Research on 5G UAV Smart Grid Inspection Technology Based on Digital Twin

At present, 5G, UAV, Beidou Positioning, artificial intelligence and digital twin technology are accelerating the deep integration with industrial departments such as transmission grid. This paper studies the intelligent application of 5G UAV based on digital twin in transmission grid, especially the key technologies of transmission line inspection, digital twin technology and 5G UAV technology, Through the research, it is found that the intelligent inspection of transmission line using UAV for data acquisition and supervision, 5G as transmission channel and digital twin as dynamic simulation tool has the characteristics of immersive monitoring operation, intelligent fault diagnosis, automatic problem tracking and remote centralized control command, which can improve the inspection efficiency of transmission line, dynamic monitoring around substation. The results of fault detection, emergency treatment and self-healing are remarkable. The application of digital twin technology to simulate unmanned unit inspection of transmission lines, substations and key components such as insulators, as well as inspection track and early warning tracking, are more realistic, intelligent, effective and safe, which can improve the overall economic efficiency of power grid transmission supply, operation and maintenance, At the same time, it also improves the intelligent level of power grid and provides a reference for the in-depth research of the technical system.
