摘要
针对气体绝缘金属封闭电器(GIS)中由于隔离开关操作引起的快速暂态过电压(VFTO)的特性以及危害,以某500kV GIS变电站为例,利用电磁暂态仿真软件EMTP-ATP建立计算模型,计算分析了多种运行方式下隔离开关操作引起的VFTO,为合理制定操作方式提供工程参考。
This paper analyzes the features and hazards of very fast transient overvoltage( VFTO) caused by disconnecting switch operation in GIS. Then based on a 500kV GIS substation,it established a calculation model by using electro-magnetic transient simulation software ATP-EMTP,and thereby calculated and researched the VFTO caused by disconnecting switch operation in different modes,which provides reference to reliable operation mode decision in engineering.
