1. A 2500kVA, 6600V synchronous turbo alternator is operating at
full load and 0.8 pf lagging. This machine has a synchronous
reactance per phase is 10.4Ω and a negligible resistance. Compute
for the terminal voltage. Use two decimal
places.
2. A 3-phase, Y-connected, 6-pole, 60Hz generator has X S
=1Ω , negligible o rS (stator resistance), and Lsf = 0.2H . The
machine operates at a power angle of 31.48 with a field current of
100A. The line-to-neutral terminal voltage is 2400Vrms. Find the
line current. Magnitude only. Use 1 decimal
place
