Q2) A simple three-phase power system is shown in the Figure 1. Assume that the ratings of the various devices in this system are as follows: Generator G1 : 100 MVA, 13.8 kV, X,=X, = 0.2 pu, Xo=0.25 pu, Xn=0.05 pu. Generator G2 : 100 MVA, 20.0 kV, X,=X2 = 0.25 pu, Xo=0.25 pu, Xn=0.05 pu. Transformer T1 : 100 MVA, 13.8/138 kV, X = 0.10 pu. Transformer T2 : 100 MVA, 20.0/138 kV, X = 0.15 pu. Each Line: X=X == 40 Q, X,=100 N.
