Abstract：Based on mathematical modeling and ray tracing technology,the heliostat field model was established to calculate the optical efficiency and thermal power output of the system,and the application potential of tower solar power generation technology in Lhasa was evaluated.The results show that the output thermal power of the system fluctuates significantly with the seasons.The sunshine time is long in summer and the output thermal power is high,while the total energy output is higher in winter because of the direct use of heat energy.To solve the problem of low cosine efficiency,a method of dividing large mirror into small units is proposed,which effectively improves the optical efficiency.By optimizing the wind resistance performance of the heliostat,it can better adapt to the high altitude and strong wind environment in Lhasa.The research results can provide reference for the popularization and application of tower solar power generation in Lhasa.
