A sensorless flux oriented control scheme for a DFIG connected to a DC link
In this paper, a novel sensorless flux-oriented control scheme is presented to connect a DFIG to a dc link with arbitrary stator frequency. The rotor side of the DFIG is connected to the dc link through a converter while the stator is connecting to a three phase diode bridge with the dc side connected to a dc link. The control method used in this paper is regulating the stator frequency and the d-q axis voltage of the diode bridge to operate the DFIG at a desired stator frequency and generate the required power. The low-order harmonics in the stator current of DFIG are detected and regulated through control of the rotor currents based on multiple reference frame theory. Matlab/Simulink is employed to investigate the performance of proposed methods.
