| Abstract: | 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 protection channel in optical network with 64 kbit/s, E1 and fiber multiplexing, and discusses the security problem occurring in channel multiplexing. Some suggestions are also put forward in the paper for future network planning. |
