Analysis of self-excited induction generator by spiral vector theory

Self-excited induction generator (SEIG) is widely used for power generation in remote location. This paper attempts to unify the steady-state and transient analysis of SEIG using spiral vector theory. Normally phasor notations are used for steady state analysis; instantaneous phase variables, two axes or space vector approaches are used for transient analysis of AC circuits or machines. This paper presents the spiral vector method of analysis of SEIG. Spiral vector theory can be used for unified analysis of steady state and transient state in self-excited induction generator.
