电力光纤通信网络的最佳路径选择

Path Optimization of Electric Power Optical Fiber Communication Networks

为解决电力光纤通信网分期分批建设导致的网络资源利用率偏低、网络结构不尽合理等问题,文章综合考虑电力通信网的业务特点、通信组网所需的纤芯数以及网络成本最优等因素,对架设于不同电压等级输电线路上光缆可靠性赋予不同的权值。以此为约束条件改进了Floyd算法并开发了计算软件,用于寻找电力通信网最佳路径,进行组网设计。福州市区东南部的应用表明,文章提出的算法与实际情况相吻合。

To address the problem of low resource utilization efficiency and unreasonable network structure of current electric power optical fiber communication networks, which is caused by construction in separate periods, this paper carried out path and networking optimization for power communication networks with consideration of network characteristics, the number of fibers required and minimal network cost. Different weights are given for fiber cables on different voltagelevel lines. Considering these constraint conditions, an improved Floyd algorithm is presented to find out the best path between each node pair for power optical fiber communication networks, and software is developed for network design. Its application to south-east power optical fiber communication networks of Fuzhou in China demonstrates the effectiveness of our alzorithm.
