Power line communication: A review on couplers and channel characterization

Abstract

<abstract> <p>Powerline communication is gaining momentum with the rise of the smart grid, the Internet of Things as part of the 4th industrial revolution and associated applications such as transportation and energy efficiency. Coupling and channel characterization are essential parts of a power-line communication system. Therefore, understanding these components allows performance evaluation and prediction of the system. This paper presents an entire review of couplers and channel characterization modeling techniques used in narrow and broadband power-line communication systems. Types and applications of different couplers are presented; a review of different power-line communication channel modeling techniques and the fundamentals allows a clear understanding of factors influencing or affecting the signal propagation through the channel. The purpose of this review is to guide researchers and system designers looking for literature resources on couplers and channel characterization for power-line communication applications.</p> </abstract>

Broadband Power Line Communication in Railway Traction Lines: A Survey

“…Note that the transmitted signals must be superimposed to the waveform of the power supply, whereas the received signals must be separated from the waveform of the power supply: couplers are adopted to this end. Couplers can be classified according to voltage level, DC or AC regime, frequency band, physical connection type (capacitive, inductive, or resistive), mode of propagation (common or differential), or number of connections (single-input-single-output, single-input-multi-output, or or multi-input-multi-output) [45]. To ensure electrical isolation between the power distribution line and the data line, couplers are typically equipped with an isolation transformer [46].…”

Research on power line carrier communication technology based on intelligent well completion

“…Power line carrier communication is a wired communication method that uses existing power lines to transmit information [4][5][6] . The most important feature of power line carrier communication is that no special communication cable is required, as long as there is a power line, data can be transmitted, while data and power signals are transmitted in the same transmission medium [7] .…”
