Abstract: By using the virtual simulation technology and taking the generation, utilization and optimization process of hydroelectric power as the frame, a comprehensive and overall experimental teaching system for the whole process of hydroelectric power generation with the whole basin, large scene and multiple levels is established. This system consists of two modules: hydroelectric power science, water resources and water information. By building a digital model of the entire process of hydroelectric power generation, students can systematically master basic professional knowledge. By optimizing the experimental teaching system, students’ innovative thinking ability and professional practice ability are cultivated.
