Direct torque control for doubly fed induction machine-based wind turbines under voltage dips and without crowbar protection / Abad, G. in IEEE transactions on energy conversion, Vol. 25 N° 2 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 2 (Juin 2010) . - pp. 586 - 588 Titre : Direct torque control for doubly fed induction machine-based wind turbines under voltage dips and without crowbar protection Type de document : texte imprimé Auteurs : Abad, G., Auteur ; Rodriguez, M.A., Auteur ; Poza, J., Auteur Année de publication : 2010 Article en page(s) : pp. 586 - 588 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : asynchronous  machines;  power  system  control;  rotors;  stators;  torque  control;  wind  turbines Résumé : This letter proposes a rotor flux amplitude reference generation strategy for doubly fed induction machine based wind turbines. It is specially designed to address perturbations, such as voltage dips, keeping controlled the torque of the wind turbine, and considerably reducing the stator and rotor overcurrents during faults. In addition, a direct torque control strategy that provides fast dynamic response accompanies the overall control of the wind turbine. Despite the fact that the proposed control does not totally eliminate the necessity of the typical crowbar protection for this kind of turbines, it eliminates the activation of this protection during low depth voltage dips.

Two-level VSC-based predictive direct power control of the doubly fed induction machine with reduced power ripple at low constant switching frequency / Abad, G. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 570 - 580 Titre : Two-level VSC-based predictive direct power control of the doubly fed induction machine with reduced power ripple at low constant switching frequency Type de document : texte imprimé Auteurs : Abad, G., Auteur ; Rodriguez, M.A., Auteur ; Poza, J., Auteur Année de publication : 2008 Article en page(s) : pp. 570 - 580 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  machines;  machine  vector  control;  power  control;  predictive  control;  transient  response;  voltage  control Résumé : In this paper, a new predictive direct power control (DPC) technique is presented for the doubly fed induction machine (DFIM). Based on this predictive control, the strategy is able to operate at considerably low constant switching frequencies and allows it to perform a power ripple minimization technique, in order to improve the steady-state and transient response behaviors of the machine. In addition to the control technique definition, this paper includes a conceptual analysis of DPC. On the other hand, to validate the control strategy, it will be experimentally compared to the well-known voltage frequency control, the vector control, and the nonpredictive DPC strategy. The comparison will be carried out in terms of the steady-state behavior and transient response capacity, and it will be shown that the proposed predictive DPC technique allows to obtain the combination of the quick dynamic response of direct control techniques, and the benefits of constant switching-frequency-based control techniques.
