摘要
无人机架空线路巡检技术已在电力系统中得到广泛应用,但目前无人机与导线的距离主要依靠肉眼判断,缺乏有效的测距技术。基于有限元算法及ANSYS软件建立了特高压架空线路的电磁仿真模型,分析计算了不同电磁场分量与导线距离的关系,提出了选用电场有效值结合高度的方法来确定无人机与输电线路真实距离的方法。该方法可为输电线路无人机巡检距离检测、航向规划、避障设计提供参考。
UAV overhead lines patrol technology has been widely used in power system. However, the distance detection between UAV and lines mainly depends on human eyes. Based on the finite element method and ANSYS software, the electromagnetic simulation model of UHV overhead lines is established in this paper, and the relationship between the electromagnetic field component and overhead line distance is analyzed. Finally, a method based on the effective value of electric field and UAV altitude to detect the distance between UAV and overhead line is proposed. This method provides a basis for patrol distance detection, route planning and obstacle avoidance design for UAV inspection of overhead lines.
