|Title:||Low-voltage power line communications for DC power distribution network||Authors:||Zhou, Yingying||Keywords:||DRNTU::Engineering::Electrical and electronic engineering||Issue Date:||2014||Abstract:||The transformation to smart grid calls for high speed bidirectional communication technologies to establish the reliable communication architecture. As a potential candidate , power line communication (PLC) shows promising advantages of saving cost by eliminating the need for additional serial-communication wiring. The object of this project is to build a communication system with an implementation of Narrow band Power line communication (NB-PLC) technology working on CENELEC -A band. To achieve a desirable performance, OFDM (Orthogonal Frequency Division Multiplexing) system with PRIME specification is adopted to overcome the technical issues over power line channel. Unlike most of the researches focusing on AC power line, the interest of the project is focused on 24 V DC bus. It is an embedded system co-designed with hardware and firmware which realizes the two-way point-to-point communication. Particularly, the problem of multiple nodes networking is considered during the hardware design.
