摘　　要：文章基于联合海水淡化和余热的风力增压式太阳能烟囱发电综合系统(WSCPPDW),构建了能够描述其运行特性和经济性能的数学模型,研究表明:烟气余热的利用,使得WSCPPDW的发电和产水性能优于大多数水电联产的太阳能烟囱电站(SCPP)综合系统,其发电量为193.7 kW,产水量17.2 t/h,能量综合利用效率13.5%。风力增压装置使得WSCPPDW总净利润和总净现值分别增大了21.6%和14.7%,提前3 a进入盈利期。WSCPPDW年净收益均呈逐年递增的趋势,年净现值先增大后减小,除了第1年为负值外,在剩余的服役期间内均大于零。WSCPPDW同时利用风能、太阳能和烟气余热多种形式能源,在低辐射状态下能够连续、稳定地工作。Based on the wind-supercharged solar chimney power plant combined with seawater desalination and waste heat(WSCPPDW),a mathematical model was constructed to describe its operating characteristics and economic performance.The results show that the utilization of the waste heat of flue gas makes the power generation and freshwater output performance of WSCPPDW superior to those of most SCPP integrated systems that can realize water and electricity co-generation.WSCPPDW has 193.7 kW of power generation,17.2 t/h of hourly water production,13.5%of energy comprehensive utilization efficiency.The wind supercharging device increases the total net profit and the total net present value of WSCPPDW by 21.6%and 14.7%respectively,and allows it to enter a profitable period 3 years in advance.The annual net income of WSCPPDW is increasing year by year,and the annual net present value increases first and then decreases.The annual net profit and annual net present value of WSCPPDW are negative in the first year of the system’s operation,but were positive for the rest of its service life.WSCPPDW realizes the simultaneous utilization of wind energy,solar energy and waste heat of flue gas,and can work continuously and stably under low radiation condition.
