The comprehensive evaluation of distribution network is of great significance to improve the weak links of distribution network, improve the performance of power grid and guide the development planning. In the information age of big data, the amount of knowledge is growing explosively. In order to facilitate the staff to learn and master the comprehensive evaluation knowledge of distribution network, and to be able to perceive the operation status of distribution network in an all-round way, this paper combines the traditional comprehensive evaluation method of distribution network with the knowledge mapping technology which has the characteristics of interconnection, openness, structure and visualization. A comprehensive evaluation method of distribution network based on knowledge graph is proposed. The graphs are constructed from the schema layer and the data layer by combining the top-down and bottom-up methods. The graphs are divided into entity graph, evaluation logic graph and case graph. The core construction technology is analyzed and combined with the actual evaluation scenario, the paper provides ideas for the implementation of each link of the evaluation process. Finally, based on the above method, the evaluation logic graph in the actual evaluation case is displayed to verify the feasibility of the method.
