【Abstract】 In this study, a new generation method of the solar power tower heliostat field is proposed and used to improve the layout of the Solar Two plant heliostat field. First, the new heliostat field layout parameters were optimized by the genetic algorithm with the annual weighted optical efficiency as the objective function. Then, the optical-thermal comprehensive performance indexs for the concentrating and collecting sbusystem under the initial heliostat field of the Solar Two plant and the optimized new heliostat field were compared. The results reveal that the optical efficiency and the solar flux distribution uniformity index of the optimized new heliostat field show certain advantages. In terms of the fluid flow and heat transfer performance, it is found that the new heliostat field has a certain effect on the improvement of the thermal efficiency of the receiver, the annual average thermal efficiency of the receiver is increased by 1.65% under the new heliostat field.The new heliostat field layout generated by the proposed new heliostat field generation method can effectively improve the optical-thermal comprehensive performance of the solar power tower plant,which could provide a reference for the design of concentrating and collecting subsystem of solar power towers.更多还原
