摘　　要：该文基于exergy分析的理论,在IPSEpro仿真环境下建立了顶层熔融碳酸盐燃料电池/微型燃气轮机联合发电系统稳态性能仿真模型。利用该模型对顶层系统在额定工况和变工况下的稳态性能进行了仿真研究。仿真结果表明,顶层熔融碳酸盐燃料电池/微型燃气轮机联合发电系统具有较高的效率,额定工况下的exergy效率为57.4%。并具有良好的变负荷特性,变负荷时exergy效率始终维持在56%以上,适用于分布式供能系统。Based on the theory of exergy analysis, a steady - state thermodynamic model for MCFC/MGT hybrid power system is developed on the IPSEpro simulation platform and applied to a performance analysis. The exergy analysis has been carried out along with the performance assessment. The coupling of MGT with a MCFC reactor （ about 50kw） has shown a potential for an efficiency of 57.3% at design point. The results show that the hybrid power system has very good off- design performance. Under part load condition, the efficiency of energy exchange changes very little. It remains over 56%. This is very important to the distributed generation system.
