摘要/Abstract

摘要： 识别电力通信网中的关键节点并对其进行重点保护，对提高网络整体可靠性有重要意义。在网络拓扑层，计算节点失效后电力通信网自然连通度的变化，得到节点拓扑重要度（NTI）。针对电力通信网业务性能指标要求不同给出了业务重要度的评价方法；融合业务信息与拓扑信息定义了网络加权自然连通度，提出了节点融合重要度（NCI）的概念，以实现电力通信网关键节点的识别。以某地区电力通信网为例，将所提方法与其他传统方法进行仿真对比，实验结果表明所提方法的合理性和有效性。

关键词: 电力通信网, 自然连通度, 节点拓扑重要度, 业务重要度, 节点融合重要度

Abstract: The identification of critical nodes of the power communication network as well as the corresponding protection mechanism have crucial impacts on the system-wide reliability. In this paper, the Node Topology Importance (NTI) is obtained by calculating the rate of natural connectivity of power communication network after one node being destroyed. Then, an evaluation method is proposed according to the requirement of power communication network services. The weighted natural connectivity which fuses the node business information and topology information is defined, accordingly Node Combining Importance (NCI) is proposed to realize the excavation of key node. The effectiveness of the proposed methods is verified by case studies on a real-world regional power communication network.

Key words: power communication network, natural connectivity, node topology importance, business importance, node combining importance
