Abstract

The paper presents a generalized unified electromechanical current and flux models of self-excited induction generators. A k-factor saturation method is used to account for magnetic saturation in previous models. The neutral connection of the machine is also included. Numerical modeling of self-excited induction generator unbalanced transients according to machine grounding systems is proposed. To illustrate an application, balanced and unbalanced short-circuit tests occurring on a wye-connected double squirrel cage self-excited induction generator are simulated and discussed
