1、随着电力电子技术的快速发展，电力电子装置在各行业领域均得到广泛应用，可由此带来的电网谐波和无功等问题却日益严垂，这对电力系统的安全、稳定及有效运行造成了极大的威胁。因此以谐波治理和无功补偿为目的的屯力屯子装置应运而生。论文结合电力电子技术、计算机控制和电力系统等交叉学科设计了基于DSP控制的并联型有源电力滤波器（APF）。在查阅量中英文相关资料的基础上，阐述了谐波的产生、危害及其治理必要性，介绍了APF的发展、分类及工作原理，并详细说明了APF主电路的设计方法以及其主要器件的选取和参数的确定。之后揽各谐波电流的检测方法，重点分析了基于瞬时无功功率理论的p-q以及ip・iq谐波电
2、流检测法。此外,还着重研究了APF的控制策略，包括补偿电跟踪控制和直流侧电压控制，并最终选定各自适合的控制方式。论文在进行以上分析、研究、的基础上，对APF系统进了总体设计，进行了APF系统主控板、DSP核心板、采样电路等硬件电路设计。软件上，设计主从系统各部分程序流程图以及相应的软件编程。关键词：有源电力滤波器谐波抑制瞬时无功功率理论THEDESIGNOFACTIVERFILTERAbstractWiththerapiddevelopmentofpowerelectronicstechnology,powerelectronicequipmentshasbeenwidelyu
