Solve this queation
The generator in Figure 11.4 is initially operating in
the steady-state condition given in Problem 11.8
when a three-phase-to-ground bolted short circuit
occurs at bus 3. Determine an equation for the
electrical power delivered by the generator versus
power angle ō during the fault.
Problem 11.8
The synchronous generator in Figure 11.4 delivers 0.8
per-unit real power at 1.05 perunit terminal voltage.
Determine: (a) the reactive power output of the
generator; (b) the generator internal voltage; and
(c) an equation for the electrical power delivered by
the generator versus power angle d.
