Resumen

This paper analyses the performance of a variable-speed wind turbine (VSWT) with a doubly fed induction generator (DFIG) when different control strategies are used in the rotor connected converter. For this purpose a model is implemented in Matlab-Simulink. The model is absolutely modular and it is possible to simulate the system with emphasis on different aspects as required. The rotor connected converter must control de DFIG rotor voltage in order to obtain the desired rotational speed and thus extract the maximum power available in the wind. However, if the rotor connected converter has high power losses, slow dynamic response or generates high torque pulsations the benefits of the DFIG configuration may not be cost effective. State of art SVM control techniques are compared with DTC-DPC control techniques. In order to achieve maximum power extraction a higher level controller is implemented. This controller generates de active power, torque and reactive power references for the SVM and DPC controllers.
