摘　　要：双馈风力发电机采用双矢量模型预测电流控制策略时,相较于单矢量模型预测电流控制扩展了备选电压矢量范围,但将滚动优化次数增大两倍,导致计算量增大从而影响其实用性。针对此问题,在双矢量模型预测电流控制策略的基础上提出一种基于双矢量的快速预测电流控制算法。首先利用有效电压矢量以及合成电压矢量的运动轨迹将电压平面划分为6个扇区,各扇区又细分6个子扇区;其次通过判断参考电压矢量所在扇区,选择下一时刻最优的第1矢量和第2矢量;最后,合成新的电压矢量,实现对系统的运行控制。并通过仿真与实验验证,结果表明所提方法在显著降低算法复杂度的同时保留了双矢量模型预测的良好控制性能。While the adoption of two-vector model predictive current control(MPCC)by the doubly-fed induction generator(DFIG)extends the range of alternative voltage vectors compared with that of a single vector MPCC,the number of rolling optimization times is doubled,resulting in an increase in computational complexity and thus affecting its practicability.To address this problem,a two-vector based fast predictive current control(FPCC)is proposed on the basis of the two-vector MPCC strategy.Firstly,the voltage plane is divided into six sectors by the active voltage vector and the synthesized voltage vector trajectory,while each sector is further divided into six sub-regions;Secondly,by judging the sector where the reference voltage vector is located,the first and second optimal voltage vectors for the next step are selected;Finally,the new voltage vector is synthesized to realize the operation control of the system.Simulation and experimental results show that the proposed method maintains the effectiveness of two-vector MPCC while significantly reducing the control complexity.
