摘要
太阳能燃气联合循环系统(ISCC)将槽式太阳能与燃气轮机联合循环相结合,充分利用太阳能作为中低温加热热源,是提高太阳能发电效率,降低太阳能发电成本,并减少系统CO_2排放的有效途径。本文针对太阳能直接蒸汽发生系统(DSG)与燃气轮机联合循环(CCGT)集成的系统,研究了太阳能蒸发给水份额对系统性能的影响,寻求最佳的系统集成模式,并对其经济性能做了初步的探讨。结果表明,太阳能蒸发给水份额为75%时,系统性能最优。
Integrated Solar Combined Cycle System,which integrates parabolic trough solar technology with combined cycle power plant,is an efficient way to make full use of solar energy,improve system thermal efficiency,save the fossil fuels and reduce CO_2 emission.Based on an Integrated Solar Combined Cycle consisting of a Direct Steam Generation parabolic trough field,this paper analyzes how and where solar energy is input into ISCC system would have impact on the solar and system overall efficiencies.A preliminary economic assessment is also carried out,showing that the optimal system performance can be achieved when the solar heat input is 75% of the total latent heat required for water evaporation.
