A 50Hz 4 pole turbo- generator rated at 20 MVA,13.2 kV has inert ia constant of H = 9.0kW-sec/kVA. Determine the kinetic energy stored in the rotorat synchronous speed. Determine the acceleration if the input less the rotational losses is 25,000hp and the electric power developed is 15 MW. Ifthe acceleration computed for the generator is constant for a period of 15 cycles,determine the change in torque angle in that period and the r.p.m. at the end of15 cycles. Assume that the generator is synchronized with a large system and has no accelerating torque before the 15 cycle period begins.
