光纤通道传送线路保护信号的方式及其分析

Way of Protective Relaying Signals Transmission through Optical Channel with Its Analysis

简介光纤通道纵联保护系统的组成,以及浙江省电网用光纤通道传送线路保护信号专用和复用的2种方式。同时分析了继电保护信号对传输延时、误码、同步质量要求的影响因素,并结合电网工程,利用SDH光纤系统传输保护信号,进行了500kV线路采用的复用光纤通道保护实例计算。

The paper briefly introduces the composition of the optical line protection system and 2 ways (special and complex application) to transmit the line protection signals through optical channels in Zhejiang Power Network. At same time it analyzes the factors effecting on requirements for transmission relay, error code and synchronous quality. Also a calculation example is given for a 500 kV line with a complex optical channel protection in combination with a network project and transmission protection signals of SDH optical system.
