Optimal Heliostat System Using Hybrid Type Solar Tracking Device

The purpose of this research is to develop the algorithms that control the behavior of heliostat in real time. Tracking the sun and calculating the position of the sun are possible by using illuminance sensor (CdS). As heat transfer from heliostat to receiver is delivered by solar radiation, configuration factor commonly utilized in radiation is applied to control heliostat. Algorithms for maximizing configuration factor between heliostat to receiver in real time are programmed by Simulink. By applying the optimized algorithms, the efficiency of the solar absorption in receiver can be maximized. Simulation was performed how to change the incidence angle during the daytime with respect to diverse distances.
