A Study on the Maximum Power Control Method of Switched Reluctance Generator for Wind Turbine

This paper deals with modeling and power control methods of a switched reluctance generator (SRG) driven from the wind power generation system. To consider electromagnetic nonlinear characteristics of SRG, the flux linkage and torque of the designed generator computed by a finite element method (FEM) are applied to the SRG model. And the SRG model is controlled with a required output curve depending on the speed of the generator using optimized switching angle which has been analyzed in advance to maximize its efficiency. The power control algorithm is applied to a manufactured 3 kW prototype SRG. The simulation results are compared with the experimental ones for validation.
