Can anyone give me the solution using the MVA method for this problem?!?!?
Quick description if you don't have the book:
A generating unit is shown in the figure. The 3 phase, short-circuit MVA contribution of G1 for a 230 kV bus is most nearly: Answer is 2290
figure layed out as G1-------------T1 (xfmr)---------(230 kv Bus)------Load
G1: 3phase, 834 MVA, 22 kV, X'd = 23%, 0.85 lagging
T1: 3phase, 933 MVA, 22/230 kV, Z = 15%, Delta/GRD-WYE
