Note 4: The site data below was not chosen as being particularly suitable for wind turbines, but was taken directly from the anemometer locations used in the European Wind Atlas. In the case of e.g. Frankfurt (D), one may e.g. find locations on neighbouring hills with twice as high an annual production as you would get at the airport where the ...

Wind Turbine Generators

http://www.xn--drmstrre-64ad.dk/wp-content/wind/miller/windpower%20web/en/tour/wtrb/electric.htm

On large wind turbines (above 100-150 kW) the voltage (tension) generated by the turbine is usually 690 V three-phase alternating current (AC). The current is subsequently sent through a transformer next to the wind turbine (or inside the tower) to raise the voltage to somewhere between 10,000 and 30,000 volts, depending on the standard in the ...

Wind Turbine Generators

http://ele.aut.ac.ir/~wind/en/tour/wtrb/electric.htm

Wind turbines may be designed with either synchronous or asynchronous generators, and with various forms of direct or indirect grid connection of the generator. Direct grid connection mean that the generator is connected directly to the (usually 3-phase) alternating current grid.

Pitch Controlled Wind Turbines On a pitch controlled wind turbine the turbine's electronic controller checks the power output of the turbine several times per second. When the power output becomes too high, it sends an order to the blade pitch mechanism which immediately pitches (turns) the rotor blades slightly out of the wind.

http://www.xn--drmstrre-64ad.dk/wp-content/wind/miller/windpower%20web/en/tour/wtrb/syncgen.htm

Wind turbines which use synchronous generators normally use electromagnets in the rotor which are fed by direct current from the electrical grid. Since the grid supplies alternating current, they first have to convert alternating current to direct current before sending it into the coil windings around the electromagnets in the rotor.

Variable Slip Generators for Wind Turbines

http://ele.aut.ac.ir/~wind/en/tour/wtrb/varislip.htm

Manufacturers of electric motors have for many years been faced with the problem that their motors can only run at certain almost fixed speeds determined by the number of poles in the motor. As we learned on the previous page, the motor (or generator) slip in an asynchronous (induction) machine is usually very small for reasons of efficiency, so the rotational speed will vary with around 1 per ...

Generatorer til vindmøller

generatorer er noget usædvanlige i forhold til andre generatorer, der er tilsluttet elnettet. En af grundene er, at denne generatortype er tilpasset en effektkilde (vindmøllens rotor), som leverer meget varierende mekanisk effekt (moment).
