Advanced modeling of a synchronous generator under line-switching and load-rejection tests for isolated grid applications / Wamkeue, R. in IEEE transactions on energy conversion, Vol. 25, N° 3 (Septembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 3 (Septembre 2010) . - pp. 680 - 689 Titre : Advanced modeling of a synchronous generator under line-switching and load-rejection tests for isolated grid applications Type de document : texte imprimé Auteurs : Wamkeue, R., Auteur ; Jolette, C., Auteur ; Kamwa, I., Auteur Année de publication : 2011 Article en page(s) : pp. 680 - 689 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : synchronous  generators Résumé : This paper deals with an efficient method behind the analysis of a saturated synchronous generator (SG) under line-switching and load-rejection tests for islanded networks. This novel approach is based on a SG and ( P,V,Q) load-equivalent combined state-space model. Full and partial load-rejection tests and line-switching tests are explored. The k -factor cross-saturation theory of SG is applied to account for the saturation phenomenon in the proposed model. The paper also attempts to point out the duality between line-switching and load-rejection tests. As the best alternative to the load-rejection test, the line-switching test is simple and more suitable, providing easy steady-state conditions (zero armature currents and rotor angle). Consequently, there is no need for rotor angle positioning when performing the test. Comparisons between simulation results and actual data obtained from a four-pole 1.5-kVA, 208-V, 60-Hz laboratory machine show the effectiveness of the proposed SG stator decrement tests analysis framework.
