摘　　要：对超高压线路操作过电压进行了理论分析,并应用PSCAD/EMTDC软件进行了仿真.仿真计算验证了理论分析的正确性,同时表明,跳闸过电压主要与跳闸时刻流过断路器的线路电流和电源摆开角有关,合闸过电压与合闸前的残余电压有关.The operation overvoltage of extrahigh voltage line is analyzed theoretically. The results are validated by PSCAD/EMTDC simulation, and the simulation results also show that the trip overvohage is mainly related to the line current and the power establishing width angle when tripping occurs. It is also shown that the switch on overvoltage is mainly related to the residual voltage before switching.
