Solar Updraft Tower Power Plant with Thermal Storage

Abstract

A mathematic model is presented for solar updraft tower power plant with water-storage system. This model is developed to evaluate the effect of geometrical parameters of the solar tower power plant and thermal storage system as well as the wind velocity on the power production of the plant. The analysis based on variable solar incident radiation along the day. The results show that the tower tall, the tower diameter, the wind velocity, and the collector diameter have a significant effect on the power production while lhe thickness of the water-storage layer is shifted the peak value of the output power far away from mid-day and more smoothing tha output power curve. The results are compared with other model and experimental data. A good agreement is obtained.
