Investigation of PLC for logic Selectivity Communication in Protection Systems

Salah Boughezala mohammed

Abstract

This paper reports an investigation of power line communication technique PLC for logic selectivity in protection systems. A simulation of power grid with two protection systems using PLC as communication process is performed by Simulink/Matlab program. Also, the attenuation characteristic of high frequency PLC signal is studied regards to resistance, inductance and frequency variation.
