电力线高速数据通信技术的发展及未来

Development and future of power line high-speed communication

电力线高速数据通信技术(PLC)在电力系统通信中占有重要位置。文章首先对该项技术在国内外的研究和应用现状进行了回顾,介绍了我国PLC方面的主要工作成果和国内外PLC关键技术发展情况(包括信道模型、噪声特性、信道容量、调制技术及MAC层协议等)、标准的进展情况以及尚存在的主要问题。论述了PLC技术的发展趋势,以及需要进一步开展的工作。

PLC is important in the electric power communication system. This paper gives an overview of the development in power line communication （ PLC ） and their status of applications in China and abroad. The major research works about PLC in China, and developments of PLC key technique （included channel model, noise characteristic, channel capacity, modulating technique and MAC layer protocol etc. ）, standards and existing primary problems are introduced. The developing trend of PLC and the works that need to be launched further are discussed.
