Control of DFIG-WT under unbalanced grid voltage conditions
Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Lima, Kleber; Córcoles López, Felipe; Watanabe, Edson H.; Teodorescu, R. (2009)
Comunicació de congrés
Accés obertThe voltage oriented control in the synchronous reference frame (VOC-SRF) have been extensively used for controlling wind turbines based on doubly fed induction generators (DFIG-WTs) through the rotor side converter of ... -
Control strategies for DFIG wind turbines under grid fault conditions
Luna Alloza, Álvaro; Rolán Blanco, Alejandro; Medeiros, G.; Rodríguez Cortés, Pedro; Teodorescu, R. (2009)
Comunicació de congrés
Accés obertThe classical control techniques for regulating the active and reactive power delivery in doubly fed induction generators (DFIG), for wind power applications, are normally based on voltage oriented control (VOC) strategies. ... -
Current harmonics cancellation in three-phase four-wire systems by using a four-branch star filtering topology
Rodríguez Cortés, Pedro; Candela García, José Ignacio; Luna Alloza, Álvaro; Asiminoaei, Lucian; Teodorescu, R.; Blaabjerg, F. (2009-08)
Article
Accés obertThis paper presents a new solution for filtering current harmonics in three-phase four-wire networks. The original four-branch star (FBS) filter topology presented in this paper is characterized by a particular layout ... -
Proposal of a resonant controller for a three phase four wire grid-connected shunt hybrid filter
Candela García, José Ignacio; Rodríguez Cortés, Pedro; Luna Alloza, Álvaro; Teodorescu, R.; Blaabjerg, F. (2009-09)
Comunicació de congrés
Accés obertThis paper present a three-phase four wire hybrid filter able to perform a selective cancellation of harmonic currents based on resonant controllers. As it will be shown in this work, this kind of control permits to ...
