Knowledge-Graph Construction Method of Operating Fault Feature Library for New Power Load Management System

The new power load management system is a key supporting system to promote the construction of new power system. To solve the complex issue of knowledge graph construction applied in new power load management System, this paper proposed a knowledge-graph construction method of the operating fault feature library. Firstly, the principle of the top-down construction method of knowledge graph is analyzed method. Then, the proposed knowledge-graph construction method of the operating fault feature library is depicted in detail consisting of five steps, which are data collection, conceptual modeling, data preprocessing, knowledge extraction and knowledge storage. Finally, case analysis is carried out to verify the feasible performance of the proposed method, in which the Neo4j graph database is used to visualize the knowledge graph of the operating fault feature library, and the fault diagnosis of an auxiliary decision-making function is implemented.
