Modeling and simulation of heliostats field in solar power tower

With the widespread use and preliminary mature of solar energy generation technology, the improvement of generating efficiency has become a vital technical target. For the tower-solar thermal generation system, the design and optimization of the heliostats field is of great significance for improving generating efficiency, rationalizing the energy dispatching and seizing the distribution and variation trend of the whole power plant. Firstly, in this paper, an energy model of the tower-solar thermal generation system is established and the parameters are analyzed. Then, the reflection model of a single heliostat is established and the mechanical characteristics and cosine effect are analyzed. Finally, the energy distribution and scheduling solution are obtained. Proved by simulation, analysis based on this model has certain guiding significance on actual production.
