The wind gets stronger after the wind turbine stops

What happens if wind speed increases?

If the wind speed continues to increase, all wind turbines have a maximum wind speed above which they cannot operate. This is called the turbine's 'furling speed'. If the wind speed exceeds the furling speed (for example in a hurricane) the turbine has to be shut down to prevent the blades getting damaged.

Why would a wind turbine stop if there is no wind?

The most obvious reason that a wind turbine would stop is that there is no wind to blow on it. If there is no wind, the turbine cannot rotate. Meteorologists (weather scientists) measure wind speed in knots, which are almost the same as miles per hour (1 knot = 1.15 mph) 1. Wind speed is sometimes also measured in meters per second.

How fast can a wind turbine run?

Wind Speed too High – Furling Speed As wind speed increases, the wind turbine will reach what is called its 'rated speed'. This is the wind speed at which the turbine generates maximum electricity, and for a modern grid-scale wind turbine, this is about 25mph 4 (Beaufort Wind Force 6 – Strong Breeze).

Why do wind turbines shut down?

The connection speed is generally from 3 m/s (19.8 km/hr). This is the speed at which electricity starts to be generated. Another reason for shutting down a wind turbine is to undertake preventive or corrective maintenance. The former involves scheduled shutdowns to inspect all the components.
