I am looking to determine if there are any potential problems with operating two Zn Earthing transformers in Parallel ?
They are connected to an 11kV system that is energised from 3 ungrounded 11kV generators. The earthing transformers are to the same design, but have slightly different zero...
Apologies for posting this on this site rather than the EEUG forum, but there seems to be more activity here !
Has anyone tried in ATPdraw to use the loadflow (FIX SOURCE) feature while at the same time using the Caged rotor induction machine (UM3) auto inititialize feature ?
I'm seeking to...
Can anyone point me in the direction of a good resource on gas turbine modelling. I need to model a 30MW gas turbine in ATP for load shedding studies and am looking for block diagrams (and any TACS examples if I'm lucky !!!!)
Thanks

I am modelling a 250 kVA diesel generator to estimate the voltage and frequency excursions that occur due to step changes in load. I have a good transfer function (G(s)) for the alternator, avr, exciter and will hopefully be obtaining one for the governor/actuator system. I do not have...
Does anyone know what the typical inrush magnitude and time to decay is for a shunt connected air cored reactor ? I would imagine it can be a maximum of 2 x rating as there will be no remenant flux, and will be over with pretty quick due to no iron to be magnetized. I'm looking at a reactor...
