Abstract: Double-vector model predictive current control of a DFIG improves the problems of fixed voltage vector direction amplitude, low current waveform quality and large torque ripples in traditional single-vector model predictive current control. However, there are still some current ripples and torque ripples only when q-axis current is deadbeat controlled. In this regard, the number of vectors is increased on the basis of double vectors, and a three-vector model predictive current control strategy is proposed. The desired voltage vector in this strategy is composed of two adjacent effective voltage vectors and a zero vector, and its range can cover any direction and any amplitude. The current of d axis and q axis of the side of the doubly-fed wind turbine is also deadbeat controlled, so the current pulsation of d axis and q axis reduces effectively. The simulation and experimental results show that, compared with single and double vector model predictive current control strategies, the current ripples and torque ripples under the current control of the three-vector model prediction reduce significantly, showing a better dynamic and steady-state performance.
