A Digital Twin System and Modeling Method for All-in-one Station Grounding System

At present, the electric power system is under great operational pressure, especially in terms of grounding technology for electrical equipment, because grounding technology belongs to a class of traditional technical methods in electrical equipment, so the operation level of grounding technology is improved in order to maintain the effectiveness of electrical equipment in grid planning. To address this issue, this paper proposes an all-in-one station grounding system after analyzing the actual situation, analyzing and integrating multiple grounding technologies and establishing a model through digital twin technology. Firstly, through the interaction between the physical system of grounding network and the digital twin system, the all-in-one station grounding network information model is applied in the whole life cycle of the whole link. Then, the fusion of offline data, online data and simulation data is realized and utilized to realize grounding network situational awareness, abnormal state diagnosis and trend prediction. Finally, the digital twin model of grounding network is established. Simulation is verified.
