Doubly fed induction wind generators model and field orientation vector control design and implementation on FPGA

Abstract

Dynamic systems emulators are very efficient techniques to design a system that mimics a precise behaviour of real systems. Moreover, they are designed to reduce costs as well as to give more flexibility concerning experimental purpose. The objective of this work is to develop an FPGA-based system, that emulates the overall doubly fed induction generator (DFIG) and active and reactive power vector control scheme for wind generators applications. The advantage of such an approach is to design a system which is more open to structural changes, has the possibility to be changed and could be adapted to several operating scenarios at lower costs. The DFIG with vector control scheme have been modelled using Xilinx System Generator and implemented in FPGA. The efficiency of this approach is assessed, yet, proofed considering reference tracking attitude of the controlled machine comparing to software simulation technique.
