How Do Wind Turbines Work? | Department of Energy

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator,

6 FAQs about [The role of the turbine shaft of a wind turbine]

How does a wind turbine work?

Rotor: harvests the wind's energy usually with 3 blades connected to a shaft. When the wind blows, the rotor rotates, harnessing the kinetic energy from the wind. The Nacelle or Gondola, a structure located at the top of the wind turbine, houses the electronic and mechanical system necessary for transforming wind energy into electricity.

How do wind turbine blades work?

Wind turbine blades provide a lift force, similar to an air-plane, which creates a torque on the main shaft. As wind passes over the blades, this force makes the shaft rotate. If there was no energy extracted from the system via the electrical generator, and the entire system were lossless, the turbine shaft would accelerate indefinitely.

What is a hub in a wind turbine?

2. Hub The hub of a wind turbine is the component responsible for connecting the blades to the shaft that transmits motion to the gearbox in the case of a Doubly Fed Induction Generator (DFIG) or to the generator shaft in the case of a Direct-Drive Permanent Magnet Synchronous Generator (PMSG).

How do turbine rotors work?

Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift.

How does a wind turbine turn mechanical power into electricity?

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.

Why do wind turbine blades feather?

The pitch system can also "feather" the blades, adjusting their angle so they do not produce force that would cause the rotor to spin. Feathering the blades slows the turbine's rotor to prevent damage to the machine when wind speeds are too high for safe operation.
