Wind Turbine Emulator Based on DC Motor

Abstract

Wind energy emerges as a promising solution for electricity generation, circumventing greenhouse gas emissions. However, the complexities of establishing wind energy conversion systems in a laboratory setting have spurred researchers to contemplate the utilization of wind turbine emulators. These latter afford the capability to accurately replicate the behavior of an actual wind turbine. In this chapter, an intricate description of the selected wind turbine emulator is provided, consisting of a DC motor regulated by a DC-DC buck converter. This converter is controlled by the PWM pulses generated by the wind turbine model. Proficient control of the DC motor allows electric sinusoidal voltage and current to be produced by the asynchronous generator in accordance with the adopted wind profile. Subsequently, the emulator undergoes rigorous implementation and thorough analysis within the MATLAB/Simulink environment to validate the efficiency of its system.
