摘　　要：随着电网规模的扩张,网络结构复杂度提升,电力业务多样化,网络业务负载激增,电网安全运行对电力通信网在抗毁性、可靠性等方面提出了更高要求。准确评估电力通信网中的高风险节点,提前对高风险节点采取保护措施,可以防止高风险节点受到攻击后网络的拓扑结构或电力业务传输受到较大影响。从网络结构以及电力业务两个维度分析电力通信网中节点的风险性,构建指标量化节点失效造成的影响,使用信息融合算子融合两个维度下得到的量化值,完成电力通信网节点风险评估。仿真结果表明,该评估方法能够准确量化电力通信网节点的风险性。With the expansions of the power grid,the complexity of the network structure,the diversification of power services,and the surge in network traffic load,the safe operation of the power grid puts forward higher requirements on the power optical fiber communication network in terms of survivability and reliability.The high⁃risk nodes in the power optical fiber communication networks should be evaluated exactly,and the high⁃risk nodes should be protected in advance to prevent the high⁃risk nodes from being affected by the topology of the network or the transmission of power services.The risk of nodes in the power optical fiber communication network was analyzed from two perspectives of network structure and power services.The indicators to quantify the impact of node failure are created and selected.The information fusion operator was applied to fuse the quantized values obtained from two perspectives to complete the risk assessment of the power optical fiber communication network.The simulation results show that this assessing method can accurately quantify the nodes risk in power optical fiber communication networks.
