一起500kV线路测量电压空开偷跳导致有功功率异常分析

Analysis of Active Power Anomaly Caused by a Voltage Open Sneak Jump on a 500kV Line

对某变电站一条500kV线路由于线路CVT端子箱的监控测量空气开关偷跳引起的有功功率异常,且监控后台无告警报文、光字牌不亮的事件进行了分析,总结了经验教训,并提出了整改措施。

This paper analyzes a 500kV line in a substation,and analyzes the abnormal active power caused by the broken air switch of the CVT terminal box of the line,no warning message in the monitoring background and no bright light sign,and proposed corrective measures.
