Hello all ,

After simulating the transient stability in ETAP in which a fault occurs in a network and it is cleared after 0.2 seconds , the relative angle and power of generators fall to zero after being a certain value before the fault. I also did exciter and PSS for the generator and it is connected to the same busbar as another turbine of same rating . What is the reason and how to fix it ?

It is a big network , the libyan national grid where i'm performing a study on the transient stability on the network on certain regions, are there any details in particular that would help?

Ok, so can you share screenshots from ETAP: active power, reactive power, current and voltage of your studied generators.
