Symposium Vibration of Wind Turbines 2022

Last year the 11th symposium “Vibration of Wind Turbines 2020” was cancelled due to Covid-19. This forum for experts and users from industry and science, which has been running successfully for more than 10 years, has been postponed from autumn 2021 to spring 2022 and will be held in a new and attractive environment on May 5 and 6, 2022. The conference will be professionally designed and moderated by the members of the program committee. The administration and organization is being provided by the Wölfel Group.  

The brand essence continues to combine the classic topics of vibration control technology with wind energy and provide answers to current issues such as increasing reliability and the optimization of maintenance – keyword “Predictive Maintenance”. However, the subject area will be expanded to include the field of “acoustics” in order to cover the complete spectrum of vibrations.

Investigation of dynamic loads in wind turbine (WT) drive trains due to grid and power converter faults

  • a three phase short circuit converter fault leads to a rapid increase of the electromagnetic generator torque, which decreases highly dynamic
  • as a result there are oscillations within the WT drive train, which may lead to component damages (e.g. smearing in the gearbox bearings)
