摘要：

This paper presents a sensitivity analysis of unsteady-state SOFC-GT-HS operation based oil two different characteristic maps of centrifugal compressor taken from open literature and scaled by tire law Of Similitude to match the design point of the Hybrid System. The system layout under investigation is a pressurised type comprising a low and high temperature recuperator. Computations are based on a one-dimensional finite element model of planar high temperature SOFC, which is validated against open literature. The reduced Moore and Greitzer model is used for compressor modelling. Calculation results of the Coupled SOFC-GT-Hybrid System show that unsteady-state part-load operation is sensitive to the characteristics of compressor speed-lines but also to tire load change operation procedure.
