水电厂跨区数据融合安全策略及方法研究

Research on the Security Strategies and Methods of Cross-district Data Fusion in Hydropower Plants

目前使用较广泛的基于COMTRADE模型的数据融合策略,受到多元异构冗余数据影响,且数据融合安全性难以保证。为了解决该问题,提出了水电厂跨区数据融合安全策略及方法研究。引入二进制变量和协方差阈值,构建干扰事件判断矩阵;再设计基于事件驱动的滤波处理流程,减少冗余事件的传输。使用双向同时搜索、互相协调的方式,设计基于改进粗糙集的数据融合流程。在此基础上,构建水电厂跨区数据安全融合体系,依据物化视图数据同步方式、触发器方式捕捉数据方式,实现了水电厂数据跨区安全融合。该方案具有完善的理论支撑和实践指导意义。

The widely used data fusion strategy based on the COMTRADE model at present is affected by multiple heterogeneous redundant data,and the security of data fusion is difficult to guarantee.In order to solve this problem,this paper proposes a research on the security strategy and method of cross-zone data fusion of hydropower plants.Binary variables and covariance thresholds are introduced to construct interference event judgment matrix,and an event-driven filtering processing flow is designed to reduce the transmission of redundant events.A data fusion process based on improved rough set is designed by using two-way simultaneous search and mutual coordination.On this basis,the cross-region data security fusion system of hydropower plant is constructed,and the cross-region data security fusion of hydropower plant is realized according to the data synchronization mode of physical and chemical view and the data capture mode of trigger mode.The scheme of this research has perfect theoretical support and practical guiding significance.
