How to model over frequency relay tripping
I am trying to model relay trip action to trip loads/feeders for over-frequency conditions in PSSE dynamic simulations. However, I can't seem to find any suitable model. Most relays are based on underfrequency
LDSHBL, LDSHOW, LDSHZN, LDSHAR, LDSHAL
The only over-frequency relay I found are the:
FRQDCAT, and FRQTPAT,
However, they only disconnect generators, or the whole bus. Is their any over-frequency relay that would trip a load or a percentage of a load?
