摘要：

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. ©2015 Chin. Soc. for Elec. Eng.
