摘要: 太阳能热风发电不仅能够进行太阳能发电，而且能够进行自然风能发电．本文建立了太阳能热风发电热动力稳态数学模型，导出了集热棚吸收能量的功率方程和塔筒结构特征方程，仅应用这两个方程，可方便得出数学模型的解，并可容易理解提高发电能力的途径．该数学模型指导了乌海太阳能热风发电系统的建设，该发电系统于2010 年10 月并网发电，发电运行结果与建立的数学模型计算结果相吻合．提高太阳能热风发电量的途径是升高塔筒高度、提高集热棚吸收能量的功率．增大集热棚面积和面积系数以及提高集热棚太阳能吸收率，可以提高集热棚的吸收功率．

Key words: the heated wind updraft tower power; steady-state mathematical model; the heat collecting shed power characteristics; the tower structure characteristics Abstract: The solar heated wind updraft tower power can not only be used for solar power，but also for natural wind power． The steadystate
mathematical model of the solar heated wind updraft tower power was established，and the equations of the heat collecting shed power absorption characteristics and the tower structure characteristics were developed． By using the two equations，the solutions of the mathematical model can be easily deduced and the way to increasing the generating capacity was understood． The mathematical model
provided guidance for the construction of the solar heated wind updraft tower power system in Wuhai． After combining this power system to the grid in October 2010，the results of the generating operation in this system were found in consistent with the calculation results ofthe mathematical model． The ways to improve the generating capacity of the solar heated wind updraft tower power are to increase the height of the tower and add the heat collecting shed power absorbability． By enhancing the area of the heat collecting shed and the area index，together with improving the solar absorption efficiency of the heat collecting shed，the heat collecting shed power absorbability can be increased．
