    i am currently doing project on Generator voltage control system.
    Could you send me circuit diagram for automatic voltage regulator that
    will give output voltage of 220V/50hz AC.

    You have a lot to learn, and not just about electronics. Like how to
    communicate.
    Care to give it another try?

    How about this:

    He may need the isolated version:

    If you take the knob off a variac, you can fit it with a pulley. A
    small gear motor can then turn the variac up and down. A meter-relay
    and a power relay can then control the power to the motor.

    Generator? You're using a DC generator instead of an
    alternator? If it isn't a permanent magnet type, you'd
    just trim the output voltage by modulating the field coil current.

    To make it AC, there's lots of designs out there: look into
    into "variable frequency controls" that drive AC motors,
    for examples, or "power inverter" like provide AC in
    automobiles if your needs are low-power.
