电力通信骨干网节点重要度评价方法

Node importance evaluation strategy on electric power communication backbone network

由于电力通信骨干网中的某些节点对整体网络可靠性有着重要影响,需要确定网络中关键节点的位置并提供相应等级保护。综合考虑通信节点在网络拓扑中的分布特性,选取网络链路带宽作为网络权值建立电力通信骨干网模型,利用节点在电力系统中的权值作为修正系数,提出了电力通信骨干网节点重要度的一种评价方法。利用电力系统节点权值进行的修正,使节点重要度的评价更加全面,提高了节点重要度评价方法的实用性。以电力通信骨干网模拟拓扑为例进行仿真实验,实验结果验证了该方法的有效性。

Some of the important nodes in the electric power backbone communication network have an important im-pact on the overall network reliability, and thus the location of the key nodes in the network and further develop protec-tion methods are needed. In this paper, a node importance evaluation strategy is proposed, in which the distribution of communication nodes in the network topology is comprehensively considered. By using this strategy, the model of elec- tric power communication backbone network is built, with bandwidth considered as network weight, and weight of node in the electric power system as correction coefficient. Corrected by node weights of the power system, the node impor-tance evaluation strategy becomes more comprehensive and practical. The topology of electric power communication net-work is used in simulation and the results show that the strategy is efficient.
