针对风险评估算法精度较低,实际响应时间较长的问题,提出电力网络风险IP快速阻断与预警方法设计。从电力网络中的IP信息中识别网络IP风险,综合基础架构评价、可靠性评价以及历史评价三部分,分析操作响应时间,构建风险评估模型;计算风险值,依据风险IP分析结果,接收高风险IP预警,批量阻断风险IP。在响应时间优化的基础上,实现风险IP快速阻断与预警。实例测试结果表明:文中设计方法的预警性能明显优于其他方法,在相同的测试环境中,预警精度分别提升了16.3%和10.8%。

In order to solve the problems of low accuracy and long response time of risk assessment algorithm,a fast blocking and early warning method of power network risk IP is proposed.IP risk of network is identified from the IP information in the power network,and combined with infrastructure evaluation,reliability evaluation and historical evaluation,operation response time could be analyzed and the risk assessment model is constructed.Then,the risk value is calculated,and based on the analysis resullt of the risk IP,high risk IP warning would be received and blocked.On the basis of response time optimization,risk IP’s rapid blocking and early warning can be realized.The experiment results show that the early warning performance of the design method is significantly better than that of other methods,and the early warning accuracy improved by 16.3%and 10.8%in the same test environment.
