摘　　要：为解决电力系统继电器保护二次回路故障监测反应速度慢、控制精度差的问题,本文开发了一种新的继电保护二次回路故障监测系统。该系统能建立多层次的分布式数据监测架构,实时采集电路系统故障信息,并利用动态频谱检测技术实时定位故障区域参数,实现对继电保护二次回路故障的动态监测和预警。实际应用表明,新的故障动态监测和预警系统能将故障监测反应时间缩短72.4%,将监测准确性提升至98.6%。In order to solve the problems of slow response speed and poor control accuracy power system relay protection secondary circuit fault monitoring,this paper developed a new relay protection secondary circuit fault monitoring system.This system can establish a multi-level distributed data monitoring architecture,achieve real-time collection of circuit system fault information,and use dynamic spectrum detection technology to locate fault area parameters in real-time,achieving dynamic monitoring and early warning of relay protection secondary circuit faults.Practical applications,the new fault dynamic monitoring and early warning system can reduce fault monitoring response time by 72.4%and improve monitoring accuracy to 98.6%.
