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 \(\delta\) during the fault.

Problem 11.8

The synchronous generator in Figure 11.4 delivers 0.8 per-unit real power at 1.05 per-unit 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 \(\delta\).
