Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 25 N° 1 (Mars 2010) . - pp. 34 - 48 Titre : Development and validation of a comprehensive synchronous machine model for a real-time environment Type de document : texte imprimé Auteurs : A. B. Dehkordi, Auteur ; Neti, P., Auteur ; Gole, A.M., Auteur Année de publication : 2010 Article en page(s) : pp. 34 - 48 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : fault diagnosis  finite element analysis  machine theory  windings  synchronous machines Résumé : A comprehensive model of a salient-pole synchronous machine is developed for a real-time environment. By obtaining the effective specific permeance of the machine from simple experimental measurements and the exact geometry of the rotor pole arc, a model is developed that includes the exact distribution of windings and operating-point-dependent saturation. This model offers a superior simulated response of the machine for fault transients, as well as for steady-state harmonic behavior, and is suitable for the closed-loop testing of relays and controls. The inductances of the machine are computed using the modified winding function approach and validated using finite-element analysis. Finally, the performance of the model is validated under healthy and faulted conditions by comparison with tests on an actual machine.
