    how is it possible to generate electricity using wind power generator,the wind will not be constant for every minute it changes but we need to maintain a constant frequency to connect it to grid if anybody have an idea post it

    :D You have a lot up your sleeve man!....... anyways, coming to the point. There are power electronic circuits (inverters with microprocessors also cycloconverters) available which maintain constant voltage & frequency at the output of wind turbine inspite of varying wind conditions.

    Other method is to use wind generators to just charge the back-up batteries of inverters & not to supply normal AC power to load. The inverter than supplies normal AC power to connected load from the charged batteries!

    For further info you can google on the same....... all the best ;)

    The current methodology is to rectify the alternator output and use a device called a synchronous inverter to produce AC locked to the line frequency.
