基于非一致性业务均衡的电力通信网路由分配方法

A Power Communication Network Routing Method Based on Non-uniform Service Balance

电力通信网所承载的业务种类多样,一种符合电力生产实际的业务路由分配方法可有效降低电力生产控制类与管理信息类业务的安全风险。文章针对电力通信网的典型结构,综合考虑业务重要度与业务路由配置方法,提出一种非一致性业务路由能量模型。基于该模型,提出了一种基于K最短路径与遗传算法的业务路由分配与优化方法,实现了全量业务场景下的全局路由自动化分配。通过仿真实验证明了该方法在降低电力通信网业务风险上的可行性与有效性。对比传统的最短路径路由分配方法,该方法计算得到的路由在满足电力通信网路由配置原则的基础上实现了非一致性业务的风险均衡,为电力通信网网络优化工作提供了可靠支撑。

Many kinds of services are operating in power communication network. A service route allocation method according to the reality of power communnication network can effectively reduce the security risk of production and management in the power network. Aiming at the typical structure of power communication network, this paper proposes a model of non-uniform service routing, considering the importance of services and the method of traffic routing. Based on this model, this paper presents a service routing allocation and optimization method based on the K shortest path and genetic algorithm （GA）, completes the routing optimization of different scenarios. Finally, simulation experiments proves the feasibility and effectiveness of this method on reducing the operational risk of power communication network. Compared with the traditional routing method, the routing results using the proposed method satistfies the routing configuration principle of power communication network. The riskbalanced services routing can reliably support the electric power comintinication network optimization work.
