Hello,

I have the understanding that under a dynamic simulation PSSE calculates the positive sequence matrix and performs and the generator is also represented in the positive sequence. This situation works great with balanced faults.

However, with unbalanced faults under a dynamic simulation PSSE does not permit to read the negative sequence voltage at the generator terminals until PSSe 34.7. Is this correctly understood?

Unfortunately, I am not able to find evidence in the manual of confirmation or denying of my question in the manual.

Thus, I would also to like to ask if anyone knows where this information is written in the manual? Thank you.
