Thi s paper presents the development of Wind Turbine Emulator (WTE) for wind energy conversion systems (WECS), using a separately excited DC motor, controlled by a chopper and real-time interface card. The DC motor is controlled using PI regulator. The wind turbine emulator system inc\udes wind speed profiles, mathematical model of wind turbines, modeling of rotor blade characteristics and modeling of rotor inertia. Wind speed can be easily programmed. The proposed approach was implemented on DSl104 real-time interface card and Matlab/Simulink real-time control programming. The experimental results show the performance of proposed WTS.
