Control of the reactive power supplied by a matrix converter / Cardenas, R. 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. 301 - 303 Titre : Control of the reactive power supplied by a matrix converter Type de document : texte imprimé Auteurs : Cardenas, R., Auteur ; Pena, R., Auteur ; Clare, J., Auteur Année de publication : 2009 Article en page(s) : pp. 301 - 303 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  matrix  convertors;  nonlinear  control  systems;  observers;  power  generation  control;  power  grids;  reactive  power  control;  wind  power  plants;  wind  turbines Résumé : In this paper, the control of the reactive power supplied by a matrix converter to a grid is presented. A matrix converter is used to feed an induction generator using a space vector modulation algorithm. An input current observer, implemented using an estimation of the modulation matrix, is used in a nonlinear controller that regulates the reactive power supplied to the grid by a variable-speed wind energy conversion system (WECS). The results obtained are experimentally validated using a 2 kW experimental prototype implemented using a cage machine, a matrix converter and a wind turbine emulator.

Wind–diesel generation using doubly fed induction machines / Pena, R. 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. 202 - 214 Titre : Wind–diesel generation using doubly fed induction machines Type de document : texte imprimé Auteurs : Pena, R., Auteur ; Cardenas, R., Auteur ; Proboste, J., Auteur Année de publication : 2008 Article en page(s) : pp. 202 - 214 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  diesel  engines;  frequency  control;  hybrid  power  systems;  machine  vector  control;  power  generation  control;  voltage  control;  wind  turbines Résumé : In this paper, the modeling and control strategy of a wind-diesel generation system are discussed. In the proposed topology, the diesel engine and the wind turbine are both variable-speed machines, allowing maximum fuel efficiency and optimal energy capture from the wind. A vector-controlled doubly fed induction generator is used in each generation system to provide fixed voltage and frequency to the load. The diesel unit balances the system power and changes the speed according to the power demand in order to minimize the fuel consumption. The electrical torque of the wind system generator is regulated to maximize the energy capture of the wind turbine. The advantages of operating a diesel engine at variable speed are discussed. The dynamic and steady-state operation of the wind-diesel system, including voltage and frequency control, active power balancing, and control of the reactive power supplied to the grid/load are analyzed in this paper. Experimental results, from a 3-kW experimental prototype are presented in this paper.
