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. (C) 2018 ISA. Published by Elsevier Ltd.
