摘要
虚拟现实技术可以提高变电站仿真培训系统的真实感。研究了变电站仿真培训系统虚拟环境的体系结构,给出了一种基于空间约束和电气特性的虚拟场景组织方法;提出了一种面向实体特性的LOD模型调度方法和基于图象的Impostor模型调度方法;研究了高压放电现象的统计模型,采用粒子系统实现了放电特效仿真。设计实现的变电站虚拟环境成功应用于变电站仿真培训系统。
A virtual environment is helpful for substation training simulator. The architecture of this virtual environment was studied. A new method was applied to organize the devices’ models into a hierarchy tree according to their electric relationship. A Level of Detail algorithm based on objects’ features was used to accelerate the virtual environment rendering. The effects of dielectric breakdown were simulated by particle system using a statistical model. A virtual environment is successfully realized for substation training simulator.
