Research on Electromagnetic Simulation and Safety Distance of UAV in Substation Based on Finite Element Simulation

In order to reduce the electromagnetic interference caused by unmanned aerial vehicle (UAV) inspections on the busbars in substations, a finite element simulation based electromagnetic simulation calculation method for UAV surroundings in substations is proposed. Based on the finite element simulation software, a simulation model for the electric and magnetic fields of the busbars in the substation is established, and it obtain the distribution of electric and magnetic fields along different paths around the busbars in the substation; On this basis, According to the structural parameters of the UAV, a three-dimensional simulation model of the UAV is established to analyze the distribution characteristics of electric and magnetic fields around. Based on the allowable limits of electric and magnetic fields around the UAV, determine the safe distance of the UAV around the busbar in the substation, significantly improving the safety and stability of UAV inspections.
