虚拟仿真系统在水电站教学中的应用研究

Application of virtual simulation system in the hydropower station teaching

随着计算机技术的发展,采用虚拟现实技术可将具有时空特性的水利水电工程数据集合进行可视化分析。将虚拟现实技术运用到水电站教学中,建立河床式水电站的仿真试验模型。学生在虚拟仿真实验过程中,可深入了解电站枢纽、电站厂房、轴流式水轮机等水利水电工程和设备,并能模拟水轮机组安装与检修。在开放式实验教学环境中,要求学生自主构想、设计、完成并验证虚拟模型,教学效果显著。在理论结合虚拟仿真的指导下,使学生提高认识,增强能力,充分体现CDIO工程教育模式的优势。

With the development of computers,the visualization analysis can be conducted by the virtual reality technology of hydropower project engineering data set that has spatiotemporal characteristics. To apply this technology to the hydropower station teaching,a virtual simulation of power station in river channel can be established. Through the virtual simulation of hydropower engineering and equipment such as the hydro-junction,power plant and axial flow turbine,and the virtual simulation of the installation and maintenance of hydraulic turbine,the water resources and hydropower engineering simulation experiment was realized. In the teaching mode of open experiment,students were the main body and they were required to independently compose,design,finish and verify the virtual model. The teaching effect was remarkable and the new concept of engineering education can be implemented. The guidance of theory combined with the virtual simulation improved students＇ understanding and enhanced their practical ability,which realized the goal of CDIO engineering education mode.
