摘要
高压输电线路周围恶劣的电磁环境会直接影响巡检无人机运行的稳定性,进而影响地面操作人员对巡检结果的评估。为保障巡检无人机在恶劣电磁环境下巡检作业的可靠性,对无人机巡检作业的电磁环境进行仿真。根据干扰电磁波的耦合途径分别构造电场耦合模型与磁场耦合模型,对无人机内部电气结构与高压输电线路之间的耦合进行分析从而确定受扰对象,从干扰源的产生及电磁耦合途径出发,对无人机进行电磁兼容优化,利用电磁屏蔽削弱无人机内部电气结构及敏感元件所受到的电磁干扰,使无人机的电磁兼容性能得到提升,保障巡检无人机运行的稳定性。
The complex electromagnetic environment around the high-voltage transmission line affects the steady operation of the patrol UAV directly,and further affects the evaluation results of the patrol inspection by ground operators.In order to ensure the reliability of UAV in the harsh electromagnetic environment,the electromagnetic environment around UAV is simulated.Based on the coupling path of interference electromagnetic wave,the electric field coupling model and the magnetic field coupling model are constructed respectively.The coupling between the internal electrical structure of UAV and the high-voltage transmission line is analyzed to determine the disturbed target.Based on the generation of the interference source and the electromagnetic coupling path,the electromagnetic compatibility optimization of the UAV is carried out.The electromagnetic shielding is used to weaken the electromagnetic interference to the internal electrical structure and sensitive components of the UAV,so that the electromagnetic compatibility performance of the UAV is improved,and the operation stability of the patrol UAV is guaranteed.
