摘要
随着电力电子技术的飞速发展,大量的电力电子变流装置越来越广泛的应用到厂矿、
交通、通讯及家用电器中,在电网中产生大量的谐波电流,对电力系统造成严重危害。因
此,抑制电网中的谐波、提高用电装置的功率因数已成为电力电子技术、电气自动化技术
及电力系统研究领域所面临的一个重大课题。
本文本课题以带电阻负载的三相整流桥为谐波源,采用并联型有源电力滤波器对其进
行谐波补偿。采用基于瞬时无功功率理论的 ip-iq 运算方式来研究并联型有源电力滤波器的
谐波检测,并选择瞬时值比较控制算法进行补偿;采用 MATLAB 进行了仿真研究,并验证
了所用方法的可行性;在理论研究的基础上,本文选用 TMS320 F2812型号的 DSP 芯片构成
并联型有源电力滤波器控制系统的核心,设计制作了相关外围电路及功率电路;同时进行
了软件的设计,最后制作了一套实验室样机系统。

STUDY ON THE CONTROL SYSTEM OF ACTIVE POWER
FILTER BASED ON DSP
ABSTRACT
With the rapid development of power electronic technology, a large number of electronic
power conversion devices are widely applied to factories, mine, transportation, communications
and home electrical appliances, there are a lot of harmonic currents in power grids, causing
serious damages to the power system. So, restraining harmonics and improving power factor of
the electrical equipments has e an important subject of power electronics technology,
electrical power systems and automation technology.
In this paper, the uncontrollable three-phase rectifier with resistance load was selected as
the harmonic source and parallel APF (active power filter) was used pensate the
harmonics, the ip-puting methods based on the instantaneous reactive power theory was
selected to study the harmonic detection of the active power filter, the control
parison of the instantaneous values was selected pensate the harmonics.
After the theory was confirmed, the software-MATLAB was used to simulate it and verified the
feasibility of it.
Based on theory research, the dsp-TMS320F2812 was selected as the CPU of the control
system of the parallel APF and the related peripheral circuits and power circuits were designed;
At the same time the software was designed, and finally a laboratory prototype was achieved.
