Multi-data integration and application integrated system and method based on electric power big data

The invention relates to the technical field of power data management, in particular to a multi-data integration and application integrated system and method based on power big data, and the method comprises the steps: collecting all power data generated in the operation process of a power plant every unit period; acquiring corresponding management data categories to which the electric power data belong according to a preset electric power data management rule, and storing the electric power data subjected to corresponding category marking into an electric power database; constructing power data topological nodes, and carding a power data topological network of the power database; respectively calculating a feature retrieval index of the power data of each management data category in the power database; feature categories are screened out, the associated retrieval category of each feature category is recognized and judged, and a feature information range on which a progressive retrieval association relationsh
