利用热力学方法建立太阳能烟囱发电系统中集热棚、烟囱及风力透平的热气流能量转换过程的理论模型及求解方法。鉴于太阳能烟囱发电站的大尺寸特征，采用一维假设建立热气流传热模型，使用龙格一库塔方法对非线性能量方程进行数值求解。对集热棚直径3600m，烟囱高950m，设计功率100MW的大型太阳能烟囱发电站进行分析与计算，给出了该电站的风力透平轴功率随质量流量和太阳辐射强度变化的规律，为风力透平机组提供热力气动设计参数，为大规模开发利用太阳能提供借鉴。

英文摘要：

By using thermodynamics method, the theoretical and numerical models are established for energy transfer of hot air through heat collector, solar chimney and wind turbine in solar chimney electricity generation system. Owing to the large geometrical scale of the system, one dimensional heat transfer model is assumed in deducing energy equations that are numerically solved by Runge-Kutta method. The thermodynamic model is validated by the thermodynamic calculation of a larger scale solar chimney electricity generation plant with heat collector diameter of 3 600 m, solar chimney height of 950 m and design shaft power of 100 MW. The relationship between shaft output power of wind turbines and mass flow rate is presented at several solar absorption intensity. The working conditions for the wind turbines are also given. This work is of reference for the large-scale exploration and utilization of solar energy.
