Power Criterion for Emulating a Gas Turbine Engine with an Electric Motor
نویسندگان
چکیده
A power criterion for selecting the electric motor used in a gas turbine emulator is defined. The power criterion is derived in terms of the ratio of inertias between the gas turbine engine and the electric motor, rotational losses and load torque. The gas turbine emulator allows emulating the speed-torque behavior of a gas turbine engine. Using simulation models, we show that the steady-state speed response of the gas turbine emulator tracks that of the gas turbine engine. The Bode plots of the gas turbine and gas turbine emulator are obtained by using system identification. Frequency analysis shows that the gas turbine emulator tracks the speed response of the gas turbine within the linear region.
