Research and Implementation of Virtual 3D Scene Modeling Method for Transmission Line

Transmission line stability has great influence on safe operation of the electric power system. The visual management of transmission line can help operators manage and monitor operation status efficiently, which helps to maintain safe and stable operation of transmission line. Virtual 3D scene modeling methods are introduced and evaluated in detail. Based on characteristics analysis, 3D scene of transmission line is designed and implemented. An optimization method based on virtual reality modeling language(VRML) is adopted; experimental results show that the optimization method can reduce data volume considerably. Combined with a third party programming language, the main interface of transmission line visual management system is established. The system has a good application prospect on transmission line safe operation management.
