A 3-phase, Y-connected synchronous generator has a direct-axis synchronous reactance of 159 and a quadrature-axis synchronous reactance of 109. The alternator supplies current of 15A at a phase angle of 45 lagging and a phase voltage of 380V. Assuming that Ra is negligible, Calculate a) The load angle, b) The components of armature current Iad and Iaq. c) The no-load voltage and percentage regulation, d) The power delivered from the alternator, e) The maximum power that the alternator can deliver.
