摘　　要：为进一步探究换流站直流侧短路故障,以某换流站为例,基于PSCAD/EMTDC平台开展仿真分析,以初步明确典型工况下的电压和电流暂态过程,以及过压和过流产生原因,在此基础上探讨了调整平波电抗器和线路避雷器参数的作用,以供参考。To further investigate details of short-circuit faults on DC side of converter stations,the present work conducted a case study on an actual converter station with simulation analysis based on PSCAD/EMTDC platform.Transient processes of voltage and current under typical operating conditions,and the causes of overvoltage and overcurrent were preliminarily determined.Based on this,the effectiveness of adjusting parameters of smoothing reactor and line surge arrester were discussed.
