DSP-based doubly fed induction generator test bench using a back-to-back PWM converter

Present paper describes the design of a doubly fed induction generator (DFIG) test bench with active crowbar, using PWM voltage-fed inverters connected between the grid and the rotor. A vector-control scheme is proposed in order to control the power-side and the rotor-side of the converter. A control board, based on a digital signal processor (DSP) and a FPGA, has been developed to manage the overall equipment. Real-time system supervision is implemented by a monitor program.
