摘要：
In order to simulate the channel characteristics of actual low voltage power cable in laboratory environment, the lumped parameter cable model should be established under the power line communication band. A method is proposed to obtain the resistance and inductance by electromagnetic simulation and capacitance combined with the method of measuring and calculating distributed capacitances in open circuit tests. And on this basis, the transmission parameters of the cable are obtained. The transmission parameters are converted to Y parameters, and the π-type equivalent circuit is established. Based on the vector matching method, the passive equivalent circuits of each branch of the π-type equivalent circuit are solved, and the lumped parameter cable model is established. By comparing the calculation results of transmission and impedance characteristics with the distributed and lumped parameter models, the accuracy of lumped model is proved. The model can simulate actual cables of various lengths by circuit cascades. © 2019 Automation of Electric Power Systems Press.
