Application of Knowledge Graph in Operation and Maintenance of Power Transmission Equipment

Effective utilization and management of the massive data of transmission and transformation equipment is an important direction for the development of new power system informatization. Mining the O&M data of transmission and transformation equipment and perceiving its situation can ensure the safe and stable operation of these equipment. Therefore， this paper introduces knowledge graphs into the field of the transmission and transformation equipment O&M field. First， the data and existing problems of the transmission and transformation equipment O&M service are analyzed. Second， the data fusion and clustering technology of transmission and transformation equipment and the construction technology of the O&M knowledge graph are introduced. Third， combined with the O&M characteristics of transmission and transformation equipment， the typical application scenarios of the knowledge graph in the O&M service of transmission and transformation equipment are summarized. Finally， the current research hot spots are analyzed， the key issues of knowledge graphs in the transmission and transformation equipment O&M field are discussed with the development prospect of this field presented. The use of knowledge mapping in the field of transmission and substation operation and maintenance not only improves the maintenance efficiency of the enterprise，but also reduces the manpower cost.
