Question

In the shown below power system, both generators G1 and G2 emf’s are equal.
All the system data are shown on the system diagram.
a) Draw the system diagram in per unit using (MVA)base = 75 and (KV)base =
20 KV in the generators side.
b) Calculate the three-phase balanced short circuit current (If) at busbar 3 in
Ampere and the fault level (MVA)sc in MVA.
c) If the fault at busbar 3 is a line-to-line fault, calculate the fault current in
Ampere and the fault level (MVA)sc in MVA.

In the shown below power system, both generators G1 and G2 emf°s are equal. All the system data are shown on the system diagram. a) Draw the system diagram in per unit using (MVA)base = 75 and (KV)base 20 KV in the generators side. b) Calculate the three-phase balanced short circuit current (It) at busbar 3 in Ampere and the fault level (MVA)sc in MVA. c) If the fault at busbar 3 is a line-to-line fault, calculate the fault current in Ampere and the fault level (MVA)sc in MVA. 1 3 Tr. 1 Xs = j0.2 p.u.
