Transcribed Image Text:Example 11.2
A 60-Hz synchronous generator having inertia constant H = 9.94 MJ/MVA and
a transient reactance X = 0.3 per unit is connected to an infinite bus through
a purely reactive circuit as shown in Figure 11.7. Reactances are marked on the
diagram on a common system base. The generator is delivering real power of 0.6
per unit, 0.8 power factor lagging to the infinite bus at a voltage of V = 1 per unit.
