Design of self-excited induction generators for wind applications

Wind energy schemes have the potential to substantially reduce the consumption of fossil fuels used in the production of electric energy. The self-excited induction generator has found renewed interest as a low maintenance wind generator for standalone and grid integrated applications. This paper will present a full analytical model of the dynamic response and steady state operation of the induction generator. Design equations describing self-excitation, loss of excitation and voltage regulation are presented. These closed form analytical solutions can be part of an integrated design process and intelligent control design for a self-excited induction generator allowing maximum wind energy capture.
