Research on Core Algorithms of 3-D Aided UHV Transmission Line Selection Design Platform

UHV power transmission lines are playing very important role in the UHV power system, and the design of transmission line selection is the leading part of the power transmission line project, which is playing a most important role. The rationality of transmission line design impacts cost, difficulty and security of the whole UHV project construction, also impacts overall benefit of power transmission project. Furthermore, it also impacts the whole planning of grid system and country’s security and stability. Along with the development of data gathering technology and hardware of computer, 3-D Aided UHV transmission Line Selection Design Platform (based on 3-D topographic data and 3-D device modeling data,) is already available from both theoretical and technology prospect. And its most key point is the algorithm of 3-D visible Aided transmission Line Selection Design Platform, this paper investigates the algorithm related researches, also includes the technical selection of the algorithm.
