摘要
变电站直流系统故障可能导致变电站处于失控状态,严重情况下可能导致全站失电。分析一起复杂的直流系统异极性环网多重报警事故,依靠拉路试验结果分析与判定直流故障类型并给出可行的解决方案,最后依据本次事故案例给出建议。
Substation DC system failure may cause the substation to be out of control.In severe cases,it may cause power loss in the whole station.A complex DC system with multiple polarity ring alarms was analyzed and the DC was analyzed and determined by means of pull test results.The type of failure and the feasible solution were given.Finally,the suggestions based on this accident case were given.
