Question

please show steps. Thank you.

(40%) Problem 2 of 3: An engine-generator set is paralleled with a 13.2 kv, 60 Hz infinite (utility) bus to deliver power to a 2000 kw plant load at 0.866 lagging power factor. The synchronous generator is wye-connected and rated 3750 kva, 13.2 kv, and 0.8 power factor lagging with 1.0 per unit synchronous reactance and negligible armature resistance. 13.2 kVI 60 Hz I infinite bus utility) rated: 3750 kva 0.8 lag load: 2000 kW at 0.866 lag (a) If the generator is operating at rated conditions, find the real and reactive powers supplied or (b) If the generator is operating at rated conditions, find the phase-to-neutral voltage induced in the (c) The field current is then lowered to reduce lEAl by 10%. Assuming that this reduction in field absorbed by the infinite bus. Be sure to append supplied or absorbed to each power quantity. armature winding by the field flux, EA, torque angle, 8, and armature current, IA, of the generator. current does not change the real power output of the generator, find the new values of torque angle, armature current, and reactive power supplied or absorbed by the infinite bus.
