| 摘 要： | 通常10kV配电线路在不同的间距加装氧化锌避雷器(MOA)以限制配电网事故。为更有效地利用这一提高电网安全的技术,建立了Chowdhuri-Gross模型并运用ForTrain编程计算了差分方程以及在不同间距加装MOA的线路绝缘子闪络时的施感电压,再用施感电压与经验公式求出了安装MOA后线路的闪络次数。计算表明,较之没有安装MOA时线路每200m安装一组避雷器可降低感应雷事故81%。

| Abstract: | To constrain the fault of distribution line,Metal Oxide Surge Arrester(MOA)is installed on 10 kilovolt distribution line at every certain distance.To use this technology effectively,Chowdhuri-Gross model is installed to calculate the inducing over voltage by way of Fortrain.Then the authors use the result to calculate the decline of the probability of flashover on line and contrast with line without MOA.The computation results show that installing a set of arrester per 200 m can reduce 81% faults of indirec... |
