摘 要: 由于固体氧化物燃料电池(solid oxide fuel cell,SOFC)排出的尾气具有较高的潜热,当它与微型燃气轮机(micro gas turbine,MGT)组成混合系统发电时,系统的发电效率将比SOFC或MGT单独发电时高,因此该系统是一种有很大潜力的分布式发电方案。研究以混合发电系统为对象,建立SOFC、MGT两个子系统的动态模型,分析SOFC模型的电化学特性和热力学性质,并对两个子系统以及耦合系统的性能进行仿真研究。结果表明,本文建立的SOFC-MGT模型稳态性能正常,两个子系统非耦合状态与耦合状态下的动态性能良好,该数值模型为SOFC-MGT混合发电系统的半实物仿真系统构建提供了理论基础,并为混合装置的设计和运行提供了重要参考。

Abstract: Because the exhaust gas discharged from the solid oxide fuel cell (SOFC) has a high latent heat, the power generation efficiency of the system will be higher than that of the SOFC or micro gas turbine (MGT) when it is mixed with a MGT. It has a great potential for distributed power generation program. In this paper, the dynamic mathematical modeling of two subsystems of SOFC and MGT is established based on the SOFC-MGT hybrid power generation system. The electrochemical and thermodynamic properties of the SOFC model are analyzed, and the performances of the two subsystems and the coupled system are simulated and analyzed. The results show that the SOFC-MGT system in this paper has good steady-state performance and dynamic performance in non-coupled state and coupled state of the two subsystems. The research of this paper provides a theoretical basis for the construction of the hardware-in-the-loop simulation system, as well as a important reference for the design and operation of the SOFC-MGT hybrid power generation system.
