Default 3phase /2okw generator AVR circuit diagram

I have a 3phase/20kw AC generator with( kirloskar 3piston air cooled engine) booster/transformer controlled voltage regulator. I want update with electronic automatic voltage regulator(AVR), so please provide me circuit diagram for AVR to build myself.

your current sensing inductor type regulator is likely as good as any you can build. [if the speed is correct and steady]
no voltage regulation will work well if the speed is not well governed !!!
there are inexpensive aftermarket modern regulators
for example

but if you just want to experiment use a regulated DC supply bucked down by an unregulated DC supply to control the field.
the experimental part is finding the right proportions for these voltages, and controlling the larger current to the field.

PS we might reinvent the wheel while we are at it.
PPS use all necessary precaution as lethal voltages will be present !!!
