摘要

根据某地区四个变电站的实际接线

利用EMTP对GIS投切 110kV空载变压器的快速暂态过电压进行计算

对幅值、频率作了分析

并与实测进行了比较。

Abstract

According to the practical circuit of four 110kV substations

a calculation of VFTO by EMTP is presented while 110kV GIS switches on and off no load transformer. Besides

VFTO’s amplitude and frequency are analyzed. A comparison between calculation and field measurement is also made.
