基于业务临近度的电力通信网脆弱性分析

Service proximity based vulnerability analysis of power communication network

电力通信网脆弱性分析对确保电力系统安全运行和加强电网健壮性具有重要意义。以网络端到端时延理论为基础,建立基于业务临近度的电力通信网的脆弱性分析和评估模型。通过分析电力通信网的运行情况和业务分布,估算出端对端的传输时延、业务临近度和相邻节点的业务临近度相关性,建立业务链和节点的脆弱性分析模型。以IEEE-30节点系统为例进行仿真,完成对通信网络的脆弱性分析。对节点和业务链进行脆弱性排序,结果表明节点时延、业务分布和节点相关度三者与电力通信网的脆弱性密切相关。

The vulnerability analysis of power communication network has important significance to ensure the safe opera-tion of the power system and strengthen the network robustness.On the basis of the network end-to-end delay theory,a service proximity based vulnerability analysis and evaluation model of power communication network is established.By analyzing the opera-tion condition and service distribution of the power communication network,the end-to-end transmission delay,service proximity and service proximity correlation of adjacent nodes are estimated,and the vulnerability analysis model of service chain and node is established.The IEEE-30 node system is taken as an example for simulation,with which the vulnerability analysis of commu-nication network is conducted,and the vulnerability of nodes and service chains are sorted.The results show that the node de-lay,service distribution and node correlation are closely related to the vulnerability of power communication network.
