Given a turbine-generator unit rated 100 MVA with a per unit inertia constant, H = 5 sec.

(a) Calculate the kinetic energy stored at synchronous speed (3600 rpm).

(b) Compare this figure with the kinetic energy of a 10-ton truck going at 60 mph.

(c) Suppose that the generator is delivering 100 MW and then, at t = 0, the line circuit breakers open. Calculate the shaft acceleration in rad/sec².

(d) At this rate, how long does it take for δ to increase from δ⁰ to δ⁰ + 2π radians?
