GATE Electrical Engineering (EE) 2011 Solved Paper

Two generator units G₁ and G₂ are connected by 15kV line with a bus at the mid-point as shown below

G₁ = 250 MVA, 15 kV, positive sequence reactance X_G1 = 25% on its own base
G₂ = 100 MVA, 15 kV, positive sequence reactance X_G2 = 10% on its own base L₁ and L₂ = 10 km, positive sequence reactance X_L = 0.225 Ω/km
For the above system, the positive sequence diagram with the p.u values on the 100 MVA common base
