摘要
电力频率同步网是保障电力通信网正常运行的重要支撑网络,进行公司频率同步网优化改造可以提升电力通信网可靠程度。文章论述了公司频率同步网优化改造的背景,梳理了公司频率同步网的运行现状,分析出存在的问题,根据存在的问题提出了公司频率同步网目标网络,并对节点时钟优化改造时设置的基本要求、节点优化原则和定时链路优化原则进行了论述。
Electricity frequency synchronization network is an essential backbone to support the normal operation of power communication network. Optimization and upgrade of the company frequency synchronization network can improve the reliability of the power communication network. In this paper, the background of the frequency synchronization network upgrade is presented. The current operation status of the company frequency synchronization network is sorted out. Consequently, the existing problems are derived. Based on the existing problems, a target company frequency synchronization network is proposed. Furthermore, the basic requirements for node clock setting, as well as the optimization principles for node and the timing links, are illustrated in this paper.
