摘要
为提高塔式太阳能的辐射反射效率和发电性能,需要对定日镜场进行布局优化。采用日平均年光学效率的方法,计算分析定日镜年均余弦效率、大气衰减效率、截断效率及最大光学效率,为后续定日镜场的布置及优化提供评价指标。以西班牙Gemasolar塔式电站为例,采用密集campo的布置方法进行镜场初始化,验证了布置方法的高光学效率和高可靠性。采用差分进化算法对镜场进行优化,镜场年均综合效率由56.99%提高至59.03%,提升了3.58%,验证了该方法的有效性。
In order to improve the radiation reflection efficiency and power generation performance of tower solar energy,it is necessary to optimize the layout of the heliostat field.Using the method of daily average optical efficiency,the average cosine efficiency,atmospheric attenuation efficiency,truncation efficiency,and maximum optical efficiency were calculated and analyzed,providing evaluation indicators for the subsequent arrangement and optimization of heliostat fields.Taking the Gemasolar tower power plant in Spain as an example,the optical efficiency and reliability of the arrangement method were verified to be high by using a dense campo arranged mirror field as the initial mirror field.Using Differential Evolution to optimize the mirror field,the annual average comprehensive efficiency of the mirror field increased from 56.99%to 59.03%,an increase of 3.58%,which proved the effectiveness of the method.
