DYNAMIC MODELING RESULTS OF A 1 MW MOLTEN CARBONATE FUEL CELL/GAS TURBINE POWER SYSTEM

摘要

A dynamic system model is presented for a 1 MW Molten Carbonate Fuel Cell/Gas Turbine (FC/GT) hybrid power generation system. Results are shown for both a fuel step reduction at the anode inlet, and a voltage step reduction to the fuel cell. Results showed significant thermal consequences at the cathode inlet for both perturbations. To mitigate these thermal consequences, methods of airflow management were examined and indicated that reducing the total gas turbine air flow worked better than an air bleed arrangement. As one option for air flow management, a control for the turbine speed was studied. These results are also presented showing that the thermal conditions are managed far better with such a control method.
