Design And Research Of Multi-glasses Concentration And Tracking Photovoltaic System

Solar using is an important research field of energy using. one of the important research problems.is to improve the electeicial efficiency of solar cell. In this paper, a Multi-glasses Concentration and Tracking Photovoltaic System is designed. .based on multi-glasses refracted concentration. According to the effective refraction angle information provided by panorama picture which content information of angle and character of sun area, the floating sun position can be real-time tracked and locatied.The main work of this paper:1,the concentration mode of photovoltaic system is analysised. An overall arrangement and moving equation and correspind control method of plane glasses is presented in multi-glasses refracted concentration mode2,According to the information of angle in panorama picture, a solar locating and tracking method is presented the sun area in sky panorama picture is recognized by the method of object character knowledge. The humanoid vision brightness sensitivity is simulated. The high bright area is emphasized in the panorama picture by (H, S, I) math transform domain algorithm. Sun area is recognized by using dynamic characters such as outline, offset and proportion of area. The azimuth angle and the vertical angle between the vision point and the sun spot are calculated.3,A Multi-glasses Concentration and Tracking Photovoltaic System is designed. The system structure and hardware principle chart and software flow chart is presented. The result of the experimentation shows that this method is useful and valuable.The data is provided by five glasses concentration and tracking experiment system. It can be concluded by analysising these data that this method is not only very nicety in nice day, but also useful in bad situation such as be sheltered from object, ray diffusion or picture distortion. The electeicial efficiency of solar cell can be enhanced to 3-4 times.
