12:00 - 13:30 Loads and fatigue
Turbine technology  
Onshore      Offshore    


Room: Montmartre

The session will discuss the following topics:

  • Analysis of actual wind turbine failures, of blades and towers, due to super typhoon Usagi
  • Detailed simulation of floating offshore wind turbine using coupled CFD, SPH and multibody models
  • Contribution of wake effects on the fatigue loads at above rated wind speeds
  • Development and testing of video-based motion analysis at wind turbine

Learning objectives

Delegates will be able to:

  • understand possible rootcause and load conditions that can lead  to wind turbine structural failure during typhoon
  • become familiar with the simulation methodology that combine detailed fluid-structure interaction models for floating wind turbines
  • understand the contribution of the wake effects for the fatigue load and how to take that into account using DWM model
  • assess the advantages of video-based motion analysis and its practical applications for wind turbines

Presenter's biography

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

Torben Larsen is senior scientist and team leader at DTU Wind Energy and has 16years of experience with load simulations on wind turbines. He is one of the key developers of the aeroelastic code HAWC2 with special emphasis on aerodynamic, hydrodynamics, control and wake effects. He has been highly involved with the development of the Dynamic Wake Meander model of wind turbine wake effects, which is now part of the new IEC standard for load simulations of wind turbines.
