Question details

Example 5 The single line diagram of a simple three bus power system is shown in Figure. The neutral of each generator is grounded through a current limitting reactor of 0.25/3 pu on 100 MVA base. The system data expressed in pu on a common 100 MVA base is tabulated below. All generators are running at their rated voltage and rated frequency with their emfs in phase. Shunt capacitances are neglected and the system is considered on no load Determine the fault current for a double line to ground fault at bus 3 through a fault impedance ZF0.1 pu Item Base MVA Voltage Rating X X 100 100 100 100 100 100 100 05 20 kV 0.15 0.15 0.05 20/220 kV 0.10 0.10 0.10 20/220 kV 0.10 0.10 0.10 220 kV 0.125 0.125 0.30 220 kV 0.15 0.15 0.35 kV 0.15 0.15 T2 L13 220 kV 0.25 0.25 0.7125
