Method for Determining the Safe Distance of Unmanned Aerial Vehicle Inspection in Centralized Photovoltaic Power Plant by GPS Positioning Technology
Aiming at the problem of the influence of the photovoltaic power plant own electric field on the judgment of the in-spection distance of the unmanned aerial vehicle(UAV)during the UAV inspection,GPS positioning technology is introduced and a method to determine the safe distance of UAV inspection is proposed.GPS positioning technology is used to locate the relevant targets in the process of UAV inspection.The finite element model of photovoltaic power plant was built based on the finite element theory to obtain the initial discharge voltage of the gap between the UAV and the wire and the maximum electric field of the UAV during the gap discharge of the photovoltaic power plant,and the electric field threshold is set.The measure-ment equation of the safe inspection distance was obtained by combining the GPS positioning results and the electric field distri-bution of the power equipment of the photovoltaic power plant,so as to determine the safe inspection distance of the UAV.The experimental results show that the method has high precision and good effect when it is used to determine the safe distance of UAV inspection.
