Two 300 MVA, 22 kV, 3-phase, 60 Hz alternators are connected by a tran...
Given that base MVA is the rating of T1
Rating of single phase transformer of 3-phase transformer bank = 12 MVA
Rating of 3-phase transformer bank = 3 × 120 = 360 MVA
It is connected in Δ Y connection.
Primary voltage of three phase transformer bank = Primary voltage of single phase transformer = 22 kV
Secondary voltage of three phase transformer bank = √3 × secondary voltage of single phase transformer = √3 × 127kV = 220kV
XT1 (for single phase transformer) = j0.08
XT1 = (for three phase transformer)
XT1 = j0.08 pu
XT2 (old) = j0.10
= j 0.12 pu
Given that, reactance of transmission line (XL) = 81Ω
As the generator reactance values are not given, let assume zero sequence reactance of generator 1 and generator 2 are Xg1 and Xg2 respectively.
Now, the zero-sequence network becomes.
