摘要
对太阳能热气流电站系统进行了热力学理论分析,将整个系统分成集热棚,风力透平和烟囱三个子区域,分析每个子区域内工质热力学过程,研究各参数变化影响因素,并对系统压力场进行分析.首次提出了能量利用度的概念,并对不同尺寸的太阳能热气流电站的性能进行了分析计算.结果表明:太阳辐射能和涡轮机负荷对系统能量利用度有显著影响,而且系统能量利用度随着太阳能热气流电站的规模增大而增大.该计算结果将为建设不同规模的太阳能热气流电站提供理论依据.
Ther modynamics analysis has been made on the solan chimney pewer plant system（SCPPS） in this paper. The whole system has been devided into three sub-regions： the cellector, the turbine and chimney. Both the thermodynamic process and pressure profile of the air in each sub-region were studied to find the relationship among the parameters. After the concept of energy utilization degree of SCPPS was given,the performance of SCPPS with different sizes was analyzed. The results showed that the solar radiation and the pressure difference of the turbine would influence the energy utilization degree markedly, and the degree would increase with the increase of the size of SCPPS, proving the theoretical reference to the design of SCPPS.
