Modeling and simulation of an emulator of a wind turbine using vector speed control of a three-phase induction motor

Among the renewable energy sources, wind power has gained a prominent position worldwide due to the increasing application in the conversion into electric energy. The wind electricity generation has become the object of study of the impacts on the power grid of a generation with variable output power. This paper aims to model and simulate a wind turbine emulator using a three-phase induction motor (TIM) of squirrel cage rotor, which operates with variable speed. The direct field-oriented control (DFOC) has been applied to control the TIM speed. The flux observer used was the current-voltage model. Simulations in the MATLAB/Simulink simulator, using real wind speed data, made the full system validation. The simulation results have shown that the used control strategy responded satisfactorily to the wind speeds by observing an immediate follow-up of the reference speeds.
