      Comunicació de congrés
      Accés obert
      Controlling the thermal losses in the semiconductors ~s well. as the Co~mon Mode Voltage (CMV), are important Issues In the design of power electronics converters for photovoltaic applications. At present time there are ...

    • Modeling and simulation of synchronous machine and its behaviour against voltage sags 

      Aguilar Gaván, Daniel; Luna Alloza, Álvaro; Rolán Blanco, Alejandro; Vázquez Guzmán, Gerardo; Acevedo, Gustavo (2009)
      Comunicació de congrés
      Accés obert
      This paper studies the effects of voltage sags (dips), both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). The vast majority of the electrical power generation systems in the world is consist ...

    • Modeling of a variable speed wind turbine with a permanent magnet synchronous generator 

      Rolán Blanco, Alejandro; Luna Alloza, Álvaro; Vázquez Guzmán, Gerardo; Aguilar Gaván, Daniel; Acevedo, Gustavo (2009)
      Comunicació de congrés
      Accés obert
      The aim of this work is to analyze a typical configuration of a Wind Turbine Generator System (WTGS) equipped with a Variable Speed Generator. Nowadays, doublyfed induction generators are being widely used on WTGS, although ...

    • New control strategy to allow the photovoltaic systems operation under grid faults 

      Azevedo, Gustavo M.S.; Rodríguez Cortés, Pedro; Cavalcanti, Marcelo C.; Vázquez Guzmán, Gerardo; Neves, F. (2009)
      Comunicació de congrés
      Accés obert
      This paper presents a new control strategy that allows the photovoltaic system operation under grid faults without overcurrent and assuring grid sinusoidal currents. The current limiter is made indirectly by using an ...

    • Photovoltaic plants generation improvement using Li-ion batteries as energy buffer

      Text en actes de congrés
      Accés restringit per política de l'editorial
      This paper analyzes the PV power plants operability improvement obtained when introducing energy storage (ES) systems which allow decoupling the power received from the sun on the photovoltaic (PV) panels from the power ...

    • Simulation of wound rotor synchronous machine under voltage sags 

      Aguilar Galván, Daniel; Vázquez Guzmán, Gerardo; Rolán Blanco, Alejandro; Rocabert Delgado, Joan; Córcoles López, Felipe; Rodríguez Cortés, Pedro (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
      Comunicació de congrés
      Accés obert
      This paper presents a study of the Wound Rotor Synchronous Machine (SM) stability under voltage sags (dips). Machine behavior has been analyzed by considering different magnitudes (or depths) and duration of the sag. ...

    • Symmetrical ripple constant common mode voltage modulation strategy for DCM-232 three- phase PV topology 

      Rodríguez Cortés, Pedro; Muñoz Aguilar, Raúl Santiago; Vázquez Guzmán, Gerardo; Candela García, José Ignacio; Aldabas Rubira, Emiliano; Etxeberria Otadui, Ion (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper a modulation strategy for the DCM-232 power converter is proposed. This modulation has as particular a symmetrical ripple and that no common mode currents are presented. Some simulation and experimental ...
