The wind power systems of variable velocity using a doubly-fed induction generator dominate large-scale electrical generation within renewable energy sources. The usual control goal of the wind systems consists of maximizing the wind energy capture and streamlining the energy conversion process. In addition, these systems are an intermittent energy source due to the variation of the wind velocity. Consequently, the control system designed to establish a reliable operation of the wind system represents the main challenge. Therefore, emulating the operation of the wind turbine by means of an electric motor is a common strategy so that the controller design is focused on the induction generator and its connection to the utility grid. Thus, we propose to emulate the dynamical operation of a wind turbine through a separately excited DC motor driving by a sensor-less velocity controller. This controller is synthesized based on the state-feedback linearization technique combined with the super-twisting algorithm to set a robust closed-loop system in the presence of external disturbances. A robust velocity observer is designed to estimate the rotor velocity based on the armature current measuring. Furthermore, a robust differentiator is designed for estimating the time derivative of the velocity error variable, achieving a reduction in the computational calculus. Experimental tests were carried using a separately excited DC motor coupled with a dynamometer to validate the proposed wind turbine emulator.

“…Thus, wind turbine emulators (WTE) becomes essential for the technological development of the area, once they are independent of the intermittent nature of the wind. In addition, WTEs are capable of reproducing the same aerodynamic behaviour of real wind turbines [5][6][7].…”

Wind energy is one of the most promising forms of renewable energy. For the constant evolution of power generation technology, the use of sensors is fundamental to the development of wind turbine emulators. A wind turbine emulator allows tests and evaluations of a wind power system, regardless of weather conditions. Therefore, to further improve this technology, this work focuses on the application of a torque transducer and a rotary encoder for the implementation of a closed-loop wind turbine emulator. The sensors provide the torque and speed feedback signals to the computational model so that the model could plot the power curves and produce the set point voltage used by a variable-frequency drive (VFD) to control a three-phase induction motor (TIM). The emulator was implemented using a control algorithm designed on LabVIEW, with an NI 6211 for the data acquisition. Finally, the system emulates the behaviour of a wind turbine, considering the variations in wind speed, aerodynamic phenomena, load effects, and pitch angle. Experimental results demonstrated the effectiveness of using the TIM-VFD assembly for emulating a wind turbine since the wind turbine emulator behaved like a wind turbine in real-time.

En el presente trabajo se diseña e implementa en tiempo real un controlador de velocidad del motor de corriente directa con excitación separada para emular la operación de una turbina eólica. Se define el modelo de la ecuación mecánica de la turbina eólica y del generador eléctrico, además del modelo del motor de corriente directa. Se aplica la técnica de linealización por retroalimentación de estados en combinación con la ley de control super-twisting de modos deslizantes de segundo orden en el diseño del controlador de velocidad en lazo cerrado, el cual sigue la velocidad de salida de un sistema eólico virtual que tiene como entrada un oscilador de viento, y con esto se logra emular la operación de la turbina. Se valida el emulador en tiempo real diseñando un observador asintótico del par de carga del motor de CD, utilizando un grupo motor CD-dinamómetro y el kit DS1103 de dSPACE. Se valida el buen desempeño del emulador de turbina eólica en tiempo real con resultados gráficos del seguimiento de velocidad, de los márgenes de voltaje y corriente en el devanado de armadura, y de la estimación del par de carga con un observador asintótico.
