| 摘 要： | 随着大量分布式电源(DG)接入配电网,电压暂降现象将变得更为复杂。基于某地区电网实际网络构架,利用EMTDC/PSCAD建立了含分布式电源的配电网电压暂降分析模型,进行了典型算例仿真研究。仿真结果表明:逆变器型DG的接入能够在一定程度上抑制配电网电压暂降幅度和持续时间;同时,DG的控制策略、接入位置和出力都会对电压暂降产生一定的影响。

| Abstract: | With large numbers of distributed generations (DGs) installed in the distribution network, the problem of voltage sag becomes more complicated. Based on the realistic power grid frame of a network, and setting up an analysis model of its voltage sag with EMTDC/PSCAD, this paper makes simulation research on the typical cases. The results show that the inverter-based DG interconnected into the distribution network can mitigate the voltage sag to some extent while its control strategy, installed position and output power exert certain influences on the voltage sag. |
