Machines and drives comparison for low-power renewable energy and oscillating applications / Brekken, T. K. A. 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. 1162 - 1170 Titre : Machines and drives comparison for low-power renewable energy and oscillating applications Type de document : texte imprimé Auteurs : Brekken, T. K. A., Auteur ; Hapke, H. M., Auteur ; Stillinger, C., Auteur Année de publication : 2011 Article en page(s) : pp. 1162 - 1170 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  machines;  brushless  machines;  reluctance  motor  drives;  renewable  energy  sources;  wave  power  generation Résumé : The objective of this paper is to analyze, test, and compare machines and drives in oscillating applications. In particular, this paper is focused on low-power wave energy generator applications, such as autonomous weather and monitoring buoys with power requirements in the 100 W and less range. Due to the oscillating motion of waves, the ocean environment can require bidirectional and variable speed operation of the generator. In this research, the efficiency of a set of small brushed dc, induction, brushless dc, and synchronous reluctance drives and machines were compared in constant and oscillating operation. The presented results show that drives and machines used in low-power oscillating applications (e.g., ocean wave energy) should not expect a significant derating with respect to their nameplate rating. In addition, it is shown that the frequency of oscillation (e.g., ocean wave frequency) has little impact on efficiency.
