How does a wind turbine generate electricity simple?
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, which creates electricity.
What is the generator in a wind turbine?
Wind turbines commonly operate on a simple principle: instead of employing the electricity to create wind—such as a fan—wind turbines utilize the wind to produce the electricity. The wind rotates the propeller-like blades of a turbine within a rotor, which turns the generator to create electricity.
Do windmills generate AC or DC?
Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces DC electricity, which is then converted to AC via an inverter that can then be passed on to power your home.
Which type of generator is used in wind power generation?
The type of generator most used in wind turbines are the permanent magnet synchronous generators.
How does a turbine electric generator work?
In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft. The force of the fluid on the blades spins/rotates the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.
How does the generator work?
Electric generators work on the principle of electromagnetic induction. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.
What voltage do wind generators produce?
690 V
The turbine generator voltage is normally classed as ‘low’, in other words below 1,000 V, and is often 690 V. Some larger turbines use a higher generator voltage, around 3 kV, but this is not high enough for economical direct interconnection to other turbines.
How long can a wind turbine generate electricity?
20-25 years
Wind turbines can carry on generating electricity for 20-25 years. Over their lifetime they will be running continuously for as much as 120,000 hours. This compares with the design lifetime of a car engine, which is 4,000 to 6,000 hours.
What voltage does wind turbine generate?
The turbine generator voltage is normally classed as ‘low’, in other words below 1,000 V, and is often 690 V. Some larger turbines use a higher generator voltage, around 3 kV, but this is not high enough for economical direct interconnection to other turbines.
What’s an example of a generator?
In electricity generation, a generator is a device that converts motive power (mechanical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks.
