摘要

电力骨干光传送网是电力部门生产调度、信息通信的基础

提高其生存性是近几年的研究热点。文章结合电力骨干光传送网对保护的需求

提出了一种SDP（基于Suurballe算法的专有保护）算法。仿真结果表明

SDP算法比传统的DDP（基于Dijkstra算法的专有保护）算法有更低的阻塞率和资源占用率

适用于需要专有保护的电网业务。

Abstract

Electric power backbone optical transmission network is the basic infrastructure for power dispatching and information exchange by electric power companies and improving its survivability is the focus of research in recent years.In connection with the requirement of protecting electric power backbone optical transmission networks

this paper proposes a Suurballe algorithm-based Dedicated Protection（SDP）algorithm.Simulation results indicate that SDP has lower blocking probability and resource occupancy rate than the traditional Dijkstra algorithm-based Dedicated Protection（DDP）algorithm

more suitable for the grid services that need dedicated protection.
