All you need to do is rectify the AC to provide DC to the field and design an amplifier that will operate with a voltage reference to regulate the field current. Look up automotive alternator regulator, it is the same thing.

field controler dc voltage this voltage field 10 v dc 440v
diesel 1800rpm 60 hz
and 120 voltage referance voltage have
 
You need to desin a circuit to monitor the output voltage and increase the field if it drops too low and increases it if it's too high. I don't know that much about this looking at an automotive alternator would be a good start.
 
Hello,

I am not discouraging you to built your own AVR or Generator Field Exciter however, if it involves high KVA Generator,its better and safer not to work with this expensive and dangerous experiment, there is a lot of variables involve in such design,it may take 1 man-year to built it! ,however if you really want to, I can send you an old copy of sample design from my collection.

Cheers!

Hi,

My name is Sude. I am looking for AVR schematic for a AC alternator and came across your above post. I would really appreciate if you would be kind enough to send me a copy of your sample design. The specs of the alternator are as follows.

1) 100 KVA, 410 volts 50 Hz
2) Exciter voltage 6.78 volts for 410 volts out put with no load.
3) Exciter current around 750 ma

Many thanks.

Sude
