How strong is the wind before wind turbines need to be shut down
Anything in excess of 25 m/s (90 km/hr) is dangerous for the wind turbine so it opts to shut down. The connection speed is generally from 3 m/s (19. We will explain everything you should know. You are not the first person to ask why you have sometimes seen a number of wind turbines stopped and you will not be the last. As the wind speed continues to increase, the power generated by the turbine remains constant until it eventually hits a cut-out speed (varies by turbine) and shuts down to prevent unnecessary strain on the rotor.
