I want to analyse the transient stability of a simple system over a long period of time. I do this because my ultimate goal is to run the simulation with real-time simulator for education purpose.

My model is really simple, one PV bus synchronous generator connected to a infinite swing bus via a bunch of inductance and resistance in serie and parallel. I simulate a fault at 0.5 sec and since i am simulating dampingless generator i expect my system to oscillate for the infinity

But.. When i run my model in phasor mode it run well and it do not diverge. But when i run it in discret mode with 20 us (as it will be on my real time simulator) the mecanical angle after the fault always increase until it reach instability.

btw i add up some extra load to help numerical stability as suggested in the help panel of the synchronous generator.I want to analyse the transient stability of a simple system over a long period of time.
