Control of STATCOM in wind power plants based on induction generators during asymmetrical grid faults
Rodríguez Cortés, Pedro; Luna Alloza, Álvaro; Medeiros, G.; Teodorescu, Remus; Blaabjerg, F. (2010)
Text en actes de congrés
Accés obertThis paper explores different strategies to set the reference current of a STATCOM under unbalanced grid voltage conditions. The aim of the proposed control strategies is to provide a set of reactive current references ... -
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 ... -
Four-branch star neutral current hybrid power filter and var compensator
Rodríguez Cortés, Pedro; Candela García, José Ignacio; Luna Alloza, Álvaro; Teodorescu, Remus; Blaabjerg, F.; Rocabert Delgado, Joan (2010)
Text en actes de congrés
Accés obertThis paper presents a solution for filtering current harmonics in three-phase four-wire networks based on the usage of a four-branch star (FBS) filter topology. The specific layout of single-phase inductors and capacitors ... -
Multi-resonant frequency-locked loop for grid synchronization of power converters under distorted grid conditions
Rodríguez Cortés, Pedro; Luna Alloza, Álvaro; Candela García, José Ignacio; Mujal-Rosas, Ramon Maria; Teodorescu, Remus; Blaabjerg, F. (IEEE Press. Institute of Electrical and Electronics Engineers, 2011-01)
Article
Accés obertThis paper presents a new multiresonant frequencyadaptive synchronization method for grid-connected power converters that allows estimating not only the positive- and negative-sequence components of the power signal at ... -
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 ... -
Rotor voltage dynamics in the doubly fed induction generator during grid faults
Lima, Francisco F. A.; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Watanabe, Edson H.; Blaabjerg, F. (2010-01-29)
Article
Accés obertThis paper presents a new control strategy for the rotor-side converter (RSC) of wind turbines (WTs) based on doubly fed induction generators (DFIG) that intends to improve its low-voltage ride through capability. The ...
