How to ramp the value of exciter output voltage in dynamic simulation?

Hi, I'm new with PSSE. I am simulating the dynamic response of a synchronous machine (SMIB system) in PSSE.

I would like to know if it is possible to change the value of the exciter output voltage (Efd) according to a ramp with a defined slope (or alternatively with a defined duration) in a dynamic simulation? Sort of a "manual control" of the value of Efd.

Also, could you recommend a web page to start to learn to work with Python in PSSE. I am using the GUI to run the simulation.

PSSE does not have any facility to ramp EFD. However it can be done with some code in the CONEC file or with a user-written model.

thanks for the answer. How can I defined a user-written model for the exciter?
