Power Transmission Scene Simulation in a Large Scale Terrain Environment

To facilitate management of power transmission system, a simulation to power transmission system is needed. We design and implement a 3D power transmission scene simulation system based on 3D graphics engine. The system is a distributed scene rendering system, it supports multi-channel rendering. To simulate power transmission scene, at first, various 3D models including substations, towers, buildings etc are created. To render power transmission scene under a large scale terrain environment, a large scale multi-level LOD terrain database is built based on DTED and relevant image data. To realize a matching of ground objects with the terrain surface, several ground clamping methods are used. The system can be used in power transmission system management, power transmission line design and training simulation fields.
