摘　　要：由于西藏电力通信网的发展相对滞后,西藏电力公司利用光纤通信复用继电保护、稳控通道的水平还处于初期阶段。文章简要介绍了西藏电力光纤通信网的现状,以及网内所使用的继电保护、稳控传输通道的种类及特点,并从光纤通信网络的结构、复用通道管理机制和通道双重化3个方面对继电保护、稳控传输通道存在的安全问题进行了详细分析。The utilization of optical fiber communication network as a channel to transmit multiplexing relay protection and stability control signals is in an elementary phase since the development of Tibet＇s electric power communication network lags behind other provinces. This article introduces the present situation of Tibet electric power optical fiber communication network and describes the types and characteristics of relay protection and stability control channel in this network. It also analyses the safety of relay protection and stability control channel in detail based on structure of optical fiber communication network, management mechanism of multiplexing channels and duplex channel.
