摘要(Abstract)：

环境温度不仅影响集热场光热效率,也会通过影响凝汽器背压而影响集热场热电效率,为分析其对太阳能协同燃煤发电(Solar aided coal-fi red power generation,SACPG)系统的性能影响,建立了基于Matlab/Simulink的600 MW太阳能协同燃煤发电系统的机理模型,在性能耦合分析的基础上,研究环境温度对集热器光热、热电和光电效率及协同系统效率和省煤量的影响。研究表明:集热场光电效率随环境温度的升高而先增后减,最佳值是环境温度为0℃时;在完全取代第一段抽汽时,协同系统较原系统效率约提高1.5%,省煤量可超过8.8 g/kWh。
