Dear forum users,

I have a very simple circuit shown as attached (google drive). Power flow study runs fine. But I got issues with the dynamic simulation. Here is what I did for the dyna simulation, after the initialization, I let the circuit run for 1sec. then I created a three-phase fault on bus 1100, then clear the fault after .1 sec. then run the circuit to 2sec. I found after the dynamic simulation, the generator and transformer on bus 1111 are all not in service anymore.

Can anyone suggest what went wrong? Thank you!
