摘　　要：太阳能与燃煤互补发电方式是近年来大规模太阳能热利用的发展方向之一。以槽式太阳能集热系统辅助某330MW燃煤机组替代高加回热抽汽加热给水的互补发电系统为例，对功率不变型互补发电系统的设计点热力性能及年热力性能进行了分析。结果表明，太阳能辅助发电系统的年光电转换效率可达到20.41%，高于单纯槽式太阳能热发电方式。在此基础上，以内部收益率（internal rate of return，IRR）作为评价指标，运用技术经济的基本原理对太阳能辅助燃煤机组互补发电系统的经济性能及其主要影响因素进行了定量的分析评价,得到了太阳能上网电价、集热器造价、燃料成本等关键因素对内部收益率的影响。
The solar aided coal-fired power generation system is one of the trends of the solar thermal applications on a large scale recently. The performance of a solar trough collector aided 330MW plant with part of extraction steam in high-pressure （HP） heaters replaced was analyzed as an example. The design point and typical annual performance of solar aided coal-fired power generation in fuel-saving operation mode was analyzed. The results show that the performance of solar aided coal-fired power generation system is superior to trough solar thermal power unit and the solar to power efficiency can reach 20.41%. On this basis, the economic benefits of the solar aided coal-fired power generation system was analyzed with internal rate of return （IRR） as index by using the fundamental theories of techno-economy, and the main factors which affect the project economy were evaluated quantitatively. The influences of electricity prices, collector prices, fuel prices on IRR were gained.
