文摘

An optical model for a solar power tower with a multi-tube receiver is developed. Solar radiation transfer from heliostat field to receiver is simulated integrally. Visual results of detailed solar flux distribution in the receiver are illustrated. Effects of tracking-error model and aiming strategy are investigated and analyzed. Real-time efficiency is evaluated, and yearly efficiency of 65.9% is revealed.
