Analysis on Optical Performance of the Concentrator Field in the Solar Tower Thermal Power System
太阳能塔式热发电聚光场的光学性能分析

A method was proposed for simulating the focal plot of the concentrator field and the energy flow on the focal plane dynamically in the solar tower thermal power system.The numerical model of the concentrator field was made by ray-tracing.The theory of calculation of the focal plot was derived.A procedure based on MATLAB was developed for carrying out the real-time simulation of the focal plot and the energy flow.By using this procedure,the focal plot of the concentrator field at various instant of time can be given and the distribution of the energy flow as function of time on various position of the focal plane can be drawn.
