太阳能光热发电现状及超临界CO2光热发电技术应用前景

Development status of solar thermal power generation and prospect of supercritical carbon dioxide technology applied in it

太阳能光热发电技术具有调度方式灵活、可显著减少弃光、易与其他可再生能源互补发电等优势,美国等国家对太阳能光热发电技术的研究和规模化应用较早,我国在太阳能光热发电方面研究、利用较晚,但近年来发展速度较快,并呈现出与美国等国家不同的特点。对近年来美国和中国光热发电技术的发展历程进行了概述,详细分析了适合光热发电技术的超临界CO2布雷顿循环发电系统的特点、优势,并对其应用前景进行了展望。

Solar thermal power generation technology is of flexible dispatching mode,and can greatly alleviate the abandon of solar power,and is highly complementary with other renewable energy.Research and scale application of solar thermal power generation technology developed early in America,but started late in China.However,the technology is thriving in China and shows distinguished characteristics from that in America and other countries.After introducing the development of solar thermal power generation technology in America and China in recent years,the characteristics and advantages of applying supercritical carbon dioxide Brayton cycle in solar thermal power generation is analyzed,and its prospect in power generation system is expounded.
