摘　　要：利用PSCAD仿真软件建立电力电缆局部放电传播的仿真模型,通过控制断路器的开断来控制脉冲信号的宽度,通过改变局放脉冲信号发生器与信号检测传感器之间的电缆长度来模拟局放信号在不同长度的电力电缆中的传输,然后对比分析检测到的电压波形的变化规律,为发展电力电缆局放信号的检测与定位技术提供参考。The simulation model of power cable partial discharge signal transmission was established by PSCAD simulation software.The pulse signal of power cable partial discharge was simulated by pulse signal.The transmission process of partial discharge signal in power cable was simulated by changing the length of cable between the location of partial discharge pulse signal and the positions of signal detection.It provides references for studying the detection technology of power cable partial discharge signal.
