摘要：随着电力电子器件的大规模使用，电网的谐波污染日益严重，影响了电气设备的正常工作，因此消除谐波，抑制谐波污染刻不容缓。有源电力滤波器和无源电力滤波器各有其优缺点，而由两者构成的混合型有源电力滤波器可以取长补短，不仅可以降低谐波补偿系统的投资成本，而且可以提高谐波补偿系统的性价比。所以对混合型有源电力滤波器系统的研究具有重要的现实意义。55446

Abstract：With the large-scale use of power electronic devices, harmonic pollution of power systems becomes more and more serious, thus eliminating the harmonic, curbing harmonic pollution brook no delay. The Active Power Filter (APF) and Passive Filter (PF) has its own advantages and disadvantages. But the Hybrid Active Power Filter (HAPF) composed of Passive Filter and Active Power Filter can have their advantages and eliminate their disadvantages, not only can reduce investment costs of the harmonic compensation system but also can improve the ratio of price and performance in the system. So the study of HAPF is of important practical significance.
Firstly, this paper introduces the harmonic generation, hazards and governance, and then analyzes the working principle and classification of passive filter, active power filter and hybrid active power filter, compared the advantages and disadvantages for each kind of filter. Secondly, it introduces several harmonic current detection method and compensation harmonic current control strategy. Finally, using MATLAB simulation of the hybrid active power filter model. The simulation results show that the compensation characteristics of hybrid active power filter design and the filtering effect is very good, and verify that the study of the hybrid active power filter is effective and feasible.
Keywords: harmonic, hybrid active power filter, MATLAB simulation
