摘　　要：本文建立750kV双端电源供电超高压输电线路模型,分析安装快速接地开关和并联电抗器后熄灭潜供电流的效果,得出并联电抗器中性点接小电抗的方法对降低潜供电流和恢复电压的效果更好。本文重点研究模型中加入串补模块,验证旁路断路器及时合闸有利于潜供电流的熄灭。This paper establishes the 750kV double end power supply for ultra high voltage transmission line model, analysis of installation of grounding switch and parallel reactor extinguishes the arc current effect, that shunt reactor neutral small reactance method to reduce the secondary arc current and recovery voltage effect is better.This paper focuses on the study of models with series compensation module, authentication bypass circuit breaker closing time is beneficial to arc current.
