Design and analysis of brushless doubly fed reluctance machine suitable for wind generation applications

One of the more promising generator options for renewable energy sources such as wind energy is the brushless doubly fed reluctance generator. Various benefits include partial rating converter, absence of rotor winding and brushless operation, which makes it very interesting for investigation in detail for commercialization. This paper highlights certain design aspects and critical areas in design of such machine. A laboratory prototype of three phase brushless doubly fed reluctance generator is designed and fabricated to examine various aspects. The analysis of this machine is carried out by using finite element method along with simulation studies at steady state level. The results obtained are presented and inferences are drawn.
