Керування машиною подвійного живлення з матричним перетворювачем в колі ротора при несиметрії напруг мережі живлення

Abstract

Control algorithms of doubly-fed induction generator with matrix converter under unbalanced grid voltages have been considered. Comparison of the strategies to improve the performance of DFIGs under unbalanced network conditions suggests that some control strategies achieves selective control targets, namely: symmetric and sinusoidal stator currents, removing stator reactive power ripples; cancelation of stator active power ripples, torque ripples minimization. Control strategies of matrix converter as part of DFIG under unbalanced grid voltage conditions have been considered.
