Transient Stability
A 60 Hz, 100 MVA, 4-pole generator has an inertia constant of 5 seconds
(a) What is synchronous speed of the generator?
= 1800 rpm
(b) What is the kinetic energy of the rotor at synchronous speed?
Kinetic Energy = MVA Rating × H
= 100 MVA × 5 s
= 500 MJ
(c) What is the moment of inertia of the rotor?
