Intelligent power distribution network online risk assessment method

The invention discloses an intelligent power distribution network online risk assessment method. Through comprehensive analysis of online data and historical data, an assessment mathematic model is established, and a visually-displayed risk assessment diagram is finally formed. According to targeted power grid data collection and through comprehensive analysis of the online data and the historical data, the data can be monitored in real time, analysis models expanded on the basis of a large number of existing database devices of a power grid are easy to establish, according to the actual condition of the power grid, the risk pre-warning level is instructed simply, visually and clearly in the mode that a two-dimensional chart and different colors are matched, and therefore practicality is high. Prediction models of a system can be edited according to different formula computing methods, flexibility is large, a data report can be updated and stored through a network platform, the current requirement of a user is met, and the method can adapt to changes of development and management modes of an industry and updating of the technology.
