摘要

工作电压对无人飞行器(UAV)检测和控制的影响主要表现为电磁干扰,其中电场主要影响空间电荷和离子的分布,对无人飞行器产生吸附作用,磁场干扰机载磁力计,破坏无人飞行器的导航系统。在工频条件下,交流电的电磁场呈现交变特性,它只在导线附近极化,形成空间电荷或离子电流,在更远的距离上影响不大。不过,磁场在一个周期内的变化为零(与交流电呈正相关),因此对无人机的影响不是特别大。在直流电条件下,导线中引入恒定电流,导线周围极化的电场会产生恒定性质的电荷或离子电流,因此电场强度相对较大,影响范围也更广。同时,恒定电流产生恒定磁场,施加到机载磁强计上,相当于增加了一个恒定干扰源,从而对无人机的检测和控制产生重大影响。本文使用 ANSYS 软件对不同电压等级的直流输电线路进行电磁场仿真分析。

Analysis of the impact of electromagnetic fields on UAV flight control systems in EHV–UHV DC overhead transmission lines
The impact of operating voltage on Unmanned Aerial Vehicle (UAV) inspection and control is mainly manifested as electromagnetic interference, where the electric field mainly affects the distribution of space charges and ions, exhibiting adsorption effects on UAVs, and the magnetic field interferes with airborne magnetometers, disrupting the navigation system of UAVs. Under power frequency conditions, the electromagnetic field of alternating current exhibits alternating characteristics, and it only polarizes near the wire to form space charges or ion currents, with little effect at further distances. However, the variation in the magnetic field in one cycle is zero (positively correlated with alternating current), so its impact on UAVs is not particularly significant. Under direct current conditions, a constant current is introduced into the wire, and the electric field polarized around the wire generates a constant property of charge or ion current, resulting in a relatively larger electric field strength and a wider range of influence. At the same time, the constant current generates a constant magnetic field, which is applied to the airborne magnetometer, equivalent to adding a constant interference source, thus having a significant impact on the inspection and control of UAVs. This article uses ANSYS software to conduct electromagnetic field simulation analysis on DC transmission lines of different voltage levels.

期刊介绍: AIP Advances is an open access journal publishing in all areas of physical sciences—applied, theoretical, and experimental. All published articles are freely available to read, download, and share. The journal prides itself on the belief that all good science is important and relevant. Our inclusive scope and publication standards make it an essential outlet for scientists in the physical sciences. AIP Advances is a community-based journal, with a fast production cycle. The quick publication process and open-access model allows us to quickly distribute new scientific concepts. Our Editors, assisted by peer review, determine whether a manuscript is technically correct and original. After publication, the readership evaluates whether a manuscript is timely, relevant, or significant.
