宁夏电力通信同步网的规划研究

针对宁夏电力通信同步网存在部分站点时钟精度低、同步网容灾能力相对较差等问题,基于混合同步方式,对宁夏电力通信网的同步区域进行了重新划分,降低了定时链路的长度,将最长的定时链路从 14 跳降低为 6 跳,确保每个站点至少具备一路备用时钟。应用结果表明:混合同步方案利用二级时钟有效提高了宁夏电力通信同步网的时钟精度和容灾性能。

Planning of Ningxia power communication synchronous network

Aiming at the problems of low clock accuracy of partial sites and weak disaster recoverycapability in Ningxia power communication synchronous network,based on mixed synchronousscheme,redesigns the synchronous zone of Ningxia power communication network,reduces thelongest timing link from 14 hops to 6 hops,ensures every site has one backup clock at least. Theapplication result shows that the mixed synchronous scheme using the second level time-clock canimprove the clock accuracy and disaster recovery capability of Ningxia power communicationsynchronous network.
