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
