Abstract
This paper presents mathematical models for
various generator-load configurations that accurately
determine the conditions for self-excitation and performance
characteristics of an isolated , three-phase, self-excited
induction generator operating under balanced or unbalanced
conditions .These models are derived using symmetrical
component theory along with the generator sequence
equivalent circuits. Using this technique a 4.5kW, 400/440V,
four poles, three-phase induction motor operated as a SEIG is
analysed under different balanced or unbalanced
configuration.
