A Knowledge Graph Construction Method of Multi-source Heterogeneous Data for Tianjin Chengnan Power Plant Station
The relationship between power substations and their equipment has been complicated by the new genera-tion of power systems,whose data presents the characteristics of multi-source and heterogeneity.To obtain a global model,a knowledge graph construction method for Tianjin Chengnan power substation is proposed.Firstly,the feature analysis and knowledge extraction of multi-source and heterogeneous data are carried out,which is adopted to form the entity relation database and fault information database of power system.Secondly,the knowledge graph structure based on Tianjin Chengnan Power substation is designed.The knowledge graph is constructed to form an integrated data platform,which covers the entity relationship between station and equipment.Finally,the application of the knowledge graph is briefly analyzed.The results show that the knowledge graph of power substation can cover all the equipment and large data.
