Intelligent integration has been basically achieved in transmission line design in developed countries, while the current management design level in this field in China is backward and inefficient. According to the characteristics of the pilot transmission line project, it is necessary to build a transmission line 3D design application system based on the grid GIS cloud platform with the advantages of webgl cross platform and without installing plug-ins, to assist in the application of transmission line 3D design, and to develop the interface with professional line 3D design software, so as to realize the smooth operation of GIS elevation and image information and other information such as line selection and capital collection. Experiments prove that the construction of transmission line three-dimensional design application system based on grid GIS cloud platform provides a set of simple, fast, convenient and intelligent and efficient three-dimensional design support for planners and designers. It is an effective means for modern power enterprises to improve management design level and work efficiency, and has great significance in economic and social benefits.

Grid information model (GIM) is a technical standard formulated by State Grid Corporation of China to meet the needs of three-dimensional design of power transmission and transformation projects [1]. According to the characteristics of GIM data, this paper studies the design of distributed computing technology and service architecture to realize the online analysis and optimization of GIM data, so as to improve the efficiency and performance of GIM data analysis. Based on WEBGL technology, with the help of 3D tiles’ LOD ability and the openness of format, a 3D information sharing platform for power transmission and transformation is built to realize the efficient and smooth loading, display and sharing of GIM 3D data on the web.
