摘要

介绍了一起110kV线路发生转换性复杂故障造成主变压器和反方向110kV线路越级跳闸的事件。通过对故障波形和故障电压、电流向量关系的仿真分析，验证了保护动作的行为，分析了事故发生的原因，为今后分析类似故障提供了参考。

Abstract

An override trip accident caused by a 110 kV line fault is described.Through analysis of the fault waveform and vector relations of fault current and fault voltage，the correctness of the protection actions is verified.The analysis can be used as a reference for similar future faults.Finally，the corresponding rectification measures are put forward in order to avoid similar override trip accidents.
