Abstract

Abstract: This paper proposes a Fuzzy Logic Controller for improvement of the steady-state response of a Doubly Fed Induction Generator used in a wind energy system, and governed by means of a Deadbeat Power Controller. The generator mathematical model is consistent with the Stator Flux oriented strategy in the synchronous reference frame. Different simulation scenarios were developed in Matlab/Simulink to evaluate the dynamic and the steady-state responses. In order to obtain experimental results, the simulated scenarios were repeated by means of a test bench and a Digital Signal Processor board. These results demonstrate that the response still follows the power references imposed, despite the fact that the generator parameters ( R r, L s and L m ) were varied in a 30%. A lower steady-state error is also achieved when compared with a Deadbeat and a classical PI controller. All the aforementioned evidence the proper application of this Fuzzy Controller in a wind power system based on a Doubly Fed Induction Generator. Highlights: A novel Deadbeat Fuzzy Controller developed for a Wind Power System DFIG based with simulated and experimental results during normal operating conditions. The application of the deadbeat fuzzy controller is a valid alternative to the DFIG Stator Power Control. Experimental test bench using a 3 kW DFIG and a DSP TMS320F28335 card.
