What is the relationship between GREF and PMECH

asked 2024-11-19 11:39:58 -0500

Based on this PPSPY post "What is the base value for the generator GREF? " the GREF is represented as

 GREF = DROOP*PMECH

However, I sometimes encounter cases where this equation is not giving the expected answer compared to PSSE simulations. Is this GREF equation a general equation for all governor models? or is the equation different for different models?

The equation is for TGOV1 governors only!

Thanks perolofl. Is there a source or guide on how to approach other governors? I found some other PSSE governor models where the equation still holds, and some where it holds in GSTR simulation, but not in grid-connected. While other times, it does not apply at all
