What is a positive sequence model of an induction machine?

I'm trying to understand a 3 phase induction machine model used as a generator in a Doubly Fed Induction Generator (DFIG) arrangement in Simulink.

In this model for the induction generator component, they have stated that the model is a "Positive sequence model" of the induction generator.

Whats the reasoning behind modelling it in this way for this application?
What are the implications and limitations of this?
What about the negative and zero sequences, arnt they worth considering?

Sorry for the number of questions, I wanted to explain my lack of understanding as comprehensively as possible:smile:

Zero and negative sequence models are useful only when the three phases are unbalanced.
