I don't have a deep level of experience with Dynamics, so I hope that someone can chime in and correct me if I'm wrong.

  • You cannot check the angles with Python while PSS/E is actually running the simulation. That means you'll need to stop simulating for a little bit and check the .out file for the monitored machine angles.

I propose something like this:

  1. Run for a short period of time after clearing fault (e.g. 1 second)
  2. Check the .out file using dyntools for the machine angle spread
  3. Either take action by tripping generators or continuing the study depending on the outcome of #2

Feel free to adjust the timing above, I've only used 1 second as a guide.
