Abstract

Self-excited induction generators (SEIG) are used in small scale generation systems such as small wind turbines and micro-hydro schemes where a grid connection is not available. In such applications, there is a strong need to model the generator as accurately as possible in order to obtain a realistic estimation of the machine behaviour and dynamics. In this paper, a generalized dynamic model of a three-phase self-excited induction generator (SEIG) in the natural abc reference frame is presented. The developed model accounts for the significant effects of magnetic saturation by expressing the magnetizing inductance as an exponential function of the magnetizing current considering both the value of the inductance and its rate of change with the magnetizing current (dL_m/dim). The model is used to investigate the SEIG steady-state and transient behaviours at balanced, unbalanced and fault conditions.
