Question

3) A three-phase, nozzle, 4-pole cylindrical pole synchronous generator feeds a 400 Volt, 50Hz conversion center. The synchronous reactance of the synchronous generator is 0.72 Ove armature resistance is neglected. The relation between the pole voltage E 'induced in the induction of the synchronous generator and the excitation current, is selected as E, = 824. In this working environment of the synchronous generator,

a.) On the consumer screen, find the excitation current (U), load values, internal phase values, the moment induced in the generator (M.), to provide 54 kW active power, 40kVAr inductive reactive power.

b.) Synchronous generator provides 54 kW active power while its constant losses are 6.48 kW and the excitation circuit losses are neglected.
