The generating unit in Problem 11.1 is initially operating at Pmp.u. = Pep.u. Pep.u. = 0.7 per unit, w = Wsyn, and 8 = 12° when a fault reduces the generator electrical power output by 60%. Determine the power angle five cycles after the fault commences. Assume that the accelerating power remains constant during the fault. Also assume that wp.u. (t) = 1.0 in the swing equation.
