Research on characteristics of MCFC-GT hybrid system based on total energy concept This paper discusses the working performance of MCFC-GT hybrid system at diffirent work conditions. The results show that the hybrid system is high efficiency but the change range of work conditions is narrow. The work condition can be extended by a variable-speed gas turbine. However, this method of operation weakens the action of bottoming cycle.

2基于总能概念的MCFC-GT混合动力系统特性分析本文讨论了MCFC-GT混合动力系统不同工况下的工作性能，结果表明：MCFC-GT混合动力系统具有较高的发电效率，但系统的工况变化范围较小，可通过调节燃气轮机的转速来改善系统的变工况性能。
