Simulation of narrowband power line communication using ATP-EMTP

The simulation of narrowband power line communication is carried out by use of the J. Marti line model in the ATP-EMTP simulation program. The modal attenuation constants for three distribution line structures are obtained and frequency domain simulations on a `typical' rural 11 kV network are carried out. It follows that the 11 kV network studied presents a channel to narrowband power line communication frequencies characterized by strong multipath propagation effects and input impedance that is highly variable with frequency.
