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.
