摘要
针对有源滤波器的谐波检测算法进行研究,采用了实时性较高的基于瞬时无功功率的ip-iq法来进行谐波检测,分析了算法及二阶Butterworth低通滤波器的数字化设计,并以TMS320F2812型DSP为核心,搭建试验平台,具体分析了实验的软、硬件设计,给出部分硬件电路图,画出了软件流程图,完成谐波检测实验,并取得良好的实验效果。
This paper is aimed at the harmonic detection method of Active Power Filter, uses real-time high instantaneous reactive power based on ip-iq method for harmonic detection, analysis of the algorithm and second-order Butterworth low-pass digital filter design, and type TMS320F2812 DSP core, build test platform A detailed analysis of the experimental software and hardware design, and gives some of the hardware circuit diagram, draw a flow chart of software to complete the harmonic detection experiments, and obtained good experimental results.
