Abstract
The digitization of power grid projects is a development requirement in the era of big data, as well as an inevitable requirement for the State Grid Corporation of China to build digital power grids and improve life-cycle management. Three-dimensional design establishes three-dimensional models of ground conductors, insulators, and fittings through line electrical majors, and completes line poles and towers in a three-dimensional scene; line structure majors should establish iron tower models and basic models; survey majors should conduct topography and landforms and ground objects to complete three-dimensional scene construction. It can make the circuit design results more intuitive, reduce the drawing work of repeated components, and improve the design efficiency.
Highlights
Digital technology is gradually integrated into the power grid design industry, and interactive collaborative design and three-dimensional design promote the continuous development of information technology for power grid survey and design
The application of three-dimensional digital technology to the design of transmission line engineering has become a hot topic of current research[1]
The archiving of three-dimensional design documents mainly adopts the method of outputting two-dimensional graphics for archiving, and some companies engrave the final version of electronic files into CD-ROM for archiving
Summary
Digital technology is gradually integrated into the power grid design industry, and interactive collaborative design and three-dimensional design promote the continuous development of information technology for power grid survey and design. The case is based on the database, based on high-precision image data, and based on the parameterized transmission line model to achieve collaborative operation, and deep integration of surveying and mapping practice and design, effectively improving design efficiency[5]. 1.5 Route selection In the three-dimensional design of power transmission engineering, a full three-dimensional path design must be realized. 1.6 The tower spotting in transmission line The towers arrangement of transmission lines is based on route selection, and arranging towers and related verifications on the existing optimal path. It can realize the functions of three-dimensional line roaming and ranking check
