摘要:
为了实现利用输电线路空间电场分布特征的无人机巡检智能导航避障,研究交叉跨越区域 空间电场强度分布规律,利用三维电场估算法和 Ansys 有限元分析软件,对交流 500 kV 垂直跨越 220 kV 线路进行三维建模计算。结果表明,在与交叉区域水平距离保持不变的情况下,随着测试
点高度的变化,电场强度呈现先增大后减少的变化规律; 此外,高电压等级线路对交叉区域电场强度分布起主导作用。此外,在保持测试点高度不变的情况下,随着测试点与交叉区域距离的增大,电场强度值呈现明显的单调递减变化趋势。利用小型无人机搭载电场测试仪对交叉区域电场实测,实测值和理论值误差均在允许范围内,证明了分析结果的有效性,所研究对输电工程的空间电磁分析提供参考意义。
Abstract:
In order to realize the intelligent navigation and obstacle avoidance of unmanned aerial vehicles ( UAV) ,the distribution characteristics of spatial electric field intensity are studied in the paper.A threedimensional calculation model of AC 500 kV vertical crossing 220 kV transmission line was established to study the electric field intensity distribution in the paper by using the estimation method of three-dimensional electric field and the finite element analysis software ( Ansys) . The results show that the electric field intensity rises at first and then goes down with the change of the test point height in the case of keeping the horizontal distance.The higher voltage level line plays a leading role in the crossing area.In addition,the electric field intensity is obviously decreased along with the increase of the distance between the test point and the crossing area in the case of keeping the height of test point.In this paper,a small multi rotor UAV equipped with test equipment is used to measure the electric field in the crossing area.The result shows that the error value is within the allowable range,which proves the validity of the analytic results.The research of this paper provides reference value for the analysis of space electromagnetic field.
