摘要

针对一起某110 kV线路雷击跳闸后，由于电动机返送电导致线路重合失败的复杂电网事故，从现场录波记录、事故现象、保护行为、断路器动作时序等方面进行详细分析，深入探讨了电动机返送电对110 kV终端系统的影响，并提出了合理的应对措施和改进方法。

Abstract

Aiming at a complex power grid accident that the reclosing fails due to the power return from motor after a lightning trip-out of 110 kV transmission lines

the impact of power return from motor on 110 kV terminal system is analyzed in detail in the aspect of wave recording

accident appearance

relay protection behaviour and time sequence of breaker action. The reasonable countermeasures and improvement methods are also proposed.
