This paper presents performance analysis of a hybrid power generation system consisting of a solid oxide fuel cell (SOFC) and a steam injected gas turbine (GT) based on the commercial software Easy5. The steam is produced by using the hot exhaust gases heat in the heat recovery steam generator (HRSG) and is injected into the afterburner. Compared with the system without HRSG, the exhaust gas temperature decreases slightly and the power output of the gas turbine is higher because of the increase of the inlet mass flow rate. In addition, the heat exchanger reformer is used in the hybrid system to reduce space and cost. Simulation results show that the hybrid system could achieve a system efficiency of 62.6% under full load operation. And the part load and the dynamic performance of the hybrid system was presented and analyzed.
