塔式太阳能-燃气轮机发电系统发电成本和研发风险都低于常规太阳能热发电系统，同时能克服太阳能随机性、波动性的缺点，可以推动太阳能热发电的商业化进程。为了研究塔式太阳能与燃气轮机发电系统的能量传递与热功转化规律，以及相关结构参数与运行参数对发电系统性能的影响，该文分别建立该系统中压气机、泡沫陶瓷吸热器、燃烧室、透平4部分的传热和热功转化模型，采用Matlab软件平台编程，进行了系统运行仿真模拟，并分析了压比、孔隙率、厚度、吸热器面积、进气温度等对系统性能的影响。研究结果可为系统的设计与运行提供参考。“,”Solar tower-gas turbine power system could push forward the commercialization process of solar thermal power due to its lower cost, lower risk of research and development as well its ability to overcome the random and wave character issues. In order to study the heat transfer and power transformation characters of solar tower-gas turbine power system and the influences of parameters on the system performances, component models of the heat transfer and power transformation were developed for the compression chamber, foam ceramics receiver, combustion chamber and gas turbine. The models were simulated by Matlab software to analyze the influences of pressure ratio, porosity, thickness, foam ceramics receiver surface area and inlet air temperature on the systems. The research can provide some references for the design and operation of the system.
