摘要: This study is focused on a hybrid fuel cell/gas turbine (FC/GT) system with an atmospheric pressure solid oxide cell (SOFC). The impact of the gas rotational speed dynamic performance and controllability investigated. transient response FC/GT to perturbations in power demand has been Two operational strategies turbines are compared: (1) fixed operation, (2) variable operation. For both operation strategies, wide range production numerically simulated. results show that superior for configuration studied. Variable allows 50% turn down no additional balance plant equipment required. efficiency maintained above 66% compared 53% auxiliary combustion.
