Abstract:
This paper presents an improved steady-state model and performance study of a brush less doubly fed twin
stator induction generator (BDFTSIG). The proposed steady-state model is modified to take into account
magnetic saturation and stator and rotor core loses. These modifications are essential for realistic results in
the BDFTSIG applications as the control stator machine works at variable flux levels and can easily come
into magnetic saturation while the rotor frequency is normally much higher than that in standard induction
machines so that rotor core losses cannot be neglected. The model is verified by experiments and the
performance analysis indicates the feasibility of the BDFTSIG for variable speed generator applications.
