Modelación, Simulación y Control de Aerogeneradores con Generador de Inducción Doblemente Alimentado Utilizando Matlab

Abstract

In this work the modeling of the aerodynamic, mechanic, electric, and control components of the Doubly-Fed Induction Generator (DFIG) Wind Turbine is presented. The modeling is used to create a program in the software Matlab. The fourth order Runge-Kutta method is used to solve the differential equations existing in the modeling. The control strategy of the back-to-back PWM converter is based on the vector control technique with rotating reference frames which allows the control of the DFIG’s active and reactive power. The initialization process of the whole system DFIG Wind Turbine is described in order to obtain the steady state conditions of the system before of starting the simulation. The behavior of the DFIG Wind Turbine is analyzed in the face of wind speed changes and short circuit faults. The final results show that DFIG’s active power varies in accordance to the wind speed’s behavior while its reactive power keeps almost invariant. The results obtained are compared with the results of DFIG Wind Turbine’s basic model existing in Simulink of Matlab.
