摘　　要：在建立的配电网模型上利用ATP-EMPT软件对分布式发电(DG)引入故障限流器对过电压的影响进行仿真,从DG接入配电网位置不同、容量变化、短路位置变化等三个方面对单相短路故障引起的过电压问题做了计算和分析。结果表明,3种工况对产生配电网过电压有着重大影响,且故障限流器所起到的限制过压作用非常明显,对靠近故障限流器保护的母线其限压作用良好。On the basis of establishing power distribution net model,ATP-EMPT software was used to simulate impacts of a fault current limiter introduced to distributed generation（DG） on overvoltage.From different DG positions connected into distribution net,capacity change and short-circuit position change etc three aspects,overvoltage problem caused by single phase short-circuit fault was calculated and analyzed.Results show that the three working conditions have great impacts on overvoltage generated in power distribution net,and the fault current limiter plays a very obvious role in limiting overvoltage.For busbar near the fault current limiter,its voltage limit function is very good.
