A 1GW synchronous generator is connected to an infinite bus through a transmission line. The synchronous reactance of the generator is 9Ω and the inductive reactance of the transmission line is 3Ω. The infinite bus voltage is 110kV. If the generator delivers its rated power at unity power factor to the infinite bus, compute the following:
a. Terminal voltage of the generator
b. Equivalent field voltage
c. Real power output at the generator terminals
d. Reactive power output at the generator terminals
