A dead-beat current controller based wind turbine emulator

Abstract

The paper presents the development of a wind turbine emulator, which consists of an induction motor driven by a torque control inverter, and the dead-beat controller plays an important role in this structure. The wind turbine emulator system includes the dead-beat current controller, wind speed emulator, mathematical model of wind turbines, model of rotor blade characteristics, and model of tower effect and rotor inertia. The advantages of the emulator are various wind profiles and wind turbines can be simulated as desired in the control software and it is also integrated the data acquisition to verify the control algorithms and display the parameters. The experimental results confirmed the wind turbine simulator could perform satisfactory under steady state wind profile. This approach provides an instantaneous torque output, which is particularly advantageous for the proposed controller.
