Design and development of virtual planning system for urban underground power pipelines

The layout of underground transmission lines involves problems like various considerations, complex restrictions, and intensive integrated system information. This article discusses how the 3D virtual layout can be used in underground transmission lines and other applications, based on the technologies and theories of the underground transmission lines. 3D virtual transmission line system will be widely used in large hydro transmission systems because of its advantages, and the research of the algorithm optimization on real-time rendering, planning methods customizing by planner client and issued based on Web server and B/S structure will be deepened.
