PowerWorld Simulator case Problem 11.26 duplicates Example 11.10, except with the synchronous generator initially supplying \(100 \mathrm{MW}\) at unity power factor to the infinite bus.

(a) Derive the initial values for \(\delta, E_{q}^{\prime}, E_{d}^{\prime}\) and \(E_{f d}\).

(b) Determine the critical clearing time for the Example 11.10 fault.
