A 50 Hz, 4-pole turbo generator is rated 500 MVA, 22 kV and has an inertia constant (H) of 7.5. Assume that the generator is synchronized with a large power system and has a zero accelerating power while delivering a power of 450 MW. Suddenly its input power is changed to 475 MW. Find the speed of the generator in rpm at the end of a period of 10 cycles. The rotational losses are assumed to be zero.

Question
A 50 Hz, 4-pole turbo generator is rated 500 MVA, 22 kV and has an inertia
constant (H) of 7.5. Assume that the generator is synchronized with a large power
system and has a zero accelerating power while delivering a power of 450 MW.
Suddenly its input power is changed to 475 MW. Find the speed of the generator in
rpm at the end of a period of 10 cycles. The rotational losses are assumed to be zero.
