摘　　要：输电线路工频参数因邻近线路的架设等因素而发生变化。测量邻近双回输电线路的工频参数时,在一回正常运行,另一回测量的情况下,测量将会受到邻近运行线路的严重干扰,仿真分析了220、110kV同杆架设线路几种运行方式下的干扰情况。计算结果表明,当线路长度为100km时,三相末端开路时的感应电压>1kV。The transmission lines' frequency parameters may be disturbed by factors such as adjacent working lines. This paper analyses the emulation of the joint use 220 kV and 110 kV transmission lines under several operating modes, which have different voltage classes. The results show that the induced voltage in the measuring line, length of 110 km, is over 1 kV when three phases end is opening circuit.
