A wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can then convert this mechanical power into electricity.
Most wind turbines operating commercially today in Ireland consist of 3 rotor blades that rotate around a horizontal hub. The blades face into the wind and rotate as the wind passes through them. The rotor is connected to a nacelle (a housing for the generator and other electrical equipment) that is located at the top of a tower to ensure a higher and less interrupted wind flow.
Wind turbines start operating at approximately 4 – 5 metres per second reach a maximum output at 12 – 14 m/s and automatically shut down for safety at wind speeds greater than 25 m/s. The rotating motion is accelerated through the turbine transmission (which usually includes a gearbox although they are becoming less common) into the generator that converts the motion to electricity.
When more air passes through the blades, more electricity can be produced. The low voltage electricity from the generator is ‘stepped up’ through a transformer to match the national grid voltage. The electricity is transported from the wind turbine to the grid along electric cables which may be buried underground within the wind farm site. The electricity from the wind farm joins the national grid at a sub-station. Source: www.seai.ie
