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。
Six direct steam generation in parabolic trough collectors (DSG-PTC) systems with different capacities and processes were designed. The integrated solar power system with DSG-PTC as auxiliary heat source was proposed Integrated Integrated Cycle Integrated System (ISCCS). Based on the research results obtained, the real-time dynamic simulation model of ISCCS system is studied. The operational characteristics of ISCCS system were analyzed from the system level using the model, which reflected the matching law of the working fluid and the energy flow between the two energy systems. The applicability of the control system in ISCCS was revealed and some suggestions for improvement of the control strategy were proposed. System dynamic response characteristics, proposed ISCCS system improvements; from the perspective of thermodynamics calculation and analysis of different integrated ways of ISCCS thermal economy, and gives the best integration scheme.
