摘要
三维虚拟场景下的电力大数据全景可视化以场景物体灵活多样的显示状态对深层电力特征信息进行直观呈现,以场景漫游的形式对海量多态、异构数据进行全景实时展现,为电网运行状态的及时有效监控分析提供有力保障。针对其场景管理问题,提出了基于空间分割的电力大数据三维全景可视化场景管理方法。首先,构建空间分割代价函数并产生分割平面选择因子,优化场景空间分割。然后,根据场景空间分割结果,建立电力大数据场景组织关联模型,一体化组织管理场景物体、环境和实时分析数据,并实现物体显示状态实时控制及场景漫游快速渲染。最后,通过变电站数据三维全景可视化分析系统的场景管理应用,验证了该方法的有效性。
The power big data panoramic visualization based on three-dimensional virtual scene presents the deep infor- mation with electric power feature intuitively with the flexible display status of the scene object, executes the real-time panoramic presentation of massive, multi-state and heterogeneous data which are raised from the electric power big data visualization with the form of scene roaming, and provides strong guarantee to the supervision and control analysis to the operating status of the power grid. The paper aims at its scene management problems, and the scene management method of electric power big data three-dimensional panoramic visualization is proposed based on space partition. First, on the basis of the scene partition analysis, the cost function of the scene space partition is constructed and the split plane selec- tion factor is selected. The traditional space partition is optimized. The objects, the environment and the real-time analy- sis data are organized with the form of the electric power big data panoramic organizational relation model which is based on the scene partition result. The real-time control of the objects display status in the scene and the quick rendering of the scene roaming are realized. Finally, the effectiveness of the method is verified by applying the method to the scene man- agement in the three-dimensional panoramic visualized analysis system of the substation data.
