Q. No. 01 [CLO1-C3]: Draw an impedance diagram for the electric power system shown in Figure-1, showing all impedances in per unit on a 100-MVA base. Choose 20 kV as the voltage base for generator. The three-phase power and line-line ratings are given below: G : T : T2 : G2 : Line: X = 9% 80 MVA 20/200 kV X = 16% 80 MVA 200/20 kV X = 20% X = 9% X = 120 2 90 MVA 20 kV 90 MVA 18 kV 200 kV Load: 200 kV S = 48 MW +j64 Mvar T T2 2 Line G1 G2 Load
