The type of generator most used in wind turbines are the permanent magnet synchronous generators.
Does a wind turbine generate AC or DC?
The electrical generators used on wind turbines may either be induction generators or synchronous generators. The electrical power from the generator is typical 60 Hz, AC power with 600V output for large wind turbines.
Does a wind turbine have a generator?
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
How many volts does a wind turbine produce?
On large wind turbines (above 100-150 kW) the voltage (tension) generated by the turbine is usually 690 V three-phase alternating current (AC).
How much voltage does a small wind turbine produce?
The smallest production wind turbines have a rotor diameter of 1 m and only produce enough power to charge a few 12 volt batteries : about 100 watts.
How do wind turbines work when it not windy?
If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity. The turbine starts to create power at what is known as the cut-in speed.
How big is a small wind turbine?
Small wind turbines used in residential applications typically range in size from 400 watts to 20 kilowatts, depending on the amount of electricity you want to generate. A typical home uses approximately 10,932 kilowatt-hours of electricity per year (about 911 kilowatt-hours per month).
At what range of RPM does a typical wind turbine generator rotate?
The turbine blades lift and rotate when the wind blows over them. The blades turn a low-speed shaft at about 30-60 rotations per minute (rpm). A gear box connects the low-speed shaft to the high-speed shaft and increases the rotational speeds from about 30-60 rpm to about 1,000-1,800 rpm.
