220kV变电站继电保护改造中存在的问题及解决措施

Problems and Solutions in Relay Protection Reform of 220 kV Substation

电网系统中,220kV变电站是核心组成,为变电所变电运行提供了必要支撑,也使电网系统基础运行更加完善,用电用户可获取高品质电能服务。一般220kV变电站的运行环境相对复杂,所以要借助继电保护方法对运行故障予以及时处理。基于此,将220kV变电站继电保护改造作为主要研究内容,重点阐述其中存在的问题,并提出相应的解决措施。

In the power system,220 kV substation is the core component,which provides the necessary support for the operation of the substation,makes the basic operation of the power system more perfect,and enables users to obtain highquality power services.Generally speaking,the operation environment of 220 kV substation is relatively complex,so it is necessary to use relay protection method to deal with the operation failure in time so as to avoid the occurrence of operation risk. Based on this,regards the relay protection transformation of 220 kV substation as the main research content,focuses on the existing problems,and puts forward corresponding solutions,hoping to be helpful.
