Problem2 A generator having H = 6.0 MJ /MVA is delivering power of 1 per unit to an infinite bus through a purely reactive network when the occurrence of a fault reduces the generator output power to zero. The maximum power that could be delivered is 2 .5 per unit. When the fault is cleared, the original network conditions again exist. Determine the critical clearing angle and critical clearing time.

A generator having H = 6.0 MJ /MVA is delivering power of 1 per unit to an infinite bus
through a purely reactive network when the occurrence of a fault reduces the generator
output power to zero. The maximum power that could be delivered is 2 .5 per unit. When
the fault is cleared, the original network conditions again exist.
Determine the critical clearing angle and critical clearing time.
