在国内建立了太阳能烟囱热电发电的中试试验装置。在建立数学模型的基础上，对该发电系统的性能进行了仿真研究。得到了不同太阳总辐射强度、集热器面积和烟囱高度下的稳态模拟输出功率。通过对比发现，模拟输出功率与实测计算结果基本吻合，验证了太阳能烟囱热发电系统的数学模型。此外，根据模拟和特定场地的特定建筑成本，可以选择烟囱和集热器尺寸的最佳组合，以满足所需的电力输出。
A pilot experimental solar chimney thermal power generating equipment was set up in China. A simulation study was carried out to investigate the performance of the power generating system based on a developed mathematical model. The simulated power outputs in steady state were obtained for different global solar radiation intensity, collector area and chimney height. By intercomparison, it is found that the simulated power outputs are basically in agreement with the results calculated with the measurements, which validates the mathematical model of the solar chimney thermal power generating system. Furthermore, based on the simulation and the specific construction costs at a specific site, the optimum combination of chimney and collector dimensions can be selected for a required electric power output.
