Recent years with the power electronic devices was widely used harmonic became one of the main factors of affecting power quality. This paper provided a design of DSP-based harmonic detector with the characteristics of real-time and high-precision. The adding Hamming window FFT (Fast Fourier transform) algorithm was used to analyze harmonic. This paper introduced the radix-2 FFT algorithm and the performances of Hamming window function and focused on the design of the system hardware and software. The final testing results showed that the adding Hamming window FFT has good harmonic detection performance and it can depict truly the signal singularity, clear the occurring time of interference and the degree of disturbance.
