I have a few steps you might want to follows:
- Looking for dynamic models. Each controls has one or more than one dynamic models, for example gorvernor,turbine and exciter for a generator. You can see the block diagram, syntax and typical parameters of built in models in MODELS documents of PSSE. Or you can search in the internet for some available benmark dyr files.
- Paste those parameters to a txt file and save as a .dyr file.
