Abstract:
Digital twin technology is considered the fundamental to realize the digitization and intelligence transformation for power industry. In this paper, a general module structure, which is composed of ontology model, data model, 3D model and simulation model, is used to build the digital twin model for a physical entity in power substation. The knowledge graph based on the graph database is built to organize the different modules in a digital twin power substation and reflect the various connections between them. Furthermore, a power substation simulation method is proposed to support the virtual operation based on the real time status of the substation. Finally, a prototype digital twin system for power substation is built. The system can provide a novel platform for immersive status display and operation process simulation, which can be applied to support the substation situation awareness, operator training and operation plan verification.
