摘要
通过对一次相邻线路发生接地故障时,由于零序互感影响造成线路纵联零序方向保护误动的事故分析,说明了零序互感对零序方向元件的影响,并提出改进措施,对提高继电保护人员的故障分析能力有一定的借鉴意义。
The maloperation of pilot protection caused by zero-sequence mutual inductance when earth fault occurring in parallel lines is analyzed. Through the accident, the paper presents that zero-sequence mutual inductance will influence directional components. And the relevant countermeasures are put forward to enhance the fault diagnosing ability of relay protection engineers.
