摘要
通过理论分析,找出造成500 kV同塔双回线路工频过电压大小发生变化的影响因子。利用PSCAD电力仿真软件搭建电力仿真模型,对这些影响因子进行仿真校验,统计分析工频过电压变化的一般规律。
Through theoretical analysis, the influencing factors that cause the change of power frequency overvoltage of 500 kV double circuit lines on the same tower are found. The PSCAD power simulation software is used to build the power simulation model. The influence factors are simulated and verified, and the general law of power frequency overvoltage variation is analyzed.
