| 摘 要： | 建立了一个110kV长线供电系统模型,用软件EMTP对该系统进行了工频过电压和操作过电压的计算。结果表明:如线路长度在200km左右,系统的工频过电压和操作过电压均在允许范围之内,除在线路上加装一定容量的并联电抗器外,不需要采取特别的措施加以限制。

| Abstract: | The computation of power frequen cy overvoltage and switching overvoltage in a model of110kV transmission network w ith a long line by software EMTP is presented in this paper.The results show tha t the power frequency overvoltage and switching overvoltage are all within the limita-tion of design criteria if the line is around200km,so it needs no speci al means to limit these overvoltages except some shunt reactors added on the lin e. |
