Longitudinal and transverse reactances of 50 MVA, 13.5 KV, 50 Hz, star connected salient pole synchronous generator are Xd = 1.5 ohms / phase and Xq = 1.25 ohms / phase. When working at full load of this generator, power factor is 0.85 (end). Find the power (MVA) produced by this generator whose stator resistance Rs is neglected?
