A General Model for Describing the Performance of Brushless Doubly-Fed Induction Machines = نموذج عام لوصف أداء الآلة التأثيرية اللافرشاتية مزدوجة التغذية

Allam, Said M.

This paper presents a generalized model, by which the dynamic and steady-state behaviour of the Brushless Doubly-Fed Induction Machine (BDFIM) can be precisely predicted. The investigated doubly-fed machine has two sets of three-phase stator windings with different pole numbers. The rotor is a squirrel-cage type with a simple modification in order to support the two air-gap rotating fields that are produced by the stator windings and have different pole numbers. The machine model is derived in the qdo-axis variables. The qdoaxes are attached to rotor and hence, it rotates at the rotor speed (Zm). The electromagnetic torque expression is also obtained based on the presented model. The winding function method is applied as a convenient approach that can be used for machine-winding inductances calculations. Sample case studies are introduced to examine the performance of the proposed model in both steady-state and dynamic conditions.
