摘要
基于电力系统电磁暂态仿真软件PSCAD对电力系统中三种最主要的引起电压暂降的原因:短路故障,感应电机启动和变压器投运进行了电磁暂态仿真。根据仿真结果对不同暂降源引起的电压暂降时的电压变化情况进行了分析,并总结了短路故障,感应电机启动和变压器投运时引起电压暂降的特点。为今后根据监测波形进行电压暂降源的辨识提供依据。
Simulation is carried out based on simulation software PSCAD of electromagnetic transient in the power system on the power system voltage sags caused by three major reasons： short-circuit fault, induction motor starting and transformer running. The simulation results of different dips caused by different sources are analyzed and summarized, which provide a basis for source identification of the voltage sags.
