A Model for 10kV Overhead Power Line Communication Channel

Full text: PDF


In order to achieve reliable and high-speed 10kV power line carrier communications, it is necessary to study the characteristics of channel. Based on the multi-conductor transmission line theory, the chain matrix channel model is established. A lumped parameter model of distribution transformer is proposed from impedance measurement in the frequency range 50-500kHz. The terminal voltages and currents of whole network are derived, which reveals the causes of frequency selective fading. The simulation results are compared and analyzed between different signal frequencies and propagation paths, based on a simplified model of distribution network.
