Problem #2 | Impedance & Reactance diagram | PSA

2.Draw an Impedance & Reactance diagram for the electric power system shown in figure showing all the impedances in per unit on a 100MVA base. Choose 20KV as the voltage base for the generator 1.The three- phase and line- to- line ratings are given below
G1 :90 MVA, 20 KV , X = 9%
T1: 80 MVA, 20/200 KV, X=13%
T2: 80 MVA, 200/20 KV, X=18%
G2 : 90 MVA, 17 KV, X= 8%
Load: 200Kv , S=48MW+j64MVAr
Line : 200 KV, X=120 Ω

Very nice very easy explanation and plz explain about load flow study

[Crazymorality]

Mam I refferred base value formula of yours but still im not getting same base value as in my reference book 😭. ... Please help😢
