摘要
变电站巡检能够保证电力系统运行安全,针对目前的变电站巡检路径冲突检测方法存在的误差大、数据延迟时间长等问题,基于数字孪生技术研究了一种新的变电站巡检路径冲突检测方法。采用倾斜摄影技术完成对路径三维数据的采集,采集主要分为影像采集、多视影像平差、多视影像密集匹配。根据采集结果建立矩阵,同时分析平移变换、比例变换、旋转变换的特点,完成路径冲突检测,实现变电站巡检路径优化,完成变电站巡检路径冲突检测。实验结果表明,基于数字孪生技术的变电站巡检路径冲突检测方法的巡检误差小于等于0.5%,延迟时间可控制在0.02ms以内。
Substation patrol inspection can ensure the operation safety of power system.Aiming at the problems of large error and long data delay in the current route conflict detection methods,a new route conflict detection method based on digital twin technology is studied.The oblique photography technology is used to complete the acquisition of the three-dimensional data of the path.The acquisition is mainly divided into image acquisition,multi view image adjustment and multi view image dense matching.The matrix is established according to the collected results,and the characteristics of translation transformation,proportion transformation and rotation transformation are analyzed at the same time to complete the path conflict detection,realize the optimization of substation patrol path,and complete the path conflict detection of substation patrol.The experimental results show that the patrol error of the route conflict detection method based on digital twin technology is less than or equal to 0.5%,and the delay time can be controlled within 0.02 ms.
