How to retrieve data from Dynamic studies?

edit

Hello everyone, I am trying to run a code where if the feeder has an MVA of a 2000, it will run a .idev file to trip lines in the system. The thing is I need to do this with Dynamic simulation, so when it is running the simulation, i want to code to see if the feeder goes to 2000 or higher, it will automatically trip those lines in dynamics? is there any way to do that?

like an if statement, but i don't know the data retrieval information for retrieving the MVA of a feeder on dynamics. so any help would be appreciated.
