A 3-phase, 450 V, 2-pole, 50 Hz, wye-connected, synchronous alternator. Xs = 1.62 ohm/phase. Connected to an infinite bus and supplies 120 kW with a power angle of 35 degrees.
Neglect losses and find:
a. turbine torque supplied to alternator.
b. excitation voltage.
c. active, reactive power and machine power factor.
d. neglecting saturation effects of the field, the excitation voltage
e. if the field current is reduced to 80% of its original value in part a.
f. the turbine speed for 60 Hz operation.
