This research explores the application of Unmanned Aerial Vehicles (UAV) technology in the restoration of electricity in residential areas. We begin by posing the research question: how to enhance the efficiency and accuracy of emergency repairs in power systems. Next, the method involving the use of UAVs for fault detection and data transmission is introduced, with a special emphasis on the roles of 5G communication and deep learning technologies. The effectiveness of this approach is validated through experiments and data analysis. Finally, we conclude that UAV technology significantly improves the response speed and accuracy of emergency repairs in power systems, showcasing its potential in future power system management.
