The one-line diagram of a simple four-bus power system is
shown in the Figure. Each generator is represented by an emf
behind the transient reactance. All impedances are expressed in
per unit on a common MVA base. All resistances and shunt
capacitances are neglected. The generators are operating on no
load at their rated voltage with their emfs in phase. A bolted
three-phase fault occurs at bus 4.
(a) Using reduction method obtain the impedance to the point
of fault and the fault current in per unit.
