A three-phase wye-connected synchronous generator is rated at 1000 kVA, 11 kV. This machine has an armature resistance, R_a
of 0.35O/phase, and a synchronous reactance, X_s
of 1.2O/phase. The field circuit has a DC voltage of 200 V and the maximum field current, I_f
= 10 A. The resistance of the field circuit is adjustable over the range from 20 to 200 ?.
