摘要
利用中压电力线实现高速数据通信，目前在国内尚属一项空白。如果能够充分运用农村高覆盖率的中压配电网，进行远距离PLC高速通信，将推进农村信息化建设和开创电力工业新的经济增长点。文章对中压（10kV）配电线路的高频信道特性进行了测试研究，并以河北省某乡一座35kV变电站的10kV出线为测试对象，自行搭建测试系统，进行了噪声特性、衰减特性、阻抗特性方面的测试，掌握了相应数据资料。笔者通过分析，提出了选用2—12MHz作为实现中压PLC远距离高速数据传输工作频段的建议。
Nowadays, there is no practice of transmitting high speed data via medium-voltage （MV） power line in China. It will be a great contribution to the rural informationazation and will be a new economy growth point for power industry if MV distribution network in rural areas could be used for high-speed data transmission over long distance. Based on a trail system in Heber, this paper analyzes the high frequency channel performance of 10 kV distribution power lines, including the test for noise, attenuation and impedance characteristics. The suggestions are also made by the paper that the,frequency band from 2 MHz to 12 MHz is selected as the working band for MV-PLC long distance and high-speed data transmission.
