摘　　要：以研究槽式太阳能集热系统在我国典型气候环境下的热力特性以及对环境的适应能力为出发点,基于我国在甘肃建立的首个太阳能光煤互补示范电站,系统分析了示范电站装机容量为1.5 MW的槽式集热系统,通过理论建模研究示范电站站址气象条件下集热系统的集热性能。根据站址太阳能资源与地理位置,研究了太阳能槽式热发电系统集热系统的集热特性。经计算分析,结论显示槽式太阳能集热系统在设计工况、阵列间距变化、轴向安装角度变化、集热管失去真空等条件下的系统集热特性都会发生较大变化,并得到集热系统特性对不同可能影响参数的影响程度的量化指标。研究结论可以为槽式太阳能集热系统运行及设计提供依据。Based on the purpose of research on thermal characters of parabolic trough system, the paper analyzes the 1.5 MW parabolic trough system in the first solar aided coal-fired demonstration power plant in Gansu province. The model of the system is also been developed and analyzed according to the real climate data and position. The results show that the collector thermal characters are very relevant to the working and installing conditiaons, including designed working condition, different array span, different installation angles and absorbers broken. The different effect degrees of different parameters are also analyzed. The results can be applied to support parabolic trough system operation and design optimization.
