Ride-through control of a doubly fed induction generator under unbalanced voltage sags / Gomis-Bellmunt, O. in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1036 - 1045 Titre : Ride-through control of a doubly fed induction generator under unbalanced voltage sags Type de document : texte imprimé Auteurs : Gomis-Bellmunt, O., Auteur ; Junyent-Ferre, A., Auteur ; Sumper, A., Auteur Année de publication : 2009 Article en page(s) : pp. 1036 - 1045 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  machine  vector  control;  power  convertors;  power  generation  control;  power  grids;  power  supply  quality;  wind  power  plants Résumé : This paper deals with the control of doubly fed induction generators to ride through unbalanced voltage sags. A control strategy is proposed by choosing certain current reference values in the positive and negative sequences so that the torque and the DC voltage are kept stable during such unbalanced sags. Both rotor- and grid-side converters are considered, detailing the control scheme of each converter while considering the effect of the crowbar protection. The control strategy is validated by means of simulations.
