Deep Application of Substation Logic Model Handover Based on Digital Twin

To improve the intelligent and digital level of power grid, in allusion to the three aspects of modeling, handover and display of the logical model of substation, a complete set of application research scheme of substation digital handover was proposed. Firstly, the general framework of substation logical model modeling, the database file modeling format and the digital information interaction were researched, and by means of combining the abstract conception in the logical model with the entity concept a rational data structure was designed to realize the full digital expression of the logical model. Secondly, the handover format and import/export interface were expounded in detail, and a digital panoramic logic model information display platform was developed to associate the digital logical model information with the 3D model to display the digital information related to the substation. The proposed research on the handover of logical model of digital design is a supplement to the pure physical model handover of substation and provides the basis for the development of digital power grid.
