Control of a Grid Connected DFIG Based Wind Turbine Emulator

Abstract

This work presents the implementation of a wind energy conversion system based on a Double Fed Induction Generator (DFIG), driven by a DC Motor (DCM), which emulates the transient and steady state characteristics of a wind turbine. The experiments present the transient of the transfer of active and reactive power between the power grid and the DFIG during hypo and hyper synchronous modes. The control algorithms are implanted in C, using dSPACE DS1104 control board to drive both machines. The experimental results confirm the advantages of using this structure for wind energy conversion system and the effectiveness of the control algorithms.
