Voltage-sag tolerance of DFIG wind turbine with a series grid side passive-impedance network / Xiangwu Yan in IEEE transactions on energy conversion, Vol. 25, N° 4 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 4 (Décembre 2010) . - pp. 1048 - 1056 Titre : Voltage-sag tolerance of DFIG wind turbine with a series grid side passive-impedance network Type de document : texte imprimé Auteurs : Xiangwu Yan, Auteur ; Venkataramanan, G., Auteur ; Flannery, P. S., Auteur Année de publication : 2011 Article en page(s) : pp. 1048 - 1056 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  power  supply  quality;  wind  turbines Résumé : Due to the increase of the number of wind turbines connected directly to the electric utility grid, new regulator codes have been issued that require low-voltage ride-through capability for wind turbines so that they can remain online and support the electric grid during voltage sags. Conventional ride-through techniques for the doubly fed induction generator (DFIG) architecture result in compromised control of the turbine shaft and grid current during fault events. In this paper, a series passive-impedance network at the stator side of a DFIG wind turbine is presented. It is easy to control, capable of off-line operation for high efficiency, and low cost for manufacturing and maintenance. The balanced and unbalanced fault responses of a DFIG wind turbine with a series grid side passive-impedance network are examined using computer simulations and hardware experiments.
