摘要

针对永磁同步风力发电机驱动系统中定子电流谐波的问题,提出一种基于准降阶广义积分器（QROGI）的电流谐波抑制方法。将QROGI控制器引入电机控制电流环,利用QROGI控制器在设定交流频率处的高增益以抑制谐波电流;针对旋转坐标系下谐波电流分量在交直轴上表征为交流量,通过在电流内环叠加QROGI控制器实现对谐波电流的控制;对叠加QROGI的电流环控制器进行详细理论分析,对电流环控制器参数进行设计,给出详细的分析过程及控制器参数定量计算方法。最后通过搭建半实物实验平台验证了所提方法能够对永磁同步风力发电机定子谐波电流进行有效抑制。

Abstract

To reduce low order harmonic components of stator current in a permanent magnet synchronous wind generator driving system, a suppression method for current harmonics is proposed in this paper on the basis of quasi reduced order generalized integrator （QROGI）. The QROGI controller is introduced to the current loop of motor control system to suppress harmonic current using its high gain at certain AC frequency. In the rotating coordinate system, a harmonic current component is represented as an AC quantity on the direct axis and quadrature axis respectively, which is controlled by the superposition of QROGI controller in the current inner loop. This superimposed current loop controller is theoretically analyzed in detail and its each parameter is designed as well, where the design process and quantitative calculation method are offered step by step. The hardware-in-the-loop experimental platform is set up respectively and the corresponding results show that the stator harmonic current can be suppressed effectively by the proposed method.
