摘　　要：以OMAP5912为硬件开发平台,采用加窗插值的快速傅立叶算法实现电网谐波参量的检测。使用该算法可以在非同步采样的条件下实现谐波参量(频率、幅值、相位)的准确测量,简化了硬件电路。本文重点阐述了检测装置的硬件整体实现方案及软件设计流程。在软件开发中使用DSP/BIOS操作系统,方便了开发过程,该检测装置具有很高的测量精度,很好的实时性。With OMAP5912 as a hardware platform, the algorithm of interpolating windowed FFI＂ is used for harmonics analysis in this paper. Using this method, the detecting equipment can realize the correct measurement for the various harmonic parameters （frequency, peak- to-p~ ,tk value, phase） under non-synchronization sampling situation, and the hardware design is si ~lplified. Main hardware design scheme and software flow chart of the system are importantly introduced. DSP/BIOS operating system is used for software development. The detecting equipment has good measurement accuracy and real-time performance.
