随着无人机以及各种控制技术的发展,无人机巡检技术被广泛地应用于电网。目前,无人机在电磁场环境下的避障还存在一些缺陷。为了探讨无人机在巡检时,现场运行输电线路对无人机表面电场的影响,文中通过SolidWorks建立了铁塔、导线、大疆M300RTK无人机、电场传感器等设备的模型,导入有限元仿真计算软件Ansoft Maxwell中开展了整体的电场计算。通过改变电压角度获得了一个最合适电压值作为静电场仿真的运行输电线路设置电压,仿真研究了不同距离条件下,无人机、机翼、传感器位置等对无人机表面电场的影响。获得了不同条件下输电线路对无人机表面场强的影响,仿真研究结果可为现场无人机的巡检策略提供数据参考和理论依据。

With the development of unmanned aerial vehicle(UAV)and various control technologies,UAV patrol technology is widely used in the power grid.At present,there are still some shortcomings in the obstacle avoidance of UAV operating in electromagnetic field environment.For studying the influence of the operating transmission line on the surface electric field strength of UAV during patrol inspection,the models of tower,wire,DJI M300RTK UAV,electric field sensor are set up by SolidWorks software,then imported into the finite element simulation calculation software Ansoft Maxwell to perform overall electric filed calculation.One most suitable voltage is obtained by chang⁃ing the voltage angle as the power transmission line setting voltage of electrostatic field simulation.And the influence on surface electric field of the UAV from such positions as UAV shape,wing,sensor location is simulated and studied in different distance conditions.The influence of power transmission line on UAV surface field strength under differ⁃ent conditions is obtained by simulation and the research results in this paper can provide data reference and theoreti⁃cal basis for the patrol strategy of UAV at site.
