Hello, I am studying power system stability. I want to get some information of psspy. Plz, help me.

I want to know the parameters which decide ramp rate of generators in the wsieg1 and GGOV1 models of PSSE. I mean, which parameters are they decided ramp up/down rate of generators in the model, WSIEG1 and GGOV1 ?
I want to simulate for GGOV1 as secondary control during dynamic simulation. I found this website, if I want to simulate it, Pmws should be changed during dynamic simulation. In this point, I wonder about Kimw (power controller gain). If I entered the value as 0.01, they just follow supervisory load controller sepoint. Why didn't they respond to governor response?

The maximum ramp rate is set by parameter Uo (open) and Uc (close) in model WSIEG1.

In model GGOV1 the maximum ramp rate is set by parameter Ropen and Rclose.

I don't understand the second question. The secondary control with gain Kimw will override the droop contol and bring the generator electric power back to Pmwset in steady state. That is the meaning of secondary control.
