【摘要】 应用三维图形技术为变电站仿真系统构造虚拟环境能大大提高变电站场景的真实感,为变电站培训仿真工作带来技术飞跃。文章研究了基于三维图形技术的变电站交互场景仿真的关键技术,给出了基于电气连接特性构造虚拟场景树型层次组织的方法,即“以母线为纬、以单元为经、以断路器为基准,按电气接线顺序排列”;提出了基于特征的实时层次细节模型生成方法和基于虚拟漫游上下文情景的碰撞检测加速算法,并已成功应用于变电站虚拟现实仿真系统中。更多还原

【Abstract】 Constituting virtual-reality environment for substation simulation system by use of three-dimension graphic technology, the sense reality of substation scene can be considerably improved and the simulation and training of substation can be leapt forward technically. The authors research the key technique to simulate the interactive scene of substation based on three-dimension graphic technology, and an organization method to constitute hierarchical tree of virtual substation scene, i.e., taking the busbar and units for the skeleton and the circuit breakers for benchmark, and serially arranging the components according to their connected sequence, is given. A feature based generation method for Level of Detail (LOD) model is put forward and an accelerated algorithm of collision detection based on virtual environment rendering of context scene is proposed. The above-mentioned achievements are successfully applied to virtual-reality simulation system of substation.更多还原
