摘要
针对电力光纤迂回通道传输的继电保护业务,提出了基于安全性的最佳路径选择方法。介绍了光纤通道方式及性能指标,强调了从安全性的角度为继电保护业务配置最佳路径的必要性。在此基础上,改进了已有的Dijkstra算法用于选路,所提算法充分考虑了电力光纤通信网节点和链路的安全性度量值。为避免某些链路过载带来安全风险,通过动态权值更新函数调整链路权值。通过网络实例验证了新算法的可行性和有效性。
A optimal path selecting method based on security is proposed for relay protection services of optical-fiber circuitous channel. Firstly, the requirements and types of optical-fiber relay protection channels are described, and the necessity of configuring the optimal path is analyzed from the security perspective. Secondly, an improved Dijkstra algorithm is used to select paths, considering the security measure of nodes and links. For links security balancing, a function is used to adjust the weights of the links. Finally, examples verify the feasibility and effectiveness of the new algorithm.
