基于电磁场信息的输电线路无人机巡检安全距离仿真分析

Simulation Analysis and Research on Safety Distance of Unmanned Aerial Vehicle Patrol for Transmission Line Based on Electromagnetic Field Information

随着电网规模和新型技术的不断发展,输电线路的运维工作正由传统巡检模式逐步跨入智能化巡检阶段。无人机作为一种高效便携稳定的巡检设备目前正被广泛应用于输电线路的日常巡检工作中。巡检过程中高压带电导线产生的电磁场环境会对无人机的正常巡检造成干扰,同时无人机的抵近飞行会引起带电导体周边电磁场的畸变。文章通过建立交流架空线路模型,以电力行业广泛应用的某Ⅲ类四旋翼无人机为例,分析其离带电导线不同距离下表面承受的电磁场信息,基于仿真数据提出无人机巡检的安全距离。

With the continuous development of power grid scale and new technology,the operation and maintenance of transmission lines is gradually moving from the traditional inspection mode into the intelligent inspection stage.As a highly efficient,portable and stable inspection equipment,unmanned aerial vehicle(uav)is widely used in the inspection of power transmission lines.In the process of inspection,the electromagnetic field surrounding the high-voltage live conductor will cause interference to the normal inspection of the uav.At the same time,the proximity flight of the uav will cause the electromagnetic field distortion around the live conductor.In this paper,by establishing the model of communication overhead conductors,with aⅢ-type four-rotor unmanned aerial vehicle,widely used in electric power industry,as an example,analyzes the electromagnetic field information on its surface with different distance from the charged conductor and presents the safe distance of unmanned aerial vehicle(uav)inspection based on the simulation data.
