Knowledge graph technology can make full use of the vast amount of data stored in power grid to describe the core elements of power equipment in a structured form. So as to form a professional knowledge system of power equipment, effectively use the value of it, and promote the intelligent development of power grid. This paper proposes a construction method for the knowledge graph of power equipment based on ontology modeling, which can extract and integrate equipment data from massive historical data accumulated by power grid, and realize the creation of power equipment knowledge graph through knowledge modeling, knowledge extraction, knowledge fusion and other links. Finally, the relevant process and visualized display are demonstrated through an example. The results show that the knowledge graph of power equipment can effectively integrate the information in the power grid, realize the unified description of power equipment data, and provide a basis for the research of intelligent power grid.
