Signal Propagation Modeling in Power-Line Communication Networks
In this paper, we present a propagation model for the power-line communication (PLC) networks, ased on the frequency-domain analysis. First, we let a simple two-port model of the network. Then, we calculate a complex attenuation factor from -parameters, expressed in terms of impedances, easily calculable/measurable from the network ports. We explain simultaneously calculation and measurement methods based on the same principle, and then compare the results with direct measurements performed in the network designed for this purpose. We provide all of the elements for a simple end efficient propagation model. They include propagation by crosstalk between different circuits in, for example, three-phase networks, as well as the influence of the loads connected to the ports of different circuits in such networks. We have concluded that the model is suitable for PLC channels simulations that give very accurate results and enable modeling of wide-band channel characteristics.
