[Abstract]:Solar energy is a kind of renewable clean energy. How to apply solar energy to solve the problem of energy and pollution is an important research direction at present. As an ideal large-scale power generation method, tower solar thermal power generation technology has a broad application prospect. The design of focusing mirror field is the core of power station design, but there are some imperfections in the design method of focusing mirror field. At the same time, 3D visual simulation technology is becoming more and more mature, and its application is extended from the initial field of military industry to many fields such as industrial design, medical treatment, teaching and so on, and promotes the development of corresponding fields. In this paper, the design method of focusing mirror field and the focusing process of solar mirror in tower solar thermal power station are studied and analyzed, and combined with the advantages and characteristics of 3D visual simulation technology, Pro/E,MultiGen Creator, is applied. The visual scene simulation system of visual concentrator based on MFC is established by Vega Prime and Visual Studio software. The main results of this paper are as follows: 1. Based on the investigation of domestic and foreign literatures, the field arrangement method of radiative grid focusing mirror based on radiative grid method is put forward. On this basis, the mathematical model of the position coordinate of helioscope is established, and a perfect design method of concentrator field is formed. This arrangement method is more effective to avoid large optical loss. 2. Based on the analysis of the solar trajectory, a solar motion model with the solar altitude angle and azimuth as the index is established and the effectiveness of the algorithm is verified. The operation mode of the helioscope and the reflection principle of solar light are further analyzed. On the basis of the solar motion model, a solar tracking model is established, which takes the height angle and azimuth angle of the fixed helioscope as the index. Taking the rated power as the 70KW power station as the simulation object, the simulation model is established by Pro/E, and the model simplification, configuration and drive of the simulation system are completed by Creator/Vega Prime, and the visual scene simulation effect is realized. 4. Taking Visual Studio as the development platform, through the mixed programming of Vega Prime and OpenGL, a visual simulation system is developed, which can reproduce the daily pursuit process of the focusing mirror field. There are rich menu functions in the interactive interface, the shortcut key operation mode should be set, and the simulation scene real-time information display window is added to display the simulation scene running parameters in real-time. The visual simulation system has perfect function, friendly interactive interface and simple operation, and has achieved ideal results. In practical use, the system can not only be used in focused mirror field design, to help users quickly and intuitively obtain the sun and helioscope-related parameter information, but also can be used in teaching or demonstration. To help observers intuitively understand the working principle of tower solar thermal power station and the sunpursuit process of focusing mirror field.
