Design of a back-to-back NPC onverter interface for wind turbines with squirrel-cage induction generator / Bueno, E. J. in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 932 - 945 Titre : Design of a back-to-back NPC onverter interface for wind turbines with squirrel-cage induction generator Type de document : texte imprimé Auteurs : Bueno, E. J., Auteur ; Cobreces, S., Auteur ; Rodriguez, F.J., Auteur Année de publication : 2008 Article en page(s) : pp. 932 - 945 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  power  convertors;  power  electronics;  power  generation  faults;  power  grids;  wind  power;  wind  turbines Résumé : As the number of wind power applications with power electronic interfaces in the grid increases, it is becoming unacceptable to disconnect the generating units every time disturbances occur, especially under voltage dips, as was a common practice in the past. Keeping the converter online during unbalanced voltage, and guaranteeing the actual standards of the converter connected to the grid, is becoming a very critical issue. From these goals, the design of a robust back-to-back neutral point clamped (three levels) voltage source converter of 150 kVA is developed in this paper. The converter is divided into two main parts: the power electronic system and the control electronic system. Concerning the first part, on the one hand, the paper presents the designs of active and passive components as insulated gate bipolar transistor, free-wheeling diodes, clamping diodes, grid filter, DC-bus capacitors, etc.; and on the other hand, the converter requirements are analyzed to ride through real grid conditions, i.e., unbalanced voltage dips. Concerning the control electronic system, the chosen electronic structure and the task distribution between the two processors used are shown.
