摘　　要：在单机容量800 kW及以下的低压小型水电站中,由于发电机本身的制造工艺,发电机中性点运行方式等原因,实际运行中,发电机中性点有时有很大的零序电流通过,它对电站的安全运行带来故障隐患,但只要针对电站的实际情况,采取一定的措施,就能有效降低发电机中性点的零序电流.There is a large sum of zero sequential current in the generator under 800 kW while running to the neutral point because of workmanship and running method, which always causes malfunction. The paper focuses on how to lower zero sequential current in generator neutral point efficiently.

关 键 词：发电机中性点 零序电流 零序阻抗 降低措施
