Voltage and frequency control of a stand alone brushless wind electric generation using generalized impedance controller / Venkatesa Perumal, B. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 632 - 641 Titre : Voltage and frequency control of a stand alone brushless wind electric generation using generalized impedance controller Type de document : texte imprimé Auteurs : Venkatesa Perumal, B., Auteur ; Chatterjee, J. K., Auteur Année de publication : 2008 Article en page(s) : pp. 632 - 641 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : PWM  invertors;  asynchronous  generators;  brushless  machines;  feedback;  frequency  control;  voltage  control;  wind  power  plants Résumé : In this paper, a new strategy for the control of terminal voltage and frequency of a stand-alone self-excited induction generator-(SEIG) based wind generator, working with variable speed and load is proposed. With a generalized impedance controller (GIC) (voltage source pulsewidth-modulated inverter with a dc-link battery), a new strategy to maintain the active and reactive power balance at the SEIG terminals has been introduced to control its terminal voltage and frequency. In the proposed control strategy, only a voltage feedback loop has been used to control both the SEIG terminal voltage and the frequency. A mathematical model of the SEIG-GIC system under wind generator environment has been developed and simulated in the MATLAB/Simulink. The simulation results are validated with the experimental ones conducted on a laboratory prototype of the SEIG-GIC system. The novelty of the present technique is that the GIC is capable of maintaining a constant SEIG terminal voltage and frequency, following both speed and load perturbations, with only a single (voltage) feedback loop.
