摘　　要：磁控式并联电抗器(MCSR)作为电网中十分重要的无功补偿设备,具有平滑调节容量,消除操作过电压和潜供电流的作用。文中利用Ansoft Maxwell软件搭建了二维有限元模型,并使用外电路编辑器作为有限元激励源,通过仿真网侧绕组接地故障、网侧绕组匝间故障、控制绕组接地故障、控制绕组匝间故障,分析了在这4种不同故障情况下磁控式并联电抗器的工作特性。The magnetically controlled shunt reactor(MCSR)is a very important reactive power compensation equipment for power grid,which has the function of smooth regulating capacity,eliminating the overvoltage of operation and submersible current.The structure of MCSR is complex,and it works in the saturation state of AC and DC mixing.Its precise mathematical model construction and internal fault analysis are more complex,and there are few references at home and abroad.This paper uses Ansoft Maxwell software to build two-dimensional finite element model of MCSR,and the external circuit editor as the excitation source of the finite element model.Through simulation line winding earth fault,line winding turn-to-turn fault,control winding earth fault,control winding turn-to-turn fault,analyzed the four kinds of fault cases,the working characteristic of MCSR.
