达汉，开创性的1 MWe CRS（中央接收系统）项目，目前正在北京八达岭长城脚下建设。集热器与太阳能中央接收器耦合系统是塔式太阳能电站中最重要的组成部分，在辐射热转换中起着主导作用。它的性能直接影响到整个太阳能发电系统的效率。本文采用模块化建模方法，对关键部件“收集器和空腔接收器”进行了全面的建模。基于“星星-90”仿真平台，采用面积通量匹配法将两个模型耦合起来。模拟了春分正午静态热流密度分布的模拟结果和不同扰动下的动态响应曲线。结果表明，该方法可以为整个太阳能热发电塔系统的运行和控制系统设计提供很好的参考。
DAHAN, the pioneer 1MWe CRS (Central Receiver System) project, is now under construction at the foot of the Great Wall of Badaling in Beijing. The coupled system-collector and solar central receiver, which plays a dominant role in the radiation-heat conversion, is the most important component in the solar tower plant. Its performance can affect directly the efficiency of the entire solar power generation system. In this paper, the models of the key parts “collector and cavity receiver” were fully developed through the modular modeling method. By adopting the area to flux matching method, the two models were coupled together based on the “STAR-90” simulation platform. The simulation results of static heat flux density distribution at equinox noon and the dynamic response curves under different disturbances were simulated. The result demonstrates it can provide good references for the operation and control system design of the entire solar thermal power tower system.
