摘　　要：在宁东～山东±660 kV直流输电示范工程银川东换流变电站330 kV交流场带电前,针对交流线路的充电功率是否导致工频过电压,以及交流滤波器和并联电容器在投切换入过程中是否产生操作过电压,进行了仿真计算。计算结果表明,各条线路均可作为该换流站的带电启动线路,且单独投入滤波器或电容器时产生的过电压不会对系统产生较大影响。Before electrifying 330 kV alternating current（AC） field of Yinchuan Eastern converter station of Ningdong to Shandong ±660 kV DC power transmission demonstration project,in order to know whether the charging power of AC transmission lines will lead to AC frequency overvoltage,and whether when switching the AC filter and shunt capacitor will produce operation overvoltage,makes the system simulation,the result shows every line can all be the electrifying startup line of this converter station,the overvoltage switching the AC filter and shunt capacitor will not bring big influence for the power system.
