Power Network Security Situation Awareness Method Based on Heterogeneous Data Sources

With the process of digitalization and intelligence of power network, the security problem of power network has become increasingly prominent. Aiming at the heterogeneity and diversity of power network security situational awareness data, in order to improve the performance of power grid security situational awareness, a power grid security situational awareness method based on heterogeneous data sources is proposed. Using heterogeneous data sources to obtain the associated distribution set of power network security situation information, and obtaining the identification result of power network information according to the network detection statistics of power grid system, so as to collect power network security situation information; The architecture of power network security situation awareness is constructed, and the static security and dynamic security indicators are obtained to realize power network security situation awareness. The experimental results show that this method has strong perception ability, achieves the best optimization effect in the shortest time, and can perceive the security situation of power network.
