摘要
由于电力通信网与电力网络的相互依存性,电力通信网的关键节点对整体电力网络的可靠性有较大影响。文章提出一种基于电力通信网节点业务重要度和传输能力的节点重要度衡量指标。通过构建电力通信网容量矩阵和网络业务联络矩阵计算节点各类业务流介数,将各类业务流介数与业务权重加权得到节点重要度评价指标。该指标可应用于电力通信网规划阶段,解决了该阶段业务流量未知的问题,能够更加准确地辨识关键节点。结果表明,提出的指标具有较高的辨别关键节点的能力。
Due to the interdependence of power communication network and power grid, the critical nodes of power communication network have great influence on the reliability of the whole power network. In this paper, a node importance measurement index based on the importance and transmission capacity of power communication network nodes is proposed. Through the establishment of the power communication network capacity matrix and the network service contact（NSC） matrix, the importance measurement index of the nodes is calculated based on the weighting of the service flow and service weight. This indicator can be applied to the planning phase of the power communication network, which may solve the problem that the traffic flow is unknown at that stage and can identify the critical nodes more accurately. The simulation results show that the proposed index has a high ability to identify key nodes.
