太阳能燃气蒸汽联合循环系统变工况性能研究

Performance study on variable working conditions of solar gas-steam combined cycle system

针对一体化太阳能与燃气轮机联合系统(ISCC),通过Ebsilon软件对系统建模进行模拟研究,分析了太阳能集热场与联合循环系统的热力学性能与运行特点,以3种方案对比了不同集成方式下系统排烟温度、循环热效率的区别,探寻了太阳能联合系统的普遍规律,以实现更高的能源利用率。

Aiming at the integrated solar and gas turbine combined system(ISCC), the system modeling is simulated by Ebsilon software, and the thermodynamic performance and operating characteristics of the solar collector field and the combined cycle system are analyzed. The three schemes are compared under different integration methods. The difference between the exhaust gas temperature and cycle thermal efficiency of the system explores the universal law of the solar combined system to achieve higher energy efficiency.
