Question 2 | A 30 MVA, three-phase, wye-connected, 60 Hz, 13.8 kV synchronous alternator has negligible stator resistance and synchronous reactance of 10 2/phase. (a) Calculate the % voltage regulation of the alternator when it is operation in isolation (stand- alone) and delivering rated MVA to a 0.866 pf leading load at 13.8 kV. Q %VR (b) Calculate the % voltage regulation of the alternator when it is operation in isolation (stand- alone) and delivering rated MVA to a 0.707 pflagging load at 13.8 kV. %VR
