| 摘要: |
| 电力通信传输网的安全性直接关系到电力系统的稳定运行。针对风险评估系统指标体系繁杂、评估一次需要时间比较长的问题展开研究，构建了增加属性约简功能的风险评估模型。在初始指标体系的基础上，运用基于重要度的粗糙集属性约简算法得到精简指标体系，然后根据网络节点风险计算流程及模型计算出风险评估结果。实验验证了改进模型能有效地缩短系统评估时间，最后设计实现了电力通信网风险点分析与控制系统。 |

| Abstract: |
| The security of power transmission network is directly related to the stable operation of the power system. In response to the complexity of indicator set of risk evaluation system and intensive time-consuming of a single risk evaluation process, a risk evaluation model added attribute reduction function is proposed. On the basis of the initial index system, the index system is reduced by using the rough set attribute reduction algorithm based on importance degree, and then the risk assessment results are calculated according to the network node risk calculation processes and models. The experimental results show that the improved model can effectively shorten the system evaluation time, and finally the risk point analysis and control system of power communication network is designed and implemented. |
