The one-line diagram of a three-bus power system is shown in
Figure 4. All impedances are
expressed in per unit on a common MVA base. All resistances and
shunt capacitances are
neglected. Information on each component in this system is given
below:
• Each generator is represented by an emf
behind the sub-transient reactance of j0.045
and their neutrals are connected to the
ground.
• Line 1-2 has reactance of j0.88
