光纤差动保护装置的复用通道恢复方法研究
摘要
本文基于电力系统通信ASON网管的建立提出一种用于光纤差动保护装置的复用通道恢复方法
该方法在现有光纤差动保护装置的基础上
通过引入基于ASON技术的SDH和OTN光传输通信网
为光纤差动保护装置提供按需设置的、可靠的备用复用通道
在保护前端设置双通道装置实现保护工作通道与备用通道之间的切换
可进一步提高保护通道的可靠性。
Abstract
A kind of recovery method of multiplex channel for fiber differential protection device based on ASON network management system is proposed. On-demand and reliable standby multiplex channel is provided by introducing optical transmission network SDH and OTN based on ASON network management system on the basis of existing protection devices.Double-channel devices are set in front of protection device to realize the switch between work and standby multiplex channels to further improve the reliability of protection channel.
