In this paper,firstly,the pitch Angle and azimuce Angle of each helostat are determined by solving the azimuce Angle and altitude Angle of the sun,so as to calculate the optical efficiency of the helostat at different times.The projection method to solve the shadow occlusion efficiency,ray tracing method and Monte Carlo algorithm to solve the collector truncation efficiency are mainly elaborated,and then the annual average output thermal power model of the whole helostat field is established.On this basis,by adjusting the position of the absorption tower,the position,number and size of the heliostat and other variables,the annual average thermal power output per unit mirror area is maximized,and a single-objective optimization model is established.Due to the large number of variables,the genetic algorithm is used to initially solve the position of the heliostat,and it is found that the distribution of the heliostat is roughly concentric.Therefore,based on the concentric distribution,the optimal distribution of heliostat field is obtained by using the method of variable step length.
