电力通信网是电力系统不可缺少的重要组成部分,一旦其网络中链路发生故障将导致大量重要业务中断,影响电力系统业务调度、生产管理等工作,造成巨大损失。因此电力通信网络生存性和可靠性问题至关重要。本文研究了电力通信网中双链路故障问题,提出一种共享段保护算法,该算法在业务路由选择策略上采用改进Dijkstra算法,综合考虑业务路由链路长度、光缆类型及光纤链路安全系数的综合权重值,为业务工作路由及保护通路计算最优路径,保障网络可靠性。
Power communication network is an indispensable part of the power system. Once the link in the network breaks down, a great deal of important services will be interrupted, which will affect the power system business scheduling and production management, which will cause huge losses. Therefore, the issue of survivability and reliability of the power communication network is very important. In this paper, the problem of dual link failures in power communication networks is studied. A shared segment protection algorithm is proposed. This algorithm adopts improved Dijkstra algorithm in service routing strategy. Considering the link length of service routing, the types of optical fiber cables and the fiber link security factor The comprehensive weight value for business work routing and protection path computing optimal path to ensure network reliability.
