Draw the impedance diagram for the electric power system showingall impedances in per unit on a 90-MVA base.Choose 20-kV as the voltage base forgenerator.
Find the current of the G1 and G2 and the load current. Thethree-phase power and line-line ratings are given below. Show yoursolutions legibly and in details.
G₁ G₁: T₁: T₂: 90 MVA 80 MVA 80 MVA G₂: 90 MVA Line: Load: T₁ 38 20 kV 20/200 kV 200/20 kV 18 kV 200 kV 200 kV Load X = 14.440 X 16% X = 20% X : j 3.6 Ω X =j1200 S = 48 MW +j64 Mvar Line = = 2 T2₂ 38 G₂
