【摘要】 可视化仿真技术是近些年来发展起来的计算机应用技术，在诸如汽车、航天等领域均有广泛的应用。在水利系统中，也有一些专家学者开始了可视化仿真系统应用的研究。本文正是在这样的背景下，对水电站输水系统的水力过渡过程的可视化仿真系统进行了研究。 首先，本文介绍可视化仿真系统设计中的相关设计技术，包括可视化技术、计算机仿真技术、组件化程序设计技术以及数据库技术等等。 其次，本文重点阐述了应用OpenGL三维图形标准进行通用模型构建模块的分析设计，并给出了由本系统绘制的真实水电站输水系统的整体水工模型图。在整体模型构建的基础上，根据试验数据和计算数据，实现了输水系统中流体瞬变物理量的动态的演示。 最后，本文应用了水电站中非恒定流的计算方法，给出了一个系统实现的实例。结果表明，本系统能正确有效地解决实际的工程问题，具有较大的实用价值。更多还原

【Abstract】 The simulation technology of visualization is a new computer application technology which has developed in recent years. In the fields such as mobile, aircraft ,etc, it is used widely. Some experts and scholars started to research the application of visualization simulation system in the water resources field. In such a background, this paper investigated the visualization simulation system which is applied to simulate the transient process of the water conveyance system in the hydropower station.First, the technology of the visualization simulation system, including the visualization technology, computer simulation technology, component programming technology and database technology, are introduced.Second, this paper expounded the analysis of the universal model by means of the OpenGL 3D graphics standard. The whole model of a real hydropower station was also provided by this system. On the base of the whole model structure, it realized the dynamic display of the transient fluid parameters in the conduit according to data available.Finally, this paper applies the computational method of the unsteady flow in the hydropower station and a simulation case was given. The results show that the engineering problems can be solved effectively by this system.更多还原
