Fast simulation of annual optical efficiency of solar tower power plant

摘要

The simulation of annual optical efficiency is important for the design of a solar tower power plant. The acceleration of the efficiency computation is investigated in this paper. An efficient implementation is presented using a Graphics Processing Unit (GPU) for the optical analysis of the heliostat field in the tower power plant and a new code is developed. The efficiency and the general applicability of the proposed method to different field arrangements are verified by the numerical simulations. The speedup of the calculation on a GPU with respect to that on a CPU is significant.
