Description

The current description is: Governor Speed Changer Droop. This is the change in generator power output divided by the change in frequency normalized by the nominal power of the generator and the nominal frequency and expressed in percent and negated. A positive value of speed change droop provides additional generator output upon a drop in frequency.

We use the term “Governor Speed Changer Droop” One could read this as the droop if the speed changer of the governor. Is this what we want? Could we just say “Governor speed droop”

Then the rest defines “the change in generator power output divided by the change in frequency” which is deltaP/delta_f. I guess this maybe also works, but I see it mostly defined change of frequency divided by change of change of P.
Then we have – normalized, percent, negated,… Maybe we can just write as equation.

The description becomes cumbersome to describe the behavior, could be improved by incorporating an equation.
