Electric power data processing method and system based on knowledge graph

The invention discloses an electric power data processing method and system based on a knowledge graph. The method comprises the following steps: processing power grid knowledge data from a marketing system and a GIS (Geographic Information System) of an acquisition system to obtain structured data, extracting entities from the structured data, establishing an association relationship between the entities and an association relationship between the entities and attributes, and constructing a triple; constructing a knowledge graph from top to bottom based on a triple, transmitting graph structure data of the knowledge graph into a graph database, manually establishing or automatically generating an electric power data rule, and supplementing and reasoning the knowledge graph based on the electric power data rule; based on a power data rule, judging the compliance of a knowledge graph entity relationship, and determining wrong, missing or fuzzy power data existing in the knowledge graph; and for missing or fuzz
