Estimation of hydropower generator parameters through field simulations of standard tests / Lidenholm, J. 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. 931 - 939 Titre : Estimation of hydropower generator parameters through field simulations of standard tests Type de document : texte imprimé Auteurs : Lidenholm, J., Auteur ; Lundin, U., Auteur Année de publication : 2011 Article en page(s) : pp. 931 - 939 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Finite  element  analysis;  hydroelectric  power  stations;  synchronous  generators Résumé : Four standard test procedures-the three phase short-circuit test , the field decrement test, the slip test, and the applied voltage test-for estimation of synchronous generator parameters have been implemented in a time-stepping finite-element software. In this paper, the main features of the implementation and the postprocessing of data are described. The validity of the application is demonstrated by comparison with test results from the commissioning of a large hydropower generator. The method is shown to be effective in estimating most parameters. Better representation of the exciter and the interpole connections of the damper circuit is believed to enhance the compliance even further.
