摘要
在太阳能热气流发电的基础上增设进风口,形成了利用太阳能和风能的太阳能热风发电系统。建立了太阳能热风发电热动力稳态数学模型,通过此模型可判断出发电系统的稳定性,并可解出热风风速、集热棚出口温度及稳态数学模型的其它参数。文章介绍了太阳能热风发电系统的实际运行情况,运行结果与数学模型计算结果相吻合。理论分析和运行实践表明,提高塔筒高度、加大塔筒内外温差、增加集热棚的太阳能吸收率、增大集热棚面积系数及风力发电机组的风能利用率,是提高太阳能热风发电量的途径。
A solar heated wind updraft tower power plant （SHWUTPP） is designed based on the solar updraft tower power by adding some controllable air intakes at the HCS rim, so it can apply both solar generation and natural wind generation. In this paper a mathematical model of the power plant is established to judge the stability of this system, deduce the speed of the heated wind, get the temperature of the heat collecting shed outlet and other relevant parameters. The real operational aspect of this sys- tem is described, and it is consistent with the mathematical model. By rationally analysis and the re- sult of the generation operation, such as improving the height of the tower, increasing the difference of the temperature between the inside and outside of the tower, increasing the area and solar absorption coefficient of the heat collecting shed, improving the utilization of wind energy are the ways to increase the generation capacity.
