Control of Switched Reluctance Generator for Wind Energy Applications

This paper discusses how the switched reluctance generator (SRG) converts mechanical energy from wind via turbine into electrical energy as directed by an electronic controller. Starting with a review of the electromechanical energy conversion principles, the paper examines the implications of the energy conversion process on how the SRG is controlled. The structure of the SRG controller for speed-control and power-control applications is discussed. The methods for commutation of the SRG are discussed. Concepts are illustrated with a 5-kW SRG designed for wind energy applications where low speed high torque is required.
