ship/shore power supply, "cold ironing"

[aleksandrsLV]

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.

Not sure what would be different on a marine-specific machine, but Cat's SR4B alternator data is linked below. It seems to contain the majority of the data you are looking for. The rest is probably on the website somewhere.
