TÜV SÜD has developed a computer model to demonstrate suitability for regions impacted by tropical storms based on the international IEC 61400 standard within the scope of type certification.
Using the international IEC 61400 standard as a basis, TÜV SÜD has developed a computer model enabling the impacts of such extreme wind situations on wind turbines to be simulated. The standard defines requirements for the use of wind turbines at specific sites, which are taken into account in ‘type approval’. To this end, the standard defines several wind classes. Edition 4 of the standard now introduces the new wind class T1 for tropical cyclones – also known as typhoons or hurricanes, depending on the region. The computer model enables the company to simulate even the most extreme wind conditions in regions impacted by tropical cyclones, and to use its simulation as a basis to verify whether a wind turbine is suitable for such regions. TÜV SÜD documents the suitability of a wind turbine for wind class T1 in the relevant type approval.
