Hello
Could somebody tell me how can I modelised a VFD in SKM?
Thank you

Yes, I have a DC module in SKM.
Thanks
RE: SKM modelisation
If it has a bypass contactor, I'd just ignore the VFD for fault calculations. If there is no means of bypassing the VFD and the VFD can not feed back into the line, I'd just ignore the motor for fault calculations. With a four quadrant drive you might get some fault current back out but not as much as the motor itself would produce. I don't really know what a four quadrant drive does during faults, you might well not get any fault contribution.
So, with bypass contactor ignore the VFD for fault calculations and without bypass contactor ignore the motor for fault calculations. For load flow you need to account for the VFD losses as well as the motor loads. Beyond that it really depends on what you are trying to get out of your model.
RE: SKM modelisation
I will try to modelise all posibility and I will analyse the results.
