Consider the single-line diagram of a power system shown in the figure with equipment rating as follows; Generator G1: 50 MVA, 13.2 kV, x = 0.15 pu Generator G2: 20 MVA, 13.8 kV, x = 0.15 pu Three-phase ∆-Y transformer T1: 80 MVA, 13.2∆/16YkV, X = 0.1 pu Three-phase Y-∆ transformer T2: 40 MVA, 165Y/13.8∆kV, X = 0.1 pu Load: 40 MVA, 0.8 PF lagging, operating at 150 kV Choose a base of 100 MVA for the system and 132 kV base in the transmission-line circuit. Let the load be modeled as a parallel combination of resistance and inductance. Neglect transformer phase shifts. Draw a per-phase equivalent circuit of the system showing all impedances in per-unit.
