摘要

本文对阳城———江苏 5 0 0kV输电系统的工频过电压、潜供电流以及三相合闸、单相重合闸过电压利用EMTP进行了计算。分析表明

该系统工频过电压符合有关规定 ;潜供电流小于 10A

能保证单相重合闸成功 ;线路采用合闸电阻与MOA双重保护

可有效地限制合闸过电压。

Abstract

The computation of power frequency overvoltage

secondary arc current

3 phase closing overvoltage and single phase reclosing overvoltage in Yangcheng Jiangsu 500 kV power transmission system by EMTP is presented in this paper.The results show that the power frequency overvoltage is within the extent of design criteria

secondary arc current smaller than 10 A enables single phase reclosing to be successful

both colsing resistors and MOA can be used in the line protection to limit the closing overvoltage effectively.
