hello everyone
I'm still have some mistake in dynamic simulation for IEEE-39bus after any disturbance (ex. loss of Generator or trip line..)
More clearly it's shown in the output results : frequency and voltage "NAN" I do not know what's the wrong
I selected channel setup wizard categories to output : Bus
please I need help and
thank you all
Hi Yasmine,
Normally the NaN value occurs when the simulation doesn't converge correctly. In my experience I've gotten NaN values when the channel values blow up. The first thing to check is that the initial solution is flat start before any contingencies occur. There is a possibility that the particular contingency you create is causing the solution to blow up as your case cannot handle it, or it can have something to do with the actual dynamics of the generators you specified in your .dyr file.
