Wind turbine emulator mimics the behaviour of wind turbine for hardware level simulations. This system has a DC motor coupled with the Induction generator, speed of which is controlled as per the speed reference calculated by solving the mathematical model of wind turbine. An induction generator is coupled to the DC motor and bidirectional inverter is connected to the terminals of the generator. Researcher can execute the mathematical models of their newly developed or modified wind turbine and can simulate the speed/power of profile of turbine on hardware environment directly for different wind speeds & pitch angle.
