摘要

为了提高有源电力滤波器的可靠性，针对负载电流波动和负载突停等工况时导致直流侧电压波动过大而无法正常补偿谐波等问题，研究了一种基于多同步坐标旋转的直接谐波提取方法，并将d-q谐波提取方法和直接谐波提取方法对直流侧电压控制的影响进行了分析和对比。提出了把直接谐波提取方法和复合重复控制相结合的指定次补偿控制策略，该策略不仅由于采用直接谐波提取保证了系统的可靠性，与复合重复控制结合也保证了系统的动态性能和稳态精度，而且可以指定次谐波补偿，补偿灵活。仿真和实验结果证明了研究内容的有效性。

Abstract

To improve the reliability of the active power filter (APF) in face of the DC voltage fluctuation too large to properly compensate for harmonics during load current fluctuation and load sudden stop

a selective harmonic direct detection method based on multiple synchronous rotating coordinates is proposed. And the DC-side voltage control effects are analyzed and compared for d-q harmonic currents detection method or the direct detection method used. A control strategy combining the direct detection method with composite repetitive control is proposed. This strategy not only has direct harmonic detection to ensure system reliability

but also combines the composite repetitive control to ensure dynamic performance and steady-state precision of the system

plus its ability to complete selective harmonic compensation that is flexible. Both simulation and experimental results verify the effectiveness of the research contents.
