摘要
介绍220kV主变中性点运行方式与零序保护、间隙保护的关系,并从110kV系统发生接地故障的角度进行分析,提出220kV变电站主变中性点运行方式的优选方法。
The relations among operation mode and zero sequence protection and gap protection are introduced. The grounding fault of 110kV system is analyzed and the optimal selection of operation mode of neutral point in 220kV substation is proposed.
