摘要

随着微机继电保护的广泛应用

继电保护装置和二次回路的电磁干扰问题越来越受到重视。本文以湖南某电厂500 kV升压站微机保护装置受电磁干扰影响而发生误动为案例进行分析

探讨了骚扰源的形成、特征及其传播到二次回路的途径。并结合现场实际提出有针对性的处理意见和防御电磁干扰的措施

以期对优化设计及现场安全运行提供参考。

Abstract

With the wide application of microcomputer relay protection

more and more attention has been paid to electromagnetic interference of relay protection device and secondary circuit.This paper takes the case of misoperation of microcomputer protection device of 500 kV booster station in a power plant in Hunan

which is affected by electromagnetic interference

and discusses the formation and characteristics of disturbance source and the route of its propagation to the secondary loop.In addition

the paper proposes specific treatment suggestions and measures to prevent electromagnetic interference based on the actual situation.It is expected to provide reference for optimization design and safe operation on site.
