Organizational Description System for Digital Twin of Distribution Network Equipment Based on Object-oriented Equipment Model

Digital twin is a mathematical model of a physical object that can accept real-time data and evolve in real time. The fundamental technology underlying digital twin technology is modeling and simulation. For a distribution network with complex structure and numerous devices, the construction of digital twins is of great significance for equipment management and system analysis. This paper first introduces the object-oriented modeling method and presents an object-oriented equipment model (OEM). Subsequently, an organizational description system for digital twin of distribution network equipment based on object-oriented equipment model is designed, and the concrete implementation method is introduced. Finally, by comparing with the simulation results of PSCAD software, the accuracy of the electromagnetic transient (EMT) simulation program, one of the applications of the proposed system, is verified.
