摘要随着科技和社会的不断发展进步，谐波问题越来越受到人们的关注，人们在对用电的质量和能效上有了更加高的要求。有源电力滤波器（APF）是解决谐波问题的电力电子器件，在提高电能质量方面扮演着极为重要的角色，其中并联型有源电力滤波器占据了主导地位。相对于三相有源电力滤波器，国内外对于单相有源电力滤波器的关注较少。然而，单相有源电力滤波器在实际使用中，有着很大价值，因此对单相有源电力滤波器投入更多的研究就显得尤为重要。86365

Abstract With the continuous development and progress of science and technology and society, more and more people pay attention to harmonic problems, it is the quality of electricity and energy efficiency have a more high demand。 Active power filter (APF) is a power electronic device to solve the harmonic problem，in the aspect of improving power quality plays a very important role, which held a dominant position in parallel active power filter。 Relative to the three-phase active power filter, less attention at home and abroad for single-phase active power filter。 However, single-phase active power filter in actual use, has a great value, so the single-phase active power filter to invest more research is particularly important。

In this paper, all aspects of the shunt active power filter have been studied in detail, mainly makes detailed discussion on the harmonic detection, and control of the harmonic only makes a brief analysis and discussion。

This paper first introduces the harmonic generation, harm and research significance, harmonic standards and mainstream harmonic suppression measures required by domestic and foreign。 Next, the paper introduces the current structure of the parallel active power filter, and gives a brief analysis of the working principle on the basis of the principle diagram。 Then,several methods of detecting harmonics are introduced, and the theory of instantaneous reactive power is analyzed, which verifies the correctness of the theory in the single-phase shunt active power filter。 After that, the method is improved and verified。 Next, the paper gives a brief introduction to the harmonic control method。 Finally, the Matlab simulation module is used to model the active power filter, and the harmonic detection method is verified, and the current after compensation is analyzed。 The simulation results show that the design of single-phase parallel active power filter in detecting harmonic reached the target。

Keywords: Single-phase shunt active power filter; Instantaneous reactive power theory; Harmonic detection
