摘　　要：利用光线追迹法对定日镜的光学效率进行数学建模,结合放射状栅格法得到定日镜在场中的布局,同时考虑到实际镜场并非已有研究的东西对称型,为此增加吸收塔在东西方向上的位置参数。随后以镜场达到额定年平均输出功率为约束条件、单位镜面面积年平均输出功率最大为目标函数,比较鲸鱼优化、粒子群优化、差分优化对吸收塔位置、定日镜尺寸、定日镜数目、定日镜位置的设计结果经纬(39.4°N,98.5°E)位置,东西对称布局中,鲸鱼优化较另外两种优化,有0.01%~0.05%提升;非东西对称布局中,非对称较对称,有3.6326%提升。The optical efficiency of heliostat is modeled by the ray tracing method in this paper.and the layout of heliostat in the field is obtained by using radial grid method.Considering that the actual mirror field is not an east-west symmetric type,the position parameters of absorber in the east-west direction are added.Then,under the constraint condition that the mirror field reaches the rated annual average output power,and the maximum annual average output power per unit mirror area is the objective function,the design results of whale optimization,particle swarm optimization and differential optimization for the position of the absorber,the size of the heliostat,the number of the heliostat and the position of the heliostat are compared.In the position of longitude and latitude(39.4°N,98.5°E),in the east-west symmetrical layout,the whale optimization has an improvement of 0.01%~0.05%compared with the other two optimization.In the non-east-west symmetrical layout,the asymmetry is more symmetrical,with 3.6326%improvement.
