【Abstract】 With the advances in information technology, three-dimensional visualization technology is developing rapidly in various fields, playing an increasingly large role. Three-dimensional visualization technology gradually penetrates into the power sector, and has a widespread application,which has become a phenomenon can not be ignored. Thus,it has great significance that depth study the application innovation of three-dimensional visualization technology in power sector. Paper combined Shandong Province Science and Technology Development Project "Key Technology Research and realization of flexible manufacturing design CAD system," studied the application of three-dimensional visualization in the power line sitting and optimization. The paper made the following research and innovation.1、Through the analysis of three-dimensional visualization technology, the paper proposed to combine it with Google Earth, applied to the power line selection optimization jointly.2、Designed a three-dimensional CAD system of Site selection and optimization of the power line for the power industry, used C ++ as the programming language, mainly studied the system application tools layer, designed and implemented the geometry engine of power line sitting and optimization.3、 Through Google Earth secondary development, solved the data sources in the simulation of three-dimensional terrain and the power line. At the same time, by coordinate transformation, improved the availability of data.4、Used ACIS/HOOPS to be modeling and simulation platform for terrain and power lines and other display.5、In this paper, the main innovation is that the introduction of Dijkstra algorithm and evolutionary algorithm, the original power lines were optimized and implemented the real-time dynamic adjustment and optimization on 3D simulation terrain. At the same time, by generating KML file, returned optimized power lines on Google Earth to display.更多还原
