摘要
为了避免无人机上电子元器件在正常作业过程中受强电场影响,获得更好的输电线路运行状态信息反馈,以500 kV双回交流输电线路为原型,分析探究无人机巡检时的安全路径方案。通过Ansys软件建立仿真模型,利用有限元分析法对高压输电线路周围电场进行求解,得出无人机巡检飞行的安全范围。采用最小二乘法对仿真得到的安全范围边界分段进行函数拟合,并得到描述无人机巡检时安全边界的函数拟合数学模型。结合无人机巡检时理想观测角度的相关信息,利用函数拟合数学模型,计算出巡检对象所对应的各个理想观测端点及其范围。所提出的无人机高压输电线路巡检安全路径方案,有利于提升无人机作业时的安全性和高效性。
To avoid the influence of strong electric fields on electronic components on unmanned aerial vehicle(UAV)during normal operation and obtain better feedback on the operation status of transmission lines,a safety pathway for UAV inspection is analyzed by using a 500 kV double circuit AC transmission line as an example Ansys software is used to establish a simulation model and finite element analysis method is used to solve the electric field around high-voltage transmission lines so that the safe range of UAV inspection flight is obtained.The least squares method is used to segment the safety range boundary obtained from simulation and a function fitting mathematical model that describes the safety boundary during UAV inspection is obtained.Based on the relevant information of ideal observation angle during UAV inspection and the function fitting of the mathematical model,the ideal observation endpoints and their ranges corresponding to the inspection object are calculated.The proposed high-voltage transmission line safety pathway scheme for UAV inspection is beneficial for improving the safety and efficiency of UAV operation.
