塔式光热电镜场布置方案的研究

Theoretical Study on the Arrangement Scheme of Tower Photothermal Electron Microscope Field

主要是通过MATLAB进行仿真研究,来为塔式光热电站镜场的布置提供一个参考方案。塔式光热电镜场的布置主要受到以下几种因素的影响:余弦损失、大气衰减损失、中心点距离效率、遮挡损失、地理纬度等。将余弦效率、大气衰减损失、中心点距离效率的乘积定义为镜场光学利用效率,用做镜场布置的参考。研究主要考虑纬度对镜场布置的影响,通过绘制纬度为15°、30°和40°的塔式光热电站镜场,从而对不同纬度下镜场布置做出分析。理论分析的结果表明:纬度越低,镜场达到相同功率输出时所需要的定日镜数量越少;反之纬度越高,镜场达到相同功率输出所需要的定日镜数量越多。

Mainly carries on the simulation research through Matlab,to provide a reference scheme for the arrangement of the mirror field of the tower-type photothermal power station.The arrangement of the tower photothermal electron microscope field is mainly affected by the following factors:cosine loss,atmospheric attenuation loss,center distance efficiency,shielding loss,geographical latitude and so on.The product of cosine efficiency,atmospheric attenuation loss and distance efficiency of center point is defined as the optical utilization efficiency of mirror field.In this study,the influence of latitude on the layout of the mirror field is considered,and the layout of the mirror field of the tower photothermal power station with latitude of 15,30 and 40 is analyzed.The theoretical analysis shows that the lower the latitude,the less the number of heliostats needed to achieve the same power output.Conversely,the higher the latitude,the more the heliostats needed to achieve the same power output.
