Abstract :
A novel wind turbine emulator (WTE) based on a torque controlled Brushless DC (BLDC) motor is presented, which can emulate the steady-state and dynamic characteristics of an actual wind turbine. Variable wind speeds, turbine inertia and torque oscillation caused by tower shadow and wind shear are all considered in the construction of the actual wind turbine model and the torque controlled BLDC model . A PI regulator is employed to make sure that the output torque of BLDC tracks the reference torque. The simulation results based on RT-LAB real-time simulation platform verify the validity of the proposed WTE.
