摘要

利用EMTP对公伯峡330kV输电系统的工频过电压及操作过电压进行了计算。结果表明

该系统的工频过电压符合有关规定。取消线路开关的合闸电阻

而仅用金属氧化物避雷器

即可有效地限制操作过电压。

Abstract

The computation of power frequency overvoltage and switching overvoltage in a330kV power transmission project of Gongbo Gorge by EMTP is presented in this paper.The results show that the power frequency overvoltage is within the extent of design criteria

and the closing resistor inside circuit breaker can be eliminated while the switching overvoltage can be limited effectively merely by MOA.
