Determine the fault current and the bus voltages, Electrical Engineering

Assignment Help:

The one line diagram of a simple three-bus power system is shown in the figure 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, and for simplicity, resistances are neglected. The following assumptions are made:

  • Shunt capacitances are neglected and the system is considered on no-load.
  • All generators are running at their rated voltage and rated frequency with their emfs in phase.
