【摘要】 本文针对槽式太阳能辅助不同容量燃煤机组的互补耦合发电系统,建立槽式太阳能集热场以及互补系统的数学模型,分析互补发电系统在典型工况以及年热力性能,并以此为基础研究集热场面积及蓄热对互补发电系统热力性能的影响。其结果表明,典型工况下低功率容量的耦合机组节煤效果更好,更能在较小的集热场面积下达到较高的热电效率;而从年性能的角度看,蓄热装置的引入会使互补发电系统的热性能显著提高。更多还原

【Abstract】 In this paper,the performances of a parabolic trough solar field integratedwith various capacity conventional coal-fired plant under typical condition and through a whole year.Based on the analysis of the performance,solar collector field aperture and thermal storage system is studied for the influence of the thermal performance.The results under typical condition show that the lower integrated plant better in saving coal combustion and reach a higher efficiency.The results from annual performance show that SAFCP system operated better apparently after thermal storage system is employed.更多还原
