摘　　要：针对新疆电网220 kV线路的小电源、长距离特点,讨论了空载线路在长线路电容效应下产生的工频过电压。同时,应用PSCAD/EMTDC软件进行仿真,验证了理论分析的正确性,为新疆电网220 kV长线路的运行提供了一定的参考。According to the features of small power sources and long distance of 220 kV lines in Xinjiang Power Grid, the power frequency over-voltage generated on the unloaded lines due to the capacity effect was studied. The theoretical results were then validated by PSCAD/EMTDC simulation.

关 键 词：空载线路 电容效应 工频过电压 分布参数
