摘要
有源电力滤波器(APF)可以有效地抑制谐波、改善电能质量。针对传统APF容量过大的问题,采用了一种新型APF拓扑结构,该拓扑由传统的APF和LC无源滤波器构成。通过对该拓扑电路性能的分析,建立了系统的数学模型,提出了一种电容电流反馈方法。采用多同步旋转坐标系的指定次谐波电流控制策略,提高系统的性能和稳定性。通过仿真和实验验证了所提理论分析和研究结果的有效性。
Active power filter(APF)can effectively suppress harmonics and improve power quality.Aiming at the problem of excessive capacity of traditional APF,a new type of APF topology is adopted.The topology consists of traditional APF and LC passive filters.A mathematical model of the system by analyzing the performance of the topology circuit is established,a capacitive current feedback method is proposed,and a specific harmonic current control strategy based on multi-synchronous rotating coordinate system is adoptd to improve the performance and stability of the system.Simulations and experiments verify the validity of the theoretical analysis and research results.
