New wind turbine emulator based on DC machine: hardware implementation using FPGA board for an open-loop operation

摘要

This work deals with the development of an open-loop wind turbine emulator to verify the system operation with respect to the wind profile. The emulator consists essentially of a 300 W DC motor powered by DC/DC buck converter which controlled through field-programmable gate array (FPGA) and pulse-width modulation strategy. The motor rotational speed allows to imitate proportionally different wind velocity. A hardware test bench based on the fast prototyping method using MATLAB/Xilinx System Generation (XSG) environment and FPGA board of wind turbine simulator is built to validate the simulation results. Simulation and experimental results confirm the efficiency of the implemented method to make the proposed emulator able to react as a real wind in laboratory.
