摘　　要：介绍了一种同步旋转坐标系的谐波提取方法,并同时辅以无限脉冲响应数字滤波技术及时间延迟补偿策略。通过Matlab仿真研究并设计,实现了以DSP为核心处理器的有源电力滤波器(APF)数字化提取方案。经过仿真试验分析和工程验证,证明了该方法的有效性和准确性。Active power filter（APF） ＇ s compensation performance depends on the system＇ s compensation current extraction algorithm and the main power inverter＇ s control strategies. This paper presented an infinite impulse response of digital filter technology and the time delay compensation strategy combined with a harmonic and reactive extraction algorithm on synchronous rotating coordinate system. Simulating through Matlab, the paper designed and implemented the digital extraction program on APF with DSP as the core-processor. The method is proved to be effective and accurate by experimental analysis and engineering verification.
