Real-time power grid state safety checking method based on digital plan model

The invention relates to the technical field of power grid state safety checking, in particular to a real-time power grid state safety checking method based on a digital plan model. Comprising the following steps: constructing a pre-arranged plan model based on digitization; performing security check based on the digital plan model; safety checking considering the maintenance risk; and security check considering real-time risks. According to the design of the invention, cross-professional and cross-system business collaboration can be supported from business, and the overall scheduling operation management and monitoring level is improved; dynamic deduction can be carried out in a visual simulation function, rules and historical data in a real-time risk knowledge base are used as supports, the risk identification efficiency and the auxiliary analysis safety are improved, various decision-making auxiliary bases are provided for power grid accident handling of dispatching and regulating operators on duty, and t
