Abstract

Understanding the significance and prospects of self-excited induction generators (SEIGs) in wind energy application, this paper elucidates the significance of incorporating the proximity effect in the conventional model of SEIG. An analytical model to incorporate the proximity effect in the rectangular rotor bars of the SEIG is developed and built into a computer program to elicit the accuracy of the developed SEIG model. The calculated results are experimentally verified in the case of two 7.5 hp aluminum- and copper-rotor SEIGs under static loading conditions, through an exclusive qualitative analysis of real and reactive power profiles and rotor copper losses, as a function of the proximity effect.
