Abstract
The solar power tower (SPT) is an effective thermal renewable energy source aiming to absorb direct sunbeams on a central collector using thousands of electrical drive-based moved reflectors. The reflector tracking system's accuracy depends on the utilized drive system effectiveness and the used control technique robustness. In this paper, the different electric drives system used in SPT trackers, including motors and power electronic converters, are presented and discussed. Besides, this paper highlighted the advantages and drawbacks of each drive system. Additionally, a dual-axis tracking technique employing the azimuth-elevation tracking approach is discussed and derived for a dual linear actuator heliostat. Moreover, an SPT heliostat prototype using a DC drive system, designed and implemented locally, is discussed and analyzed. The experimental results show the effectiveness of the proposed platform.
