To run a transient stability study (in PSSe v.33), you need:

• a dynamic dataset that has a well behave base case and reasonable tuned dynamic data.
• an accurate representation of the fault, with clearing times. Hopefully, no other event occurred that would impact the simulation results, else, include them.
• Add channels (variables like generator angle, power output, bus voltage) to monitor during the simulation and to plot later.
• Run a transient simulation for 5 to 10 sec, with fault applied at 1 sec. When plotting, the period 0-1 sec should be a flat line for all variables monitored, confirming your dynamic dataset is acceptable.
• Check the manuals (API, application guide,..) for information on how to execute a dynamic run. Perform a test run on the savnw case (all data provided in the "example" folder of PSSe folder structure). Check the post "The tutorial steps for PSSE and Python for starters" and the net for other PSSe tutorials.
• Cross your fingers.
