Question

A generator is connected through a transformer to a synchronous motor. reduced to the same base, the per-unit subtransient reactances of t h e generator and motor are 0.15 and 0.35, respectively,and the leakage reactance of the transformer is 0.10 per unit . a three-phase fault occurs at the terminals of the motor when the terminal voltage of the generator is 0.9 per unit and the output current of the generator is 1.0 per unit at 0.8 power factor leading. find the subtransient current in per unit in the fault, in the generator, and in the motor. use the terminal voltage of the generator as the reference phasor and obtain the solution (a) by computing the voltages behind subtransient reactance in the generator and motor and (b) by using thevenin 's theorem. observed the real component of fault current.
