Question

A 3-phase, 50MVA, 32-KV, 0.85-PF- lagging, 50-Hz, 4-pole, Y-connected steam-turbine generator has a synchronous reactance of 10 per- phase, and a negligible armature resistance. This generator is connected to operate in parallel with a large power system (infinite bus). If the armature current lA = 1200 Amperes at 0.8 leading power factor, Calculate the reactive power, state whether it is absorbed or supplied by the generator. Select one: O a. Q = 53.2 MVAR , Delivered O b. Q = 39.9 MVAR , Delivered O c. Q = 39.9 MVAR , Absorbed O d. Q = 26.35 MVAR, Absorbed e. None
