电力系统继电保护状态检修分析

Analysis on Condition Based Maintenance of Power System Relay Protection

近年来,社会各领域对电力能源的需求量呈现出逐年递增态势,电力系统发生故障的频率也呈陡然上升之势,而继电保护作为检测电力系统故障,提供精准故障预警信号的重要装置,在整个电力系统当中始终占据着主导位置。一旦继电保护装置出现故障,检修人员需要利用先进的状态监测与诊断技术,排除系统的故障隐患,以确保电力系统能够持续安全运行。随着检修技术水平的逐年提升,这种新型的状态检修方法也日渐纯熟,并逐步在电力系统继电保护故障排查与检修工作中得到广泛应用。本文将围绕状态检修的应用优势以及在断电保护状态监测与故障排除中的实际应用效果展开全面论述。

In recent years,the demand for power energy in various fields of society is increasing year by year,and the frequency of power system failure is also rising sharply.As an important device to detect power system failure and provide accurate fault warning signal,relay protection has always occupied a dominant position in the whole power system.Once the relay protection device fails,the maintenance personnel need to use the advanced condition monitoring and diagnosis technology to eliminate the hidden trouble of the system,so as to ensure the continuous and safe operation of the power system.With the improvement of maintenance technology level year by year,this new type of condition based maintenance method is becoming more and more sophisticated,and has been widely used in the power system relay protection troubleshooting and maintenance work.This paper will focus on the application advantages of condition based maintenance and the practical application effect in condition monitoring and troubleshooting of power-off protection.
