A 100-MVA, 20-kV synchronous generator is connected through a transmis- sion line

A 100-MVA, 20-kV synchronous generator is connected through a transmis- sion line to a 100-MVA, 20-kV synchronous motor. The per unit transient reac- tances of the generator and motor are 0.25 and 0.20, respectively. The line reac- tance on the base of 100 MVA is 0.1 per unit. The motor is taking 50 MW at 0.8 power factor leading at a terminal voltage of 20 kV. A three-phase short circuit occurs at the generator terminals. Determine the transient currents in each of the two machines and in the short circuit.
