无人机航测数据在架空输电线路三维设计中的应用

Application of UAV Aerial Survey Data in Three-Dimensional Design of Overhead Transmission Lines

目前国家电网有限公司大力推行输变电工程三维设计,而三维设计需要以高精度航测数据、电网专题数据、工程勘测数据等作为基础数据[1]。通过分析无人机航测数据误差来源,分别选取山区和平原地区作为实验区,利用航测数据与实测数据进行对比分析,结果表明在平原地区利用无人机航测数据能够满足架空输电线路三维设计要求。结合安徽阜南—董庄220 kV输电线路工程,从选线及路径优化、绘制初步平断面图以及前期工程量估算3个方面,具体阐述无人机航测数据在架空输电线路三维设计中的应用,提高输电线路工程设计质量与效率。

At present,State Grid Co.,Ltd.vigorously promotes three-dimensional design of power transmission and transformation projects,and the three-dimensional design needs high-precision aerial survey data,power grid thematic data,engineering survey data as the basic data.In this paper,by analyzing the error sources of UAV aerial survey data,mountain area and plain area are selected as experimental areas,and the results show that the use of UAV aerial survey data in plain area can meet the three-dimensional design requirements of overhead transmission lines.Combined with the 220 kV transmission line project from Funan to Dongzhuang in Anhui Province,the application of UAV aerial survey data in the three-dimensional design of overhead transmission lines is elaborated from three aspects:line selection and route optimization,drawing preliminary plane section diagram and preliminary engineering volume estimation,which greatly improves the quality and efficiency of transmission line engineering design.
