| 摘 要： | 针对气体绝缘封闭式开关设备(GIS)中快速暂态过电压(VFTO)产生的原因、出现的种类、对GIS本身以及对外部设备的危害等问题,对某水电站500 kV GIS建立了系统的仿真模型,利用电磁暂态仿真软件ATP-EMTP,计算分析了隔离开关在3种典型操作方式时在主变压器线圈上引起的VFTO,并提出了防止VFTO的运行操作要求。

| Abstract: | According to cause, category, and damage of VFFO of 500 kV GIS, this paper established a simulation model of 500kV GIS. By using electro-magnetic transient simulation software ATP-EMTP, the paper calculated the VFFO on the main transformer coil caused by three kinds of disconnector operating mode and proposed operation requirements for preventing VFTO. |
