摘要
针对电力通信网业务流多采用各站点与中心站之间单一的点对点通信模式,易导致由于中心站故障引发全网瘫痪风险的问题,提出对电力通信网络拓扑结构进行优化,将单一网络划分为2个或多个网络,并由中心站的若干套设备分担业务的建设方案。为优化工程的实施,解决部分业务在设备间的切换和完成网络重组是关键。为此,文章介绍了串联切割法和并联切割法,叙述了切割操作对业务的影响及重组网后的运行效果,并对深圳电力通信网结构优化成果做了介绍。
Point-to-point communication mode between various substations and the central station is adopted by power telecommunications network. With this mode, the failure from central station may cause the breakdown of the whole network. In this paper, the author points out that an optimized power communications network topology is needed, i.e. the network is divided into two or more subnets and the equipment in central station shares the services. The author also introduces the incision method both in series and parallel connection way, and the influence and the effect of network reconfiguration. Finally, the paper introduces the optimizing achievement of Shenzhen electric power communication network.
