Optimized Wind Turbine Emulator based on an AC to DC Motor Generator Set

Abstract

This study presents an Optimized Wind Turbine Emulator (OWTE) based on a DC generator driven by a three-phase Induction Motor (IM). The IM speed is varied using an AC drive that converts fixed RMS voltage and frequency to variable ones due to v/f control. The frequency reference of the control was calculated through optimized equations of a wind turbine model for maximum power and torque. The overall system was simulated on Matlab/Simulink using a wind speed profile scenario. An experimental test bench controlled by a TMS320F28379D card was set up in the laboratory to confirm the effectiveness of the obtained simulation results.
