ship/shore power supply, "cold ironing"

(OP)
Hello!

I'm now looking into the problem of so called "cold ironing" - ship in port supply with shore power, and would like to simulate the transients of the matter. So I'm in need of synchronous generator precise model, which I can use for my research. I would be grateful to recieve parameters of typical marine synchronous generator (with rated apparent power ~900kVA, rms voltage ~400V, frequency 50 or 60Hz, salient pole etc) as indicated below:
(index d stands for direct axis, index q - for quadrature axis)
Fn    [Hz]    Rated frequency
rs    [p.u]    Stator winding resistance
xss    [p.u]    Leakage reactance of stator winding
xc    [p.u]    Characteristic reactance (see remark below)
xd    [p.u]    Main reactance
xd’    [p.u]    Transient reactance
Td’    [sec]    Transient time constant
xd’’    [p.u]    Sub-transient reactance
Td’’    [sec]    Sub-transient time constant
xd’’’    [p.u]    Sub-sub-transient reactance
Td’’’    [sec]    Sub-sub-transient time constant
xq    [p.u]    Main reactance
xq’    [p.u]    Transient reactance
Tq’    [sec]    Transient time constant
xq’’    [p.u]    Sub-transient reactance
Tq’’    [sec]    Sub-transient time constant
xq’’’    [p.u]    Sub-sub-transient reactance
Tq’’’    [sec]    Sub-sub-transient time constant
Sn    [VA]    Rated apparent power
Un    [V]    Rated Rms value of the phase - to - phase voltage
Fn    [Hz]    Rated frequency
Pp    [1]    Number of pairs of poles
Ifd0    [A]    Excitation current corresponding to the no - load rated voltage on the air - gap line (no saturation)
Connect    [-]    Connection of the three - phase stator windings
Power Factor
solid iron rotor/laminated rotor

And also any other values/parameters You find important.
