内蒙古电力通信网时钟同步系统优化改造

Reconstruction and Optimization of Clock Synchronization System in Inner Mongolia Power Information and Communication Network

对内蒙古电力通信网的时钟同步系统进行分析,发现现有时钟同步系统主要存在3个问题:SDH传输网络的时钟分布不合理、同步定时设备利用率较低、没有统一的时钟同步网管系统。针对存在的问题,提出对同步定时设备进行改造和升级,并对SDH传输网进行调整和优化。改造后,时钟同步系统的稳定性和可靠性得到提高,为电网的安全稳定运行提供了保证。

This article analyzed the clock synchronization system in Inner MongoliaPower Information and Communication Network. Through inspecting the clock signals of allthe transmission equipment in every sub- transmission network management systems, theclock synchronization system had three major problems of the unreasonable distribution ofthe SDH transmission network clock, the low efficiency of the synchronized timing devices,and the non- uniform network management system of the clock synchronization system.Considering of the problems and drawbacks in this system, upgraded the synchronizedtiming devices and optimized the SDH（Synchronous Digital Hierarchy） transmissionnetwork. The stability and the reliability of the new clock synchronization system wereimproved. Meantime, the stability and the safety of the power grid operation could beguaranteed.
