In the substation simulation system, in order to facilitate self-learning and knowledge assistance, as well as the transfer of information between different simulation systems, it is necessary to configure the retrieval and query function of substation equipment simulation information for all types of information generated during the simulation process of substation equipment. This article proposes a construction and retrieval method of power substation simulation information knowledge graph based on physical relationships in the field of substation equipment simulation technology. Firstly, the simulation information of substation equipment is obtained, and then the knowledge graph of substation equipment simulation information is constructed based on physical equipment, systems or their components. Next, the ontological relationships and ontological attributes of the knowledge graph are extended and reasoned. Finally, the retrieval and query of substation equipment simulation information are carried out using the graph structure. Taking the simulation information of double-wound oil-immersed transformers as an example, this article illustrates the construction and retrieval method of power substation simulation information knowledge graph based on physical relationships in the field of substation equipment simulation technology.
