摘　　要：基于风险评估基本理论,结合网络配置、业务故障状态及危害度分析,建立了一种改进的电力通信网风险评估模型。该模型可用于量化故障引起的业务损失程度及网络风险水平。通过构建网络拓扑验证了方法的可行性,并与传统风险评估算法进行对比分析。This paper based on the basic theory of risk assessment, combined with the network configuration, business failure status and criticality analysis, an improved risk assessment model of electric power communi- cation network is proposed. The model can be used to quantify the degree of business loss, as well as the level of network risk caused by failure. The feasibility of the method is verified by constructing the network topolo- gy, and compared with the traditional risk assessment algorithm.

关 键 词：风险评估 业务损失 故障模式影响与危害度分析
