Revision history [back]

Hi all,

I am trying to perform a simulation of a restoration process: Starting from a generator + load energize the whole system.

So when i connect a generator or a load, after the transitory period the frequency stabilizes in a level (under o over nominal) and I want that frequency to come back to normal. So the primary frequency control is working but not the secondary.

I've tried PLVFU1, using R=0 for the governor and the GGOV1 with control mode 0 (=isochronous) withiout success.

Any recommendation?

Thanks in advance
