For those who are eager to learn, an explanation is given below.Wind is formed by the indirect effect of the sun on the Earth’s surface. There is a reasonable explanation why is it so. As the sun shines, the Sun heats the Earth's surface; the air near ground level gets hot and rises up. Cold air at higher altitudes replaces it.

Wind turbine cut-out speed means, the highest predicted wind speed at which an operating wind turbine stops producing power due to excess wind. The cut-out wind speed is designed to apply the breaking system to slow down or stop the turbine from spinning and protect your equipment from damage.

Variable speed drives in modern wind turbines are used to maximize wind turbine efficiency when the turbine is running below rated power and to reduce loading on the drive-train.
In addition, there is something called a pitch control of the blades which is usually used to limit the energy captured when the turbine is operation above rated wind speed.
