【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。更多还原

【Abstract】 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 & 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.更多还原
