摘要
以两起110kV线路零序方向保护反方向误动为例,通过对现场二次接线及自身装置检查,并基于保护装置的程序逻辑、依据故障录波采样报告,分析了零序保护误动原因,指出执行继电保护反事故措施的重要性。
Taking two 1 lOkV lines zero-sequence directional protection in reverse malfunction for an example, accord- ing to on-site secondary wiring and checking device, the cause of zero-sequence protection malfunction is analyzed in terms of program logic of protection device and reports of failure recorders. And it points out the importance of implementation of relay ]protection anti accident measures.
