摘　　要：某换流站小组交流滤波器开关在调试过程中发生分闸命令延迟半个周波,导致产生较大的零序电流。分析引发该现象的原因,并提出防控措施与解决办法。In the commissioning process of a converter station group's AC filter switch,the opening command was delayed by half a cycle,resulting in a large zero-sequence current.The cause of this phenomenon is analyzed,and the prevention and control measures and solutions are proposed.
