摘　　要：EMD算法是一种有效的电网谐波检测方法,针对谐波检测和EMD算法的特点,给出一种基于Blackfin533 DSP的硬件实现方法。介绍了EMD算法的基本原理,给出了基于DSP的EMD算法的软件实现流程。并根据EMD分解结果,求出了各次谐波的瞬时幅度、相位和频率。EMD algorithm represents an effective method for the detection of harmonic in power system. Depending on the characteristics of harmonic detection and EMD algorithm,a hardware method of Black-fin533 based on DSP was given.After the introduction of the basic principle of EMD algorithm,EMD al-gorithm software process was presented based on DSP.On the basis of EMD decomposition results,the instantaneous amplitude,phase and frequency of the harmonic test signal were calculated.
