电力系统的继电保护装置状态检修综述

Review on Condition-based Maintenance of Relay Protection Device in Power System

继电保护装置在电力系统中具有重要作用,因此提高继电保护装置的性能受到学者的广泛关注。文中主要介绍了继电保护装置的校验周期与内容,以及如何对其进行维护;并探讨了变电站二次设备的状态监测及可能出现的问题。状态检修的主要作用,一是节能降耗,二是降低维修成本。

Relay protection device is very important in power system.Therefore,improving the performance of it is attracting more and more scholars＇ attention.This article mainly introduces the routine test interval and test contents of the relay protection devices,and illustrates how to maintain these devices.The condition-based monitoring of secondary equipment in substation and possible problems are then discussed.The two primary effects of condition-based maintenance are energy conservation and maintenance cost reduction.
