Here's a quick turn around I have practiced with great effectiveness not using PSS/E but PowerWorld.
- Download PowerWorld academic version.
- Open any case in PowerWorld, choose largest case that can be loaded.
- Go to the stability add-on.
- Put dynamic models in each component (gens, exciters, governors, PSS, HVDC, SVC, wind turbines, etc). - PowerWorld has default dynamic data for each but you have to edit out some parameters like MVA base, etc.
- Save the case. Run the case in PowerWorld stability and even allow PowerWorld to check and correct the dynamic data.
- Save the dynamic data in dyr format. - PowerWorld has a feature on this.
- Open the dyr file in a text editor. Edit as possible (bus numbers, bus names to match your case.)
- Read dyr file in PSS/E. And you are all set!
