智能电网虽然提升了电力体系的智能化水平与信息化水平,但也增加了电力数据体量与交互行为数量,这对电网通信性能提出了极高的要求.若是暂态通信状态异常,容易导致电力数据的缺失,影响智能电网的稳定运行,提出基于数据挖掘的智能电网暂态通信安全状态感知技术研究.选取合适的暂态通信安全状态感知指标,采用多种智能传感器获取感知指标数据,并识别与填补缺失指标数据,以此为基础,应用并行聚类算法深度挖掘安全状态感知指标数据,采用层次分析法确定安全状态感知指标的权重数值,搭建智能电网暂态通信安全状态感知模型,制定暂态通信安全状态感知规则,从而实现暂态通信安全状态的感知.实验数据显示:在不同实验工况背景下应用提出技术获得的暂态通信安全状态数据挖掘深度系数最大值为0.96,暂态通信安全状态感知结果与实际结果保持一致,充分证实了提出技术的应用性能更佳.
Based data mining transient communication security state perception technology for smart grid
Although the smart grid has improved the intelligence and informatization level of the power system,it has also in-creased the volume of power data and the number of interactive behaviors,which poses extremely high requirements for the communi-cation performance of the power grid.If the transient communication status is abnormal,it can easily lead to the loss of power data and affect the stable operation of the smart grid.Therefore,a data mining based technology for sensing the transient communication security status of the smart grid is proposed.Select appropriate transient communication security state perception indicators,use mul-tiple intelligent sensors to obtain perception indicator data,and identify and fill in missing indicator data.Based on this,apply paral-lel clustering algorithm to deeply mine security state perception indicator data,use Analytic Hierarchy Process to determine the weight value of security state perception indicators,and build a smart grid transient communication security state perception model,Develop transient communication security state perception rules to achieve transient communication security state perception.The experimental data shows that the maximum depth coefficient of transient communication security state data mining obtained by applying the proposed technology under different experimental conditions is 0.96.The perception results of transient communication security state are con-sistent with the actual results,fully confirming that the application performance of the proposed technology is better.
