摘　　要：介绍了河南省电力通信网络概况,对电力线载波、微波和光纤这3种主要传输继电保护信号的方式进行了比较,重点分析了光纤网络中继电保护通道64kbit/s、E1和光纤复用的特点。最后,对复用通道存在的安全问题进行了探讨,为今后在网络规划中对保护通道的要求提出了建议。This paper introduces the general situation of electric power communication network in Henan Province. It compares three kinds of transmission modes for relay protection signals, i.e. PLC, microwave and optical fiber. It analyzes the features of relay pro- tection channel in optical network with 64 kbit/s, El and fiber multiplexing, and discusses the security problem occurring in chan- nel multiplexing. Some suggestions are also put forward in the paper for future network planning.
