A 2 GW synchronous generator is connected to an infinite bus through a transmission line. The infinite bus voltage (per phase) is 240kV (reference voltage), the inductive reactance of the transmission line is 6Ω, the synchronous reactance of the generator is Xs=9Ω. 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) The active and reactive power output at the generator terminals
d) The maximum generator real power limit (i.e., P max)
e) If a capacitor with capacitive reactance of 4Ω is connected in series with the transmission line, what is the new capacity of the system?
f) If a second transmission line with X
line 2=6Ω is connected in parallel with the original transmission line, what is the new system capacity?
