Modeling of an isolated induction generator considering saturation effect
Résumé
This paper proposes a self-excited induction generator model with saturation
effect for power generating mode in a remote site. The model is led through the space
vector mathematical formalism and allows one to analyze the steady and dynamic states. It
is developed for a squirrel cage induction machine. This model provides magnetizing inductance variation able to influence the build-up and the stabilization of voltage generation
when the load changes. The final result is a realistic approach model which takes into consideration the dependency of the magnetizing inductance versus magnetizing current. This
novel model is validated through experimental measurements to demonstrate its validity
and practicability.
