摘要
依据2015年9月特高压锦屏换流站因雷击造成双极闭锁故障的事故,结合极控故障录波及极保护动作情况,理论分析故障原因,提出在特高压换流站直流分压器二次放电间隙处串联压敏电阻的反措建议,有利于直流系统的可靠稳定运行。
According to bipolar block faults caused by lightning stroke happened in Jinping UHV converter station in September 2015 and combined with the fault wave recorder and the protective actions of pole control, the fault reasons are analyzed theoretically, and the suggestions for anti - accident measures are put forward, that is, the varistor is in series connection at secondary discharge gap of DC voltage divider in UHV converter station, which is good for the stable and reliable operation of DC system.
