A synchronous generator is rated 1,300 MVA, 22,000 volt, three phase, 3600 rpm, 60 Hz with a synchronous reactance of 0.35 ohms per phase. The machine is delivering rated output at rated voltage and 0.94 power factor lagging.
a) Find real power output of the generator
b) Find reactive power
c) Find line current (output)
d) Find voltage behind synchronous reactance - per phase - assume wye
e) Find angle delta and draw the phasor diagram
f) If the generator efficiency is 95 percent, how many hp must the prime mover supply?
