How a Wind Turbine Works

OverviewOther controlsAerodynamicsPower controlTurbine sizeNacelleBladesTower

Modern large wind turbines operate at variable speeds. When wind speed falls below the turbine''s rated speed, generator torque is used to control the rotor speed to capture as much power as possible. The most power is captured when the tip speed ratio is held constant at its optimum value (typically between 6 and 7). This means that rotor speed increases proportional to wind speed. The diff

How Wind Works

A modern turbine includes a series of blades mounted around a rotor to catch the wind and translate its kinetic energy into rotational energy. Our designs allow blades to capture the full

What happens if a wind mill rotates in opposite direction?

Also, the wind direction cannot spin the blades backwards. That would be a pretty poor windmill design The design of windmills is such that they rotate to face the wind and have sails or

Can Wind Turbines Rotate in Both Directions? – Climate Cafes

If the wind changes direction, the nacelle of the wind turbine is rotated to face the new wind direction by the yaw motor. This is an important distinction to make because it

How Wind Power Works

The two primary aerodynamic forces at work in wind-turbine rotors are lift, which acts perpendicular to the direction of wind flow; and drag, which acts parallel to the direction of wind flow. Turbine blades are shaped a lot like airplane wings -
