    • An ensemble learning solution for predicitive manintenance of wind turbines main bearing 

      Beretta, Mattia; Julian, Anatole Alexandre; Sepúlveda, José; Cusidó Roura, Jordi; Porro Martorell, Olga (Multidisciplinary Digital Publishing Institute (MDPI), 2021-02)
      Article
      Accés obert
      A novel and innovative solution addressing wind turbines’ main bearing failure predictions using SCADA data is presented. This methodology enables to cut setup times and has more flexible requirements when compared to the ...

    • Effects of the pre-processing algorithms in fault diagnosis of wind turbines 

      Marti Puig, Pere; Blanco Martínez, Alejandro; Cárdenas Araújo, Juan José; Cusidó Roura, Jordi; Sole Casals, Jordi (Elsevier, 2018-12)
      Article
      Accés obert
      The wind sectors pends roughly 2200M€ in repair the wind turbines failures. These failures do not contribute to the goal of reducing greenhouse gases emissions. The 25–35% of the generation costs are operation and maintenance ...

      Text en actes de congrés
      Accés obert
      LCOE reduction in FOWTs is heading to larger wind turbines in order to increase power production and capacity. NREL and DTU have recently developed a 15MW reference wind turbine, which can be used to validate the platform ...

    • New solution to prevent excessive wear in wind turbine gears 

      Farré Lladós, Josep; Westerberg, Lars; Casals Terré, Jasmina (Curran, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      During wind turbines operation, yaw and pitch bearings suffer from sequential traction-compression stresses causing millions of micro movements per cycle between the gear teeth. This situation reduces the lubricant thickness ...
