摘要
通过对聚光器、接收器和斯特林机等模块进行分析,得到了各模块之间的函数关系,建立了碟式太阳能热发电系统的能量传递模型,运用该模型对碟式太阳能热发电系统在不同气候条件下的性能进行了仿真分析。结果表明,斯特林机压力与太阳直接辐射强度呈线性增大关系;当斯特林机热头温度保持在设定值范围内时,系统净输出功率随斯特林机压力的增大而升高;当环境温度降低时,斯特林机效率和系统净输出功率均有所升高,但系统净输出功率升高幅度不大;当风速增大时,接收器效率及系统净输出功率均降低。
Through an analysis on concentrator, receiver and Stirling engine, the functional relationships among each modules were obtained, the energy tranfer model of dish solar thermal power system was built.The simulation and anal-ysis on the performances of dish Stirling system were carried out under different climates conditions by using energy transfer model.The results showed that the engine pressure exhibited linear relationship with the solar direct normal in-solation;when the hot-head temperature kept in setting range, the net output power of the system increased with the en-gine pressure increasing;while the ambient temperature decreased, the Stirling engine efficiency increased and the net output power increased slightly; while the wind speed increased, the receiver efficiency and the net output power increased.
