14:30 - 16:00 Innovation in wind turbine drive trains
Turbine technology  
Onshore      Offshore    

Room: Montmartre

This session will share new concepts to reduce failures/improve behavior cost-effectively:

  • New configuration of bearingless permanent magnet machine with multiple modules for direct drive to reduce bearing failure
  • Coupled magnetoelastic model of a multipole permanent magnet generator in no-load conditions to reduce weight
  • Potential of MgB2 superconductors on direct drive generators
  • Alternative Wind Turbine Drive Train with Power Split and High-speed Generators 

Learning objectives

  • Delegates will be able to list problems associated to generator systems in direct-drive WTG and identify a new bearingless concept
  • Delegates will be able to list design problems inherent to scaleability and identify a model to capture dynamic phenomena and derive design criteria
  • Delegates will be able to explain cost considerations limiting superconducting direct drive technology and identify potential optimization

Presenter's biography

Biographies are supplied directly by presenters at EWEA 2015 and are published here unedited

Mr. Cristian Andrei received his diploma degree in electrical engineering from the Faculty of Electrical Engineering of the Technical University of Cluj-Napoca, Romania, in 2009. Since 2010, he has been a research associate at the Institute of Electrical Machines (IEM) of the RWTH Aachen University, Germany. His research fields include the technical and economical assessment of wind turbines and their improvement through alternative concepts, with focus on the electrical generator.
