摘　　要：设计了一种以TMS320F2812为处理器,基于快速傅里叶变换(FFT)算法的谐波分析系统。FFT方法在电网谐波测量领域中是应用最为广泛的方法之一。但在采样过程中存在着频谱泄漏,影响测量结果的准确性。本文采用加Blackman窗的方法有效的解决了频谱泄漏问题。The harmonic -analysis systems for the TMS320F2812 processor is based on the Fast Fourier Transform （FFI＇） algorithms. The method of FFT is the most widely used in the field of power system＇ s harmonic - analysis. But the spectrum - leakage happen in the course of sampling and the accuracy of the measurement is not accurate. This paper has chosen to add the Blackman window which is effective to resolve the spectrum leakage.
