Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 15 - 24 Titre : Transient modeling and parameter estimation of field aligned starting Type de document : texte imprimé Auteurs : Madawala, U.K., Auteur ; Baguley, C. A., Auteur Année de publication : 2008 Article en page(s) : pp. 15 - 24 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Machine theory  squirrel cage motors  starting  transient analysis Résumé : Field aligned starting (FAS) is a new technique for starting three-phase cage induction motors on single-phase supply lines with minimal inrush currents. It uses a simple energy storage system to generate a very high impulsive torque by which the motor is started before being connected to the mains supply. The spinning motor can then be connected to the mains to operate in a standard Steinmetz connection without incurring high inrush currents, if the moment of mains connection is properly timed. This paper presents a transient model and an accompanying parameter estimation method through which the transient behavior of three-phase induction motors operated with FAS can be analyzed. The proposed model is based on instantaneous symmetrical components and is used to investigate a 3 kW motor started under various operating conditions. The proposed parameter estimation method and the developed transient model are both validated by experimental results.
