Simulation and Experiment of Safety Distance of Substation UAV Inspection

Simulation and experiment of safety distance of substation UAV inspection. With the increasing maturity of UAV technology, the inspection of UAV in transmission lines has been widely carried out at present, but the inspection in substation is still in the initial stage, and the safe flight distance within the station has become the main factor restricting the application of UAV inspection. Therefore, four-rotor longitude and latitude M300RTK model was selected as the research object to build a 3D simulation platform of UAV and 220kV equipment, and to carry out the simulation test of UAV tolerance under electric field and electromagnetic environment of transformer equipment. The simulation results show that when the load current is less than 315A, the critical flight safety distance of UAV is 37cm; when the wire load current is more than 315A, the critical flight safety distance of UAV depends on the safety distance of magnetic field. The research results can provide theoretical reference for UAV substation inspection flight control and inspection path planning.
