This paper conducts an in-depth study on the layout optimization of heliostat fields in solar thermal power generation systems. Initially, by analyzing the impact of heliostat size and quantity on power generation efficiency, an optimization model targeting the enhancement of thermal efficiency is established. This model comprehensively considers multiple factors including beam density, atmospheric transmissivity, shadow and blockage efficiency, cosine efficiency, and truncation efficiency. The study demonstrates that effectively adjusting the angle and position of each mirror significantly improves the system's thermal efficiency. In the optimized layout scheme, a total of 5,209 heliostats, each measuring 4m x 4m, are arranged around a central absorber tower 80 meters high. The optimization results indicate significant improvements in various efficiency aspects, with the system's average annual output thermal power reaching 60.597 MW, and the average output thermal power per square meter of mirror surface being 0.692 kW/m². Finally, this research not only proposes a beneficial framework for solar field layout optimization but also recommends further experimental validation and numerical simulation for better practical application.
