Answer to Question #336451 in Electrical Engineering for rein

Question

A 100 KVA. 4600 V three phase wye-connected alternator has an

armature resistance of 2 Ω per phase and synchronous armature

reactance, Xs’ of 20 Ω per phase. Find the full load generated voltage

per phase at: a)Unity power factor b) A power factor of 0.75 lagging ii)

Repeat part i) to determine the generated voltage per phase at full load

with: a) A leading load of 0.75 power factor b) A leading load of 0.4

power factor.
