Why does the rotor angle become such a large value like -1000 degrees in dynamic simulations after load change

I changed the load in dynamic simulation recently. But I found that the rotor angle changed from 1.3 degrees to -1000 degrees. How can I transform these values into per-unit values? Please help me with that problem!

Thank you very much!
