field voltage will be maximum of DC generator & current can be calculated from ohms law by finding the ressistance. The AVR should be 1.6 times more in voltgae & current than the calculated value
hi
you informed as below
For the start:
I3ph-fault=Inom gen/X"d (for the turbogenerator from 13%-17%).
but i have still one doubt i,e I nom gen (or) V nom gen.
Thank you for your reply,
For 30MW 11KV Generator, rated current is 1968, Xd"(sat)-11.84% & Xd"(unsat)-14.79. i have to take saturation value or unsaturation value of Xd".
