Winding function approach based design of novel five-phase brushless doubly fed induction generator

The paper presents the concept of the new design of the five-phase brushless doubly fed induction generator. The generator is dedicated to the modern wind turbine. The innovative design approach uses a five-phase power supply from the stator control winding side of the generator with a stator three-phase classic power winding. The research results presented indicate that the electromagnetic coupling between the control and power windings of a brushless, doubly fed induction generator can be avoided. The five phase control winding allows for more flexible machine control and also opens new possible configurations in terms of winding distribution and core designs for the brushless doubly fed generators.
