Abstract

This paper presents the effect of magnetizing inductance on self-excitation. It also describes the loading analysis of an isolated induction generator, and how the operating frequency and generated voltage are affected by the change in operating slip value for regulated and unregulated rotor speed. Wind-powered self-excited induction generators have an input wind which is not controllable, but they can be set to operate within a given variation of speed. The experimental and simulated results for a dynamic generated voltage, frequency, and power are presented. The dynamic electromagnetic torque produced by the induction generator is also given. A dSPACE DS1102 digital signal processor card is used for data acquisition and for control of the driven speed.
