摘要
提出了一种动态模拟太阳能塔式热发电聚光场焦斑及焦面上能流密度分布的方法,采用光线追迹法对聚光过程进行建模,推导了焦斑计算公式,并编制了基于MATLAB的应用程序,实现了对焦斑及焦面上能流密度分布的实时模拟,给出了焦斑分布及焦面上任意点能流密度随时间的变化曲线.
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.
