.dyr file?

edit

This is a description for creating a dynamics file (.dyr) from the PSS/E 33 interface.

After first opening the case file (.sav or .raw) you will be working with, you can go into the Dynamics Tree View, either by clicking on the Dynamics Tree View tab or by selecting Dynamics Tree View in the View menu.

The elements in your case file for which you can add dynamics can be found by looking through the tree. Double clicking one of these elements will bring up the Dynamics data spreadsheet where you can add dynamic models.

For example, a generator might have None written beside it if it has no model to describe its dynamics. By right clicking this box a model from the set of standard models can be chosen, and parameters can be specified. Parameters highlighted in red are not permitted.

Once all of the models you require are specified, you can save the resulting file as a .dyr file. With the Dynamics data spreadsheet open, the Save dialog box gives the option of saving the Dynamics Model Data as a Data file (.dyr).

Here's a quick turn around I have practiced with great effectiveness not using PSS/E but PowerWorld.

1. Download PowerWorld academic version.
2. Open any case in PowerWorld, choose largest case that can be loaded.
3. Go to the stability add-on.
4. 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.
5. Save the case. Run the case in PowerWorld stability and even allow PowerWorld to check and correct the dynamic data.
6. Save the dynamic data in dyr format. - PowerWorld has a feature on this.
7. Open the dyr file in a text editor. Edit as possible (bus numbers, bus names to match your case.)
8. Read dyr file in PSS/E. And you are all set!

You also can write .dyr file by notepad or any other compile program. In this file, you write model of dynamic elements and their data. you can find the syntax in POMV2.pdf( Psse 30) or PSSEdocumentation.pdf (PSSe33). Here is an example:
