Development Of Virtual Simulation Experimental Teaching System For Microgrid

With the rapid development of renewable energy,microgrid as a small distributed power system is widely used in China.However,there is a huge gap of professional and technical personnel in microgrid.Traditional microgrid teaching has many problems,such as large area,high cost,low teaching efficiency and certain danger.How to solve these problems and train microgrid professional and technical personnel efficiently has become an urgent need of colleges and universities.Based on 3 ds Max and Unity 3D,this paper proposes a solution based on virtual reality micro-grid experimental teaching system through modular design ideas and demand-oriented thinking.This solution systematically solves the problems existing in the existing traditional microgrid teaching.This article expands on the following areas:(1)Starting from actual needs,using reverse thinking to design specific functions.In the design of the overall architecture,using modular design ideas,a module is an aggregation of similar functions,and the overall architecture of the system is obtained by combining functional modules.(2)Explain in detail the modeling and scene construction process of the micro-grid experimental teaching system.First collect data from microgrid devices and perform proportional modeling.Modeling specifications and techniques are followed during the modeling process.After the model is rendered,import it into Unity 3D and set up the scene.Finally,the second lighting rendering is performed to complete the construction of the experimental scene.(3)Implemented the core module of the system and introduced the key technologies in the system.Developed a teaching and training module with teaching,training and examination as its core functions,relying on rich and real-time feedback and reasonable interaction forms to help users learn.At the same time,the existing collision detection technology is introduced,and the collision detection function of the model is realized in Unity 3D.(4)With Unity 3D as the platform,C#is the development language,which realizes the basic functions of system interaction,event response and scene vision.Finally,the system is tested to ensure that the system can work normally.Based on the above development and research,this paper builds a micro-grid experimental teaching system based on virtual reality technology,which has good immersion and operability,and can be used as an important supplement to the micro-grid training system.
