The generator must operate at constant speed. How this is achieved when the wind speed is either too high or toolow. Essentially – If it is purely wind power after a generator can not keep running at a constant rate forever. However, a large flywheel rotation can retain sufficient energy to keep a current generator at a constant level for a maximum of five minutes or less. The windmill would get the flywheel at any rotation speed limit, speed gears would keep out more or less constant as the flywheel spins faster due to higher wind speeds, or slower due to decreased winds. The gear can be as simple as a basic transmission – they have these gears for bicycles are automatic, which change depending on the speed. There you go.

In wind farms around the blades are controlled by the computer and the blade pitch is variable. That way if the wind is 30 knots or 10 knots of leaves are adjusted to maintain the same speed.

With an automatic transmission, similar to the one in a car. . .

Hello Modern wind turbines control blade pitch. This would make the shaft speed approximately equal to different wind speeds.

The blade pitch is changed automatically to maintain the correct range of revolutions.
