Among them, the tower solar thermal power generation technology in large-scale solar thermal power generation is the most economic forms of power generation. Due to the related research in the field of solar thermal power generation in China started relatively late, there are a lot of key problems to be solved. I hope this topic by analyzing the movement of the sun law, research the heliostat the condenser tracking control, as far as possible the conditions of the maximum optimized to achieve maximum use of solar energy , so as to promote the development of solar thermal power generation technology, make solar thermal technologies can be more mature and widely used. The concrete content includes: (1) Research of the sun trajectory According to the sun motion model, calculate the altitude Angle and azimuth Angle of the sun, simulate the sun's movement in one day change, and carry out the simulation. (2) Research of the focusing heliostat tracking system According to the Eular rotation matrix, principle of incidence and reflection, the altitude Angle and azimuth Angle of the sun, calculate the altitude Angle and azimuth Angle of the heliostat, and simulate heli
