为解决传统三维超高压输电站架空线路智能布设误差高的问题,基于地物属性识别技术设计三维超高压输电站架空线路智能布设方法,即建立三维超高压输电站架空线路地物属性识别矩阵,在地物属性识别技术处理局部特征描述子的基础上,划分三维超高压输电站架空线路智能布设点间距,修正架空线路智能布设位置,并设计架空线路智能布设细部,完成三维超高压输电站架空线路智能布设。实例分析结果表明,设计方法布设误差远低于对照组,能解决传统布设误差高的问题。

In order to solve the problem of high error in intelligent layout of overhead lines in traditional three-dimensional EHV power transmission station,based on the ground feature recognition technology,the intelligent layout method of 3D EHV transmission station overhead lines is designed.That is to say,the ground attribute recognition matrix of 3D EHV transmission power station overhead lines is established.Based on the local feature descriptors processed by the ground attribute recognition technology,the distance between intelligent layout points of 3D EHV transmission power station overhead lines is divided,and the intelligent layout position of overhead lines is corrected.The details of the intelligent layout of overhead lines are designed to complete the intelligent layout of overhead lines in three-dimensional EHV power transmission station.The results of the case analysis show that the layout error of the design method is far lower than that of the control group,which can solve the problem of high traditional layout error.
