A tower-type solar power station comprised of heliostats and a collector stands as a pivotal solution for harnessing solar energy and transforming it into thermal energy, facilitating clean energy production. In the preliminary stages of constructing tower solar thermal power stations, optimizing the layout of heliostat fields emerges as a critical concern. This paper delves into the investigation of various parameters such as annual average optical efficiency, annual average thermal output, and annual average thermal output per unit mirror area of the heliostat field. Through the establishment of a mirror coordinate system, cosine efficiency model, atmospheric attenuation model, and truncation efficiency model based on predefined heliostat dimensions and positions, we meticulously calculate shadow shading efficiency, cosine efficiency, atmospheric attenuation efficiency, and truncation efficiency of the heliostat field. These analyses contribute significantly to the design and optimization of heliostat fields, enhancing the overall performance and efficiency of tower-type solar power stations.
