Abstract :
A research platform for wind energy system is developed in this paper. An inverter fed induction motor drive the wind generator replacing a real wind turbine. The power-speed characteristics of a wind turbine are physically implemented by an induction motor drive. For a given wind turbine characteristics, the shaft torque of induction motor is calculated by the given wind speed and measured generator speed. With the rotor flux oriented transformation, the q-axis current of induction motor can be used to control the motor torque, and the d-axis current is used to regulate the rotor flux. Using the space vector PWM algorithm, the 1 GBT inverter drives the induction motor to output the required torque as a real wind turbine. The experimental results show that this scheme is viable and accurate.
