V. Draw the pu impedance diagram of the power system shown. Use a base value 50 MVA, 138 KV in the 40 2 transmission line. The ratings of the generators, motors, and transformers are: Generator 1 Generator 2 Synchronous motor 3 Three-phase Y-Y transformers Three-phase A-Y transformers 20 MVA, 13.2 kV, Xs = 15% 20 MVA, 13.2 kV, Xs = 15% 30 MVA, 6.9 kV, Xs = 20% 20MVA, 13.8/ 138 kV, X=10% 15MVA, 6.9/138 kV, X=10% All the transformers are connected to step up the voltages of the machines to the transmission line voltage.
