly or misoperation is judged through rehearsal according to a power grid topological structure and the running setting state of the secondary devices, and if the system anomaly or the misoperation is caused, warning or forbidding or prompting is actively sent out through analysis, error prevention and remedy are performed on the misoperation or the abnormal running state occurring in the system, and therefore forward intervention on field operation and maintenance work is realized.

Description

technical field [0001] The invention belongs to the field of abnormal state identification and misoperation prevention in electric power secondary systems, and particularly relates to a method of identifying abnormal state and misoperation of substations through standardized model information description in multi-association scenarios of substations, and avoiding malignant accidents based on the execution of anti-misoperation strategies Anti-mistake system and method. Background technique [0002] The operation reliability of the power system is the basis and one of the most important technical indicators for the realization of power production and operation functions. Misoperation in the substation and abnormal operation of the system may lead to serious accidents, resulting in losses of personnel, power grids, and equipment. At present, there is an anti-misoperation locking system for primary equipment in substations, also known as "five preventions", which has been widely...

AI Technical Summary

Problems solved by technology

In the process of on-site operation, maintenance and maintenance, relay protection misoperation events caused by secondary equipment such as merging units have occurred many times. There is currently a lack of unified and standardized opinions and solutions for the anti-misoperation technology of the secondary system.
