广域保护通信重负载下迂回路径重构算法
|
摘要
在恶劣环境或人为破坏等情况下,广域保护通信网络可能会发生线路中断的情况,这也是阻碍广域保护技术得以广泛应用的重要因素之一。以重负载时的广域保护通信网络为研究对象,为保证中断信道上的数据不间断传输,针对特性不同的GOOSE报文和SV报文设计不同的路径重构算法。针对时延要求、重要程度均最高的GOOSE报文,采用单一迂回路径重构算法。在此基础上,对数据量较大的SV报文,设计一种分流迂回路径重构算法。该算法的关键在于考虑了迂回路径中短板信道的带宽可用裕度,将站域所有SV报文分成多股,基于短板信道的带宽裕度比,确定最佳分流系数,从而保证重载通信系统分流后网络负载较为均衡。通过OPNET仿真软件搭建IEEE14节点通信仿真模型,对迂回路径重构算法的延时和均衡性进行了仿真验证。
Communication network of wide area protection may be interrupted because of severe environment or artificial damage. It is also one of the factors which affect the application of wide area protection. In order to maintain the transmission of the data on the interrupted channel, this paper designs different paths reconstructing algorithms for GOOSE and SV respectively by taking communication network of wide-area protection when heavy load as an object. Due to the importance of GOOSE and its high requirement for real-time, a single roundabout path reconstruction algorithm is proposed. As for SV whose amount of data is large, a reconstruction algorithm of shunt paths is proposed. It is the key that the available margin of bandwidth of weakest channel among the circuitous paths is considered in the algorithm. All the SV are divided into several streams according to the ratio of margin to entire bandwidth of the weakest channel, so that the balance of communication network with heavy load can be ensured after dividing. Finally, IEEE14 nodes network is built with OPNET. Delay and balance of the reconstruction strategy of circuitous communication paths are tested.
