Analysis on Condition Based Maintenance of Power System Relay Protection

Zhou Zhong-xia

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

狀态检修是计算机技术、移动通信技术、互联网技术基础上衍生出的一种新型的故障检修方式，这种技术主要借助干于监测设备的数据采集功能，收集电力系统的继电保护装置在运行过程中产生的各种数据信息，并对数据进行严格筛选和精准分析，以确定故障类型与故障部位，进而制定针对性的检修方案，确保继电保护装置能够始终处于正常运转状态。

1 状态检修的应用优势分析

电力系统的安全稳定运行与人们的日常生活有着密切关联，一旦电力系统出现故障，局部区域将中断供电，进而严重影响居民的正常生活。为了提高供电稳定性与可靠性，一种新型的状态检修方式应运而生。与传统的检修方式相比，状态检修更加注重事前预防与过程检修，这不仅降低了设备检修成本，同时，也提高了检修效率。目前，电力系统当中的继电保护装置的故障率显著降低，土要是因为，电力系统在出现运行故障后，在离故障部位最近的设备会立即断开连接。这种保护措施能够缩小停电范围，使其他没有运行故障的区域保持正常的运行状态。另外，如果系统出现故障，继电保护装置可以在最短的时间内完成断路动作，有效降低故障元件的功能损耗，并快速查找出故障部位。因此，电力系统继电保护的状态检修应用优势可以总结为以下几方而内容。
