A 60 Hz,4 Pole generator rated 150 MVA, 13.2 kV has an inertia constant of 15 MJ / MVA a. Find the stored energy in the rotor at synchronous speed b. If the input to the generator is suddenly raised to 60 MW for an electrical load of 50MW find the rotor acceleration. c. If the rotor acceleration calculated in part (b) is maintained for 12 cycles, find the change in torque angle and rotor speed in rpm at the end of this period.
