Optimal control of matrix-converter-based WECS for performance enhancement and efficiency optimization / V. Kumar in IEEE transactions on energy conversion, Vol. 24 N°1 (Mars 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N°1 (Mars 2009) . - pp. 264 - 273 Titre : Optimal control of matrix-converter-based WECS for performance enhancement and efficiency optimization Type de document : texte imprimé Auteurs : V. Kumar, Auteur ; Joshi, R. R., Auteur ; Bansal, R. C., Auteur Année de publication : 2009 Article en page(s) : pp. 264 - 273 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  fuzzy  control;  matrix  convertors;  optimal  control;  optimisation;  power  factor;  power  generation  control;  power  grids;  wind  power  plants;  wind  turbines Résumé : This paper describes a new wind energy conversion scheme, where fuzzy logic principles and four-leg-improved novel matrix converter (MC) model are used for performance enhancement and efficiency optimization, particularly for sites where most of the time low wind speeds prevail. The MC is intended as the interface medium between the induction generator and the utility grid. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal utilization of the installed wind turbine capacity. The generation system has fuzzy logic control with vector control in the inner loops. Fuzzy controller tracks the angular frequency with the wind velocity to extract the maximum power and programs the machine flux for light load efficiency improvement. The complete control system has been developed, analyzed, and validated by simulation study.
