The Research Of Ultra-high Voltage Three-dimensional Channel Intelligent Management And Control Platform Based On Oblique Photography And Laser Point Cloud Technology

With the continuous advancement and development of the Global Energy Interconnection,the Ultra-high Voltage Power Grid serves as the backbone grid and uses AC and DC hybrid operation to realize a large-scale urban power grid with large-scale input of external power.The UHV AC and DC lines are the "aorta" of power transmission.The importance of safety in operation is self-evident.In order to ensure the safe and reliable operation of the UHV grid,it is necessary to build an intelligent,lean,and high-precision UHV channel visualization platform to continuously improve the level of UHV grid management and control,improve the capacity to redeploy resources,and release the operation and maintenance efficiency.This paper is based on refined three-dimensional modeling,three-dimensional visualization as the information expression method,and the oblique photography and laser point cloud technology as the data support to build a UHV transmission line channel management platform to achieve video,image,micro-meteorology,and tower tilt wait for online monitoring data access,and finally realize the information and visual management of UHV transmission line equipment and channels.On this basis,carrying out online diagnosis and analysis of transmission line and channel status,improving the level of prevention and control of UHV transmission channels and the efficiency of operation and maintenance,finally achieving the 3D intelligent management and control of UHV lines.
