A 60 MVA, 69.3 KV, three-phase synchronous generator has a synchronous reactance Xs = 15 ohm/phase. The generator is supplying its rated power (i.e. 60 MVA) to an infinite bus at 0.8 power factor lagging. Determine: a) The armature current Ia. b) The generator emf per phase (E). c) The power angle. d) The maximum power (P) that the generator can supply. Xs = j 150 E la Vline = 69.3 KV
