Answer»

A power system shown below has following specifications of components:

G1: 22 kV, 20 MVA, X = 5%

G2: 22 kV, 20 MVA, X= 5%

T1: 22 kV/100 kV, 18 MVA, X = 10%

T2= 100 kV/22kV, 18 MVA, X = 10%

Txline:= 110 kV, X = 90 Ω







If the base voltage of 22 kV of G1 as is taken as base voltage and 40 MVA as base MVA, the corresponding impedance diagram will be(in pu).
