Model-based digital generator control unit for a variable frequency synchronous generator with brushless exciter / Rosado, S. in IEEE transactions on energy conversion, Vol. 23 N°1 (Mars 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 N°1 (Mars 2008) . - pp. 42 - 52 Titre : Model-based digital generator control unit for a variable frequency synchronous generator with brushless exciter Type de document : texte imprimé Auteurs : Rosado, S., Auteur ; Xiangfei Ma, Auteur ; Francis, G., Auteur Année de publication : 2008 Article en page(s) : pp. 42 - 52 Note générale : Energt conversion Langues : Anglais (eng) Mots-clés : Brushless  machines;  digital  control;  digital  signal  processing  chips;  exciters;  synchronous  generators;  voltage  regulators Résumé : This paper presents the design and implementation of a digital signal processor (DSP)-based generator control unit (GCU) for a variable frequency synchronous generator with brush-less exciter. A novel model-based control algorithm is proposed to better account for the wide operating frequency range and various load conditions. In addition to the model-based inner-loop exciter field current regulator and outer-loop generator voltage regulator, the control algorithm also adopts a generator-model-based d-axis current feed-forward loop to compensate for the load disturbance. Simulation and test results show a considerable performance improvement for the new controller when compared to the existing controllers, including better dynamics, better damping stability margin, and more uniform response over the operating range.
