【摘要】 电网发生极端灾变时常因OPGW光缆损坏而引起通信中断,进而引发线路主保护乃至线路退出运行,广域保护也会发生类似问题。本文基于蚁群算法,提出广域保护迂回通信通道的重构方案。文章介绍了蚁群算法的基本原理,分析了广域通信网络的延时,在此基础上,利用网络已知数据,详细提出了迂回通信通道重构方案。进而利用MATLAB对IEEE 14节点,在不同链路发生通信中断时迂回通信通道的重构进行了仿真分析,得出最佳迂回路由表。结果显示,该方案所得迂回通信通道为最优通道,可作为广域保护的后备通信通道。更多还原

【Abstract】 When extreme grid disasters occur,communication outage is often caused by OPGW damage so that the main protections and indeed lines will be failed.Also in this case,similar problems can occur in the wide area protection(WAP).In this paper,a circuitous channel reconstruction scheme based on ant colony optimization of WAP is proposed for the purpose of solving the above problem.In this paper,fundamental principle of ant colony optimization is introduced and the delay of Wide area communication network is analyzed.Based on these,scheme of setting up circuitous communication channel is raised.When communication of the line in IEEE 14 is interrupted,the simulation of this scheme based on MATLAB is introduced and the best circuitous routing table is got.The simulation results show this scheme can get the best circuitous communication channel and can be used as backup communications channel of WAP.更多还原
