摘　　要：本文的主要目的是向大家提供一种分析、判断零序功率方向继电器接线正确与否的基本原理与方法。文中介绍了黄丹电厂对拒动的线路零序保护进行检查的过程,并采用电压、电流相位关系分析法,通过带负荷检测试验,最终判定电流回路极性接反。经修改电流回路极性后再次带负荷试验,零功方向继电器动作正确。The aim of this article is to offer you a kind of analysis, judgement zero sequence directional power relay wiring correctness of the basic principle and method. This paper introduces HuangDan power plant for refusing action of zero sequence pilot protection circuit inspection process, and USES the voltage, current phase relation analysis method, through carrying load test, final judgment current circuit at the polarity. The amended current circuit polarities with again after load test, zero reactive direction relay action correctly.
