5 MW generator - typical reactances and time constants

[ters]

Looking for typical parameters, a small hydro machine, 5000 kVA, 450 rpm, 4.16 kV, pf 0.9, specifically some rough range for unsaturated reactances (pu): Xd, X'd, X"d, Xq, X1, X2 and X0 and open circuit time constants T'do, T"do, T'qo and T"qo. Thank you for any help.

Hi Ters.
From my papers.
subtransient reactance ( saturated) 12-30% 20-40%
transient reactance ( saturated) 20-45% 20-40%
synch reactance ( unsaturated) 80-180% 80-180%
saturated value are lower 5-10%
NS reactance X2 10-25% 30-50%
take in accounr X2=0.5(X"d+X"q), also for transient.
X0 5-20% 5-25%

This table actually for silent pole generators.
first column for the GEN with damper winding, second w/o.
Regards.
