1 j 0.1 2 G G j 0.1 j 0.1 Xg1 = 3 0.15 Xg2 = j 0.075 3 3 A three-bus power system is shown above. The p.u. impedances are on a base of 50 MVA and 12 kV. A three-phase symmetrical short circuit occurs at bus 3 with no fault impedance. Using Z-bus matrix method and ignoring pre-fault loading conditions: a) Compute the short-circuit current (20) b) Bus voltages during fault (5) c) Contributions of generators to the short-circuit current (5)
