Q4 / Equipment ratings for the four - bus power system shown in Figure are given as follows: TI 73 60 500 Generator GI: 500 MVA, 13.8 KV. X = X2 = 0.20. Xo = 0.10 per unit Generator G2: 750 MVA, 18 KV. X = X2 = 0.18, Xo = 0,09 per unit Generator G3: 1000 MVA, 20 kV, X = 0.17. Xz = 0.20.Xo = 0.09 per unit Transformer Ti: 500 MVA, 13.8 kV A / S00 kV Y. X = 0.12 per unit Transformer T2: 750 MVA, 18 LV A / 500 kV Y, X = 0.10 per unit Transformer T3: 1000 MVA, 20 kV A / 500 kV Y. X = 0.10 per unit each line: X = 50 ohms, X, = 150 ohms 77 The inductor connected to generator G3 neutral has a reactance of 0.028 pu.
