摘要

通过对无刷双馈发电机的功率绕组电压定向的统一矢量模型进行研究,提出了一种不依赖电机参数的矢量控制策略。该控制方法通过控制控制绕组的d轴和q轴电压分量来分别控制无刷双馈发电机的有功功率和无功功率,同时针对两定子d轴和q轴变量之间的交叉耦合问题加入了补偿模块。相比其他补偿策略,该补偿模块更加容易计算和实现。该控制策略不需要使用电机参数,避免了电机运行过程中因参数变化带来的控制精度下降问题。为了验证所提出的控制策略的性能,搭建了变频调速试验平台。试验结果证明了该控制方法具有良好的控制性能和解耦性能。
        By researching the unified vector model of the power winding voltage orientation of the brushless doubly-fed generator( BDFG),a vector control strategy that does not rely on motor parameters is proposed. With this control method,the active power and reactive power of the BDFG can be respectively controlled by controlling the d-axis and q-axis voltage of the control windings; and for the cross coupling between d-axis and q-axis variables of the two stators,the compensation module is added.This compensation module is easier to calculate and implement than other compensation strategies. The control strategy does not require the use of motor parameters,which reduces the control accuracy caused by the parameter changes that occur during the operation of the motor. An experimental platform has been built to validate the performance of the proposed control strategy; the experimental results prove that the proposed control method offers both good control and decoupling performance.
