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

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.
