Hello, i added a wind turbine generator,following a post here in a modified IEEE14 bus system. When i run a dynamic simulation with an unbalnced fault (X=0 pu and R=0 pu) at a bus and see the relative angle plot, the wind turbine angle in relation to the swing bus steadily decreases. I started the fault duration at 0.01 sec and it still happens the same. Why is that happening?

I have also tried replacing a generator with a wtg and still the same happens.

Here i present you the files. ://drive.google.com/file/d/1b8lOAtrokc1M0vFqFbJHr-1cdIhjdH/view?usp=sharing (couldnt't post it so add https)

Thank you
