摘要：

A H-DPC(Hybrid Direct Power Control) strategy of doubly-fed induction generator under unba-lanced voltage conditions is proposed. Firstly, the modulated voltages of stator active power and reactive power are constructed in the stationary reference frame, which can realize the power no-difference tracking control without phase locked loop. Then, the extended active power and reactive power are introduced into the control system, and combined with the conventional active power and reactive power, the hybrid power feedback is constructed to realize the operation control objectives of constant active power, constant reactive power and three-phase balanced stator current under unbalanced voltage conditions. This method does not need phase separation and extraction of voltage and current, which simplifies the implementation of the control system. Finally, the results of hardware-in-the-loop experiment verify the effectiveness of the proposed H-DPC strategy. © 2022, Electric Power Automation Equipment Press. All right reserved.
