微机保护不对应启动重合闸保护动作分析

Analysis on Protection Action of Microcomputer Protection Reclosing Device Based on Breaker Uncorresponding Position

针对不对应启动重合闸保护动作模拟试验中两套配置的微机保护装置动作行为不一致现象,结合各种常用微机保护装置的动作时间分析,认为两套保护重合闸命令发出存在时间差是导致保护装置动作行为不一致现象发生的原因,并提出运行中的注意事项。

In simulation two protection devices have different actions during protection action simulation test, this paper analyzes the time of usual protection devices action,and considers that the reclosing devices different actions lead to protection devices different actions,and puts forward attentions during operation.
