Hello.. I am using PSSE to perform dynamic simulation, the simulation was working perfectly for me, but I tried to delete some sub-systems from the network, and in parallel I have deleted from .dyr file the corresponding dynamic data. After doing so, I had issue while running the dynamic in PSSE, where when I try to initialize the dynamic case, the PSSE crashes. could you please help me or at least state the possible causes for this problem. Note: I have deleted only the busses from particular subsystem along with corresponding dynamic data. I did not make any other changes.

Have you solved the network after deleting the subsystem?

Does it crash if you don't delete the data from the dyre file?

There is no need to delete data from the dyre file. PSSE will just ignore dynamic models for objects (Machines etc) not present in the network.

- Yes I solved the power flow and it converges - yes still crashes even if I don’t delete dyre data
