SOLVED: Please answer clearly, answer only if you know the answer perfectly.Draw the per unit impedance diagram for the power system shown in the figure. Use a base of 100 MVA, 220 kV in 50 Ω line. The ratings of the generator, transformer, and motor are: Generator: 40 MVA, 33 kV, X = 20% Transformer: 40 MVA, 33/220 kV, X = 15% Motor: 30 MVA, 220/11 kV, X = 15% Static load: 80 MW, 30 MVAr, 11 kV.
