Determine the regulation of three-phase, Electrical Engineering

Assignment Help:

A three-phase, six-pole, wye-connected synchronous generator is rated at 550 V and has a synchronous reactance Xs = 2 . When the generator supplies 50 kVA at rated voltage and a power factor of 0.95 lagging, ?nd the armature current Ia and the excitation voltage Ef . Sketch the phasor diagram of ¯ Vt , ¯ Ia, and ¯ Ef . Also, determine the regulation corresponding to the operating conditions.
