GE Type ATB-2 Generators

[dwraith]

I am working on studies for an overseas client. He has 2 GE ATB-2 generators but no data and isn't happy with typical data.
Can anyone help me out with values for subtransient and transient reactances for actual machines, ratings 18824 kva and 21176 kva, 2 pole 13.8kV, 0.85 pf, 60 hz.
