A series-dynamic-resistor-based converter protection scheme for doubly-fed induction generator during various fault conditions / Jin Yang 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. 422 - 432 Titre : A series-dynamic-resistor-based converter protection scheme for doubly-fed induction generator during various fault conditions Type de document : texte imprimé Auteurs : Jin Yang, Auteur ; Fletcher, J.E., Auteur ; O'Reilly, J., Auteur Année de publication : 2010 Article en page(s) : pp. 422 - 432 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : DC  motor  protection;  asynchronous  generators;  machine  control;  overcurrent  protection;  power  system  CAD Résumé : This paper proposes a new converter protection method, primarily based on a series dynamic resistor (SDR) that avoids the doubly-fed induction generator (DFIG) control being disabled by crowbar protection during fault conditions. A combined converter protection scheme based on the proposed SDR and conventional crowbar is analyzed and discussed. The main protection advantages are due to the series topology when compared with crowbar and dc-chopper protection. Various fault overcurrent conditions (both symmetrical and asymmetrical) are analyzed and used to design the protection in detail, including the switching strategy and coordination with crowbar, and resistance value calculations. PSCAD/EMTDC simulation results show that the proposed method is advantageous for fault overcurrent protection, especially for asymmetrical faults, in which the traditional crowbar protection may malfunction.
