Design, control and 2D-FEM validation for an Double Stator Winding Induction Generator

This paper will present the key design equations and control design model of the Double Stator Winding Induction Generator (DSWIG) to achieve wide-speed-range operation with reduced capacity of the static power controller for low power wind or hydro applications. The proposed induction generator consists of a standard squirrel-cage rotor and a stator with two separate windings wound for a similar number of poles. Moreover, the system control strategy using the stator flux orientation is consequently proposed. A 2D finite-element analysis with specialized software is given to prove the effectiveness of the design equations and find the main characteristics of the machine.
