The current multi-source data-based power network security event processing system builds a security event processing platform by combining multiple data sources, which leads to low processing efficiency of the system due to the lack of refinement of the source data. In this regard, the power network security event processing system based on correlation analysis is proposed. Combined with alarm correlation analysis theory, network fault location and alarm filtering analysis are realised, and alarm data is pre-processed. According to the alarm management requirements, the processing process of power network security events is constructed. In the experiments, the processing efficiency of the proposed power network security event processing system is verified. The results of the experimental analysis show that the processing system constructed using the proposed method has a low packet loss rate and high processing efficiency.
