Wind Turbines Equipped with Self-Excited Induction Machine in Autonomous Mode: Analytical and Numerical Starting Studies

This paper deals with the definition of a new proceduredevoted to the analysis of an autonomous self-excitedinduction generator (IG) comportment. First, for thesteady state, a new single phase equivalent scheme isproposed. Then, this scheme is used to analyze the self-excited starting. Numerical study based on spacephasor theory, as well as experiments, allow to validatethe theorical approaches.
