Analysis and Modeling of Brazilian Indoor PLC Channels Controlled Environment - Testing and Validation

摘要

This work is a revision, application and comparison of the main models found in the literature for the transfer and noise functions in the channel for communications in power transmission lines (PLC ??? power line communication). Considering the characteristics of brazilian residential electrical installations, comparisons of measurements with models for the transfer function, the ABCD transmission matrix model as the most efficient and flexible in the increase of the channel sections and branches. The series resonant circuit model may be very precise and allows the implementation of an analog channel emulator using discrete components. However the classical model with eco demonstrated a better theoretical basis for transmission lines. The six different types of noise present on the power grid were measured and modeled. A very realistic model is simulated using Markov chains for modeling the non-periodic impulsive and burst noise.
