A two-pole, 60-Hz synchronous generator has a rating of 200 MVA, 0.85 power factor lagging. The kinetic energy of the machine at synchronous speed is 1180 MJ. The machine is running steadily at synchronous speed and delivering 50 MW to a load at a power angle of 8 electrical degrees. The load is suddenly removed. Determine the acceleration of the rotor. If the acceleration computed for the generator is constant for a period of 12 cycles, determine the value of the power angle and the rpm at the end of this time.
