    Article
    Open Access
    In a near future when Industry 4.0 is implanted, predictive maintenance will have a much more prominent role than that currently plays in traditional industry. Predictive maintenance is the organized monitoring with periodic ...
  • Photovoltaic inverters with fault ride-through capability 

    Azevedo, Gustavo M.S.; Vázquez, Gerardo; Luna Alloza, Álvaro; Aguilar Galván, Daniel; Rolán Blanco, Alejandro (ISIE, 2009)
    Conference lecture
    Open Access
    This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in ...
  • Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability 

    Aguilar Galván, Daniel; Rolán Blanco, Alejandro; Vázquez, Gerardo; Córcoles López, Felipe; Rodríguez Cortés, Pedro (2009)
    Conference lecture
    Open Access
    This paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ...
  • Behavior of the three-phase induction motor with spiral sheet rotor 

    Mujal-Rosas, Ramon Maria; Boix Aragonès, Oriol; Colom Fajula, Xavier; Rolán Blanco, Alejandro (2009-03)
    Article
    Open Access
    Improvements in torque at low currents using a rotor with spiral sheets are analyzed. Several rotors and stators have been built combining different constructive and mechanical characteristics of the related elements: ...
  • Reduced-order models of squirrel-cage induction generators for fixed-speed wind turbines under unbalanced grid conditions 

    Rolán Blanco, Alejandro; Córcoles López, Felipe; Bogarra Rodríguez, Santiago; Monjo Mur, Lluís; Pedra Durán, Joaquim (2016-06)
    Article
    Open Access
    This paper develops a study of reduced-order models for squirrel-cage induction generators used in the fixed-speed wind turbines. The squirrel-cage of these generators must be modeled with a double-cage for accuracy purposes. ...

    Article
    Open Access
    Nowadays, there is a renewed interest in switched reluctance machines and especially in axial-flux switched reluctance machines (AFSRM). This paper presents a comprehensive design procedure for modular AFSRM with an inner ...
  • Synchronized switching modulation to reduce the DC-link current in SRM drives 

    Cabezuelo, David; Kortabarria, Iñigo; Andreu, Jon; Ugalde, Unai; Blanqué Molina, Balduino; Andrada Gascón, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2020-03-20)
    Article
    Open Access
    Switched Reluctance Machines (SRM) are emerging as a possible alternative in terms of cost and supply stability to rare earth based electric vehicle traction systems. However, because of the huge amounts of energy stored ...
  • Assessment of the impact of electric vehicles on iberian day-ahead electricity market 

    Olivella Rosell, Pol; Bosch Llufriu, Guillermo Ángel; Villafafila Robles, Roberto; Heredero Peris, Daniel; Kovacevic, Mario (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    Electric vehicles (EVs) could become a controllable grid load by using demand side management techniques, but this requires an information and communications technology (ICT) infrastructure and aggregator agents, to ...
  • Doubly fed induction generator-based variable-speed wind turbine: proposal of a simplified model under a faulty grid with short-duration faults 

    Rolán Blanco, Alejandro; Pedra Durán, Joaquim (2019-08)
    Article
    Open Access
    The aim of this study is to provide a simplified model of a variable-speed wind turbine (VSWT) with the technology of a doubly-fed induction generator (DFIG) which operates under faulty grid conditions. A simplified model ...
  • Initialization of DFIG wind turbines with a phasor-based approach 

    Rolán Blanco, Alejandro; Pedra Durán, Joaquim (2019-03)
    Article
    Open Access
    The objective of this paper is to propose a simple approach to solve the steady state of a wind turbine (WT) equipped with a doubly-fed induction generator (DFIG) which can be used to initialize dynamic studies of the ...
  • Charging/discharging process for electric vehicles: proposal and emulation 

    Barnola Sampera, Miquel; Heredero Peris, Daniel; Villafafila Robles, Roberto; Montesinos Miracle, Daniel; Bergas Jané, Joan Gabriel; Vidal Tejedor, Narcís (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    This paper proposes a charging/discharging process for electric vehicles according to mode 4, specifically based on the CHAdeMO protocol. These initiatives will enable acceptably fast charging of EVs. The proposal has been ...
  • A sensor-less sliding mode control scheme for a stand-alone wound rotor synchronous generator under unbalanced load conditions
