Solar-Tower System With High-Focus-Accuracy Mirror Array |
摘要 |
A solar-tower system includes a raised solar receiver disposed on a tower and a mirror array including multiple flat mirrors for reflecting sunlight onto the raised receiver. The mirror array is disposed on a carousel-type platform that is rotatable around a vertical axis, and the raised receiver is maintained at a substantially fixed position relative to the mirror array for all rotational positions of the platform. A solar azimuth tracking controller controls the platform's rotational position to track the sun's azimuth angle such that sunlight shines on the mirror array from a fixed apparent azimuth angle at all times during daylight hours. Each flat mirror pivots around a corresponding unique axis, and a solar elevation tracking controller individually controls each mirror's pivot position to track the sun's elevation angle such that sunlight is accurately reflected onto the raised solar receiver at all times during daylight hours.
