The one-line diagram of a simple three-
bus power system is shown below. Each
generator is represented by an emf behind
the transient reactance. All impedances
are expressed in per unit on a common
100 MVA base. Determine the fault
current during a fault when a balanced
three-phase fault occurs on Bus 1. Use the
Thevenin Theorem approach.
