A generator feeds power to an infinite bus through a double circuit transmission line. A 3 phase fault occurs at the middle point of one of the lines. The infinite bus voltage is 1 pu, the transient internal voltage of the generator is 1.1 pu and the equivalent transfer admittance during fault is 0.8 p.u. The 100 MVA generator has an inertia constant of 5mJ/MVA and it was delivering 1.0 p.u. power prior of the fault with rotor power angle of 30°. The system frequency is 50 Hz.

a syn A: A sylienfonotus generator of 100 MVA, 22 kV, and 0.25 pu transient reactance supplies a motor of 50 MVA, 22 kV, and 0.2 pu transient reactance. The motor is drawing 40 MW at 0.8 power factor leading and terminal voltage of 21.9 kV. The line connecting them has a reactance of 0.05 pu on a base of 100 MVA. Find the transient currents in the generator, the motor, and the fault when a 3-ph fault occurs at the motor terminals. Take SB = 100 MVA, VB = 22 kV, and use the internal voltages %3D %3D of the machines method.
