solve D and E.
![A 15-kV 35-KVA 0.76-PF-lagging 50-Hz four-pole Y-connected steam-turbine
generator has a synchronous reactance of 3.50 0 per phase and an armature
resistance of 0.75 0 per phase. This generator is operating in parallel with a
large power system (infinite bus).
a) What is the magnitude of E, at rated conditions?
b) What is the generator's torque angle at rated conditions?
c) If the field current is constant, what is the maximum power
possible out of this generator? How much reserve power or
torque does this generator have at full load?
d) Sketch the corresponding phasor diagram and calculate for the
armature current (assume the field current is still unchanged)
