Question

For the single-line diagram in the image, convert the zero-, positive-, and negative-sequence reactance date to per-unit using the given base quantities. Use subtransient machine reactances.
Then, USE PowerWorld Simulator, create the generator, transmission line, and transformer input data files.
Next, run the Simulator to compute subtransient fault currents for (1) single line-to-ground, (2) line-to-line, and (3) double line-to-ground bolted faults at each bus. Assume 1.0 per unit prefault voltage and neglect prefault load currents and all losses. Note: L2 = 25 km
Show input data files (machine, transmission line and transformers), output data (fault currents, bus volatges and line currents), and screenshots of the Simulation.
