4 FAQs about [Wind power tower collapses]
Where do wind turbines collapse?
According to the results, 87% of the collapsed wind turbines collapsed when the wind speed was at least 60 m/s, and 81% of the collapses occurred between the foundation and one third of the height of the wind turbine tower. The above result reveals that the primary location of failure of a wind turbine tower is in the lower part of the tower.
How many wind turbine tower collapses are there?
These cases involved 68 wind turbine tower collapses that occurred in 11 countries on four continents. Fig. 3 shows that most wind turbine collapses by continent occurred in Asian countries (59%), and the second most occurred in North America (15%).
How to prevent wind turbine collapse?
Wind turbine collapse case analyses in Section 4 reveal that most locations of failure of wind turbines are in the middle-lower part of the tower. Therefore, tower bolts in these locations should be improved first. The strength or number of bolts can be increased to strengthen wind turbine towers. “Pitch system failure” had a medium risk level.
Why did the wind turbine tower collapse during Typhoon Soudelor?
During typhoon Soudelor, the collapse of one turbine tower involved a tower-blade collision which dented the wind turbine tower. Despite the fact that the wind turbine tower did not collapse, it had to be demolished for reasons of security.
