摘　　要：设计了6套不同容量和流程的直接产生蒸汽型槽式聚光集热系统(direct steam generation in parabolic trough collectors,DSG-PTC);提出以DSG-PTC为辅助热源的整体太阳能联合循环发电系统(integrated solar combined cycle system,ISCCS)的6种集成方案;基于已取得的研究成果,研究ISCCS系统实时动态仿真模型。利用模型从系统层面分析了ISCCS系统的运行特性,反映了2个能源系统间工质流和能量流的匹配规律;揭示控制系统在ISCCS中的适用性并提出了控制策略的改进建议;研究ISCCS系统动态响应特性,提出ISCCS系统改进措施;从热力学的角度计算分析不同集成方式的ISCCS系统热经济性,给出了最佳集成方案。The direct steam generation in parabolic trough collectors systems （DSG-PTC） with different capacities and working-medium flow path were designed. The integration schemes for the integrated solar combined cycle system （ISCCS） taking DSG-PTC as the auxiliary heat source were put forward. The real-time dynamic simulation models for the ISCCS were studied based on the previous research achievements. With these dynamic simulation models, the operating characteristics of ISCCS were analyzed, the matching principle of the working-medium flow and energy flow between two energy systems were indicated, the control strategy improving suggestions in ISCCS are put forward, the dynamic response characteristics of the ISCCS are researched, the thermal economy of the ISCCS in different integration schemes are calculated, and the optimal integration scheme is proposed.
