中文摘要: 讨论了空载线路在电容效应下产生的工频过电压,并对并联电抗器抑制工频过电压的作用进行了理论分析.同时,应用PSCAD/EMTDC软件进行仿真,仿真计算验证了理论分析的正确性,表明并联电抗器装设在线路末端时抑制工频过电压的效果最好,且与线路补偿度有关.
Abstract:The power frequency overvoltage of unloaded line because of the capacity effect is studied,and the effect of eliminating power frequency overvoltage using shunt reactors is analyzed.The theoretical results are validated by PSCAD/EMTDC simulation,and the simulation results also show that when shunt reactor is installed at the receiving end of transmission line the effect of restraining overvoltage is strongest and is related to the degree of compensation.
