SOLVED: (a) Draw the impedance diagram in per unit for the system whose one-line diagram is shown in Figure below. Choose 100 MVA base and 13.8 kV as the voltage base for generator G1. The three-phase line-to-line ratings are as follows:TIT2Line 1Line 2Line 3000 000V074Generator G: 50 MVA, 13.8 kV, X=0.15 p.u. Generator G: 20 MVA, 14.4 kV, X=0.15 p.u.T: 60 MVA, 13.2-161 kV, X=0.10 p.u. T: 25 MVA, 13.2-161 kV, X=0.10 p.u. T: 25 MVA, 13.2-161 kV, X=0.10 p.u. Line 1: 20 j80 (actual) Line 2: 10
