Q12:A 100|k VA, 1100 V, three-phase, 6-pole, Y-connected, 50 Hz synchronous machine has synchronous reactance of 6 0 per-phase and negligible armature resistance. Its core losses are 7 k W and its friction and windage losses are 8 kW. The speed droop is 2.5%. initially the machine is operated alone as a generator and the field current is adjusted such that the no-load voltage equals the rated voltage. a) If the prime mover of the machine is removed while the machine is connected to the infinite bus, and field flux of the machine is increased by27%. Find the power factor for the machine in this case.
