Power line carrier technologies: a review

Abstract

This paper gives an elaborate insight into the Power Line Carrier (PLC) communication technology in the power system. It explores the various characteristics, properties, and advancement of the power line carrier system and individual analysis of its components. These components, however, are in concerning power line carrier communications over high voltage lines majorly used in transmission stations. Power Line Carrier (PLC) components, including wave traps, coupling capacitors, line matching units, were highlighted. The paper discussed the operation principle of the Power Line Carrier (PLC) system together with their functionalities and how it makes transmission of information and power possible. It gives us the step by step functionalities of the different parts and how they make the information dispersion possible. A communication strategy was deployed for the effective transmission of data and information over the power line channel. Challenges were considered, solutions, and future directions for the advancements in the power line carrier system were also provided.
