GENTRA not converging
Hello guys,
I wrote a transient stability code in Python for my thesis, and now I'm asked to validate some of my results using PSSE. I already read some guides in about dynamic simulations in PSSE and did a test with the classic model. For some reason my simulations fails to converge (i.e. goes nan) with the GENTRA model. I really need to use this model, as it is the one I programmed in my stability code.
After doing some testing I realized that if I change my ZSOURCE to be different than X'd, it will converge but to won't give a good result. When I place ZSOURCE to be the same value as X'd, I will get the same initial conditions but it won't converge, even in steady state (no fault).
Here are my files: http://www.mediafire.com/file/zdigka4bc3xqdf0/PSSE.rar/file (www.mediafire.com/file/zdigka4bc3xqdf...), the .sav is has already the generators and load converted.
I'm pretty lost right now, so I would really appreciate some help, Thanks in advance, Martín
