A 50 Hz, 500 MVA, 4-pole, 33 kV alternator has an inertia constant of 7.5 MJ/MVA. Compute:
(i) Stored energy at synchronous speed.
(ii) The rotor acceleration in mech degree/sec² if the input to the generator is suddenly raised to 400 MW for an electrical load of 350 MW.
(iii) The speed of rotor in rpm if the rotor acceleration is constant for 10 cycles.
