Construction and Application of Knowledge Graph in Full-service Unified Data Center of Electric Power System

Abstract

Aiming at the problems of insufficient coordination and sharing of crossservice information and the inadequate utilization of power big data assets, this paper proposes the idea of constructing a power system full-service data knowledge graph combining the background of constructing Full-service Unified Data Center of Electric Power System. Power big data resources can be managed and utilized more intelligently and efficiently by implementing semantic-level connectivity. The application architecture of the knowledge graph in the full-service unified data center is proposed, the key technologies of its construction are analyzed, and a prototype system is built. The system is deployed in the unified data center of State Grid Zhejiang and tested by two typical scenarios of intelligent search and blackout information analysis, the result shows that the knowledge graph can effectively improve the accuracy and recall rate of the search and realize the cross-service information collaboration, optimizing service process.
