King and Queen of the Netherlands visit IWES

On march 6th, we proudly welcomed King Willem-Alexander and Queen Maxima at our site in Bremerhaven, Germany. In the rotor blade test rig, they met the participants of the German Dutch Offshore Wind Days. This event was organized by Wind-Network NNOW who signed a cooperation agreement with the German network wab.



Large bearing test bench starts continuous operation

Fraunhofer´s test bench for rotor blade bearings of up to 6.5 meters in diameter has been successfully commissioned at the institute’s Hamburg facility, paving the way for automated continuous operation. A bearing can be validated on the test bench long before it is installed in a wind turbine. The aim is to lower development costs and reduce yield loss.



Better Protection for Power Converters

Gaining a better understanding of power converter failure is vital in order to develop more effective protective measures and thus improve the profitability of turbine operation. For this purpose, field data from various sites and turbine types are being analyzed, damage models derived, and experimental tests performed on components.
