Hello everyone. I'm having some issues on a simple task. I did some stability simulations. trip lines, gens... Everything OK. But when I tried to plt freq, my out file has feq deviations instead of absolute values.... I mean I would like to see if my machine rises from 50 to 51HZ when I trippped a load....

I tried chapter 22 of help guide, but no light yet...

any help... I'm sure its simple, but I can't find it.

Thanks in advance. Odin

In PSSPLT, use FUNC to apply an scaling function to the raw frequency signal before plotting [example for 60 Hz]:

FUNC
2
60*(1+A)
SLCT
8
59.5 60.5

In the GUI, the direct plotting implementation has a FUNC feature under Edit\Plot Attibutes but I have not used it. Outside the GUI and PSSPLT, you can export the f-channels to excel, execute a similar scaling function and then plot.
