A 450 MVA, 26-kV generator is connected to a 345-kV power system through a 500MVA, 26-kV:345-kV transformer which can be represented by a series reactance of 95 m Ω when referred to its low-voltage terminals. The generator has a saturated synchronous reactance of 1.73 per unit and a rated-open- circuit-voltage field current of 2140 A. Under normal operating procedures, the generator is operated under automatic voltage regulation set to maintain its terminal voltage at 26 kV. In this problem you...
