Power factor of wind power generation system.

jcm
At an oil storage depot with a standard engine driven three phase generator

some time ago had to investigate why generator failed,stored energy electrical and electronic parts damaged. The conclusion was that the old chunky power factor Hand/Off/Auto switch someone had switched it to hand; the generator did not like this stored energy  on start up (generator exciter diodes blown and other electronics damaged). What I am asking only out of interest could the same thing ever happen if the supply was solely fed by wind powered generator?  Not really talking about wind farm supply as this would be like mains supply and would need standard PF correction at the user end because of changing current and voltage values.


 Oil or gas engine driven three phase generators have inbuilt PF and don’t need existing PF correction I don't know about small scale wind power . Looking up some information on the web, As written on the web site below Seems a bit completed with Self turned fuzzy logic controller (whatever that is) and Power factor improvement of wind power generation system through control of grid side converter.

Any engineer has a knowledge  of the requirements for PF with wind supply at the consumer end. only out interest thank you.

Thanks jcm


This is a good site for types of wind generators.

    There is a possible source of confusion here, Some inverter designs can be programmed to effectively provide a complex source impedance when feeding into a stiffer supply , such as a solar panel driving the grid -  by pushing more current at one or other of the flanks of the sinewave than at the peak . This looks like the generation of reactive power, and can be very useful for grid stabilisation. This is sometimes expressed as an equivalent power factor, being a phase shift between I and V.
