A three-phase synchronous generator, rated at 50 MVA, 30 kV, and 60 Hz, has an armature
winding resistance of 0 Ω per phase and a synchronous reactance of 9 Ω per phase. The generator is
supplying its rated power at a 0.8 lagging power factor and rated voltage to an infinite bus.
Given this information, calculate the following:
a) The excitation voltage of the generator.
b) The power angle of the generator under these operating conditions.

4. In Problem 3, assume the generator's excitation is kept constant. Calculate the following:
a) The maximum steady-state power that the generator can deliver without losing synchronism.
b) The stator (armature) current at this condition
