Question 3 G1 G2 T1 Figure 5: Single Line Diagram Table 2: Equipment specification Base MVA Voltage kV X1(p.u) X2(p.u) Xo(p.u) 0.05 0.05 Item G1 G2 100 20 0.15 0.15 0.15 0.10 0.10 0.125 0.125 100 20 0.15 0.10 T1 100 20/220 0.10 T2 100 100 20/220 0.10 0.10 Line 1-2 220 0.30 Line 1-3 Line 3-2 220 100 100 0.15 0.15 0.35 220 0.25 0.25 VĀ + 0.1 A single line diagram is shown in Figure 5 with their specification shown in Table 2. The neutral reactance 0.25 per unit is connected to each generator neutral, and value of A is in the range of 0.1 0.9. Single line-to-ground fault occurs at bus 3 with a fault impedance ZF = j0.1 per unit. Evaluate the fault current at bus 3, fault voltage at bus 3 and bus 2, and line fault current between bus 3 and bus 2 in per-unit value.
