The Fig P11 is a one line diagram of a simple power system There prefault system is on no load with 1 0 pu voltage and prefault currents are zero

The Fig. P1.1 is a one-line diagram of a simple power system. There prefault system is on no-load with 1.0 pu voltage and prefault currents are zero. A BOLTED THREE-PHASE FAULT occurs at point P. (a) Draw the pre-fault single-phase equivalent circuit showing numerical values. (b) (i) Calculate the subtransient current in the fault (ii) Calculate the voltages at the busses during the fault. (iii)Calculate the e subtransient current in the lines. (c)) Determine the Zbus relating the bus currents and voltages (i) Calculate (b)(i)-(iii) using the Zbus method. 0.15 pu Xd = 0.1 pu Ti G2 G1 1/110 kV X,d = 0.05 pu sh 110 / 11 kV Fault X"0.5 pu
