I want to reduce 3-phase fault MVA at 33kV Wind farm substation. I tried for split bus arrangement, but still the Fault MVA is not in recommended range. Can anybody suggest me how to model a current limiting reactor in PSS/E for this purpose?

A "current limiting" reactor is still a reactor, modeled in steady state with its reactance in series with the branch connected to. Start with an initial value (10% of X of branch connected to),perform a short-circuit study and move it up or down until the allowed fault MVA is achieved.
