Power system risk assessment method and equipment based on power data analysis

The invention relates to a power system risk assessment method and device based on power data analysis, and the method comprises the following steps: S1, selecting a time delay parameter based on the time series data of a power system, and obtaining a dynamic structure of the power system; s2, the change rate of the key data points is calculated, the change rate of the key data points is calculated, and the stability index of the power system is obtained; s3, analyzing the transmission loss and the frequency response, identifying and classifying potential risk modes, and obtaining a risk early warning signal; s4, constructing a conditional probability network, and associating the performance degradation data points of the power equipment with power system behaviors to obtain an equipment risk association network; s5, obtaining an equipment state behavior record, and combining the real-time monitoring data to obtain a power system behavior prediction result; and S6, calculating a hierarchical health score of t
