Abstract

With the development of technology, the power quality detect devices become more and more powerful and the measure accuracy increase quickly. This paper analyses frequency and harmonics signal of power system based on the theory of all-phase FFT spectrum by FPGA which has powerful processing function. All-phase time-shifting phase difference correcting spectrum algorithms is used to correct the measurements of power parameters quickly. The paper analyze the real-time data of power harmonics and frequency with high accuracy, the precision of frequency is 10 which can detect harmonic component under 20 degree correctly.

Keywords: All-phase FFT Harmonic Analysis FPGA
