摘要
针对河北省南部电网近期投运的辛集-沧西500 kV输电线路进行系统过电压计算,对该线路不完全换位,且带有高压并联电抗器的情况,应用EMTP程序进行了线路参数以及线路的非全相工频谐振过电压的计算和分析,提出了必要的限制措施。
Calculating of the system overvoltage for the Xinji-Cangxi 500 kV transmission line which is put into operation recently is made.That transmission line is incomplete displacement with HV shunt reactor.The overvoltages of resonance in non-full phase operation for that transmission line are calculated and studied using the EMTP program.
