摘要:
?针对双馈风力发电机无速度传感器模型参考自适应算法中纯积分环节造成的直流偏置和定子磁链振荡问题,提出磁链振荡改进控制策略。以分析双馈电机定子磁链振荡产生的因素为基础,建立定子磁链振荡模型,并通过对双馈电机定子磁链定向矢量控制原理的分析,提出将模型参考自适应算法中的定子磁链观测与双馈电机矢量控制结合起来考虑,利用定子磁链微分反馈和有功电流共同作用来抑制观测定子磁链振荡的控制策略。实验分析表明,该方法能有效抑制定子磁链的振荡和过冲,准确观测双馈电机转速,在亚同步速、同步速、超同步速 3 种状态下具有良好的动静态性能。
Abstract:
?To solve the DC drift and stator flux oscillation problem caused by pure integral link of model reference adaptive algorithm in doubly-fed induction generator (DFIG) speed sensorless control,an improved control strategy of stator flux oscillation was proposed. The model of stator flux oscillation was constructed by analyzing the factors of stator flux oscillation,and the modified control scheme was proposed by analyzing DFIG stator flux oriented vector control principle. The proposed control strategy considered the control of DFIG vector control and stator flux observation in model reference adaptive algorithm synthetically,and therefore the stator flux oscillation was restrained by controlling the stator flux differential feedback and active current. Experimental results show that the proposed method can effectively suppress the oscillation and overshoot of the stator flux,and observe the speed of DFIG accurately,and has good dynamic and static performance in the subsynchronous speed,synchronous speed and supersynchronous speed
