Abstract :
A networked power quality detection system was proposed for the existing high-order harmonic in the power grid and the quality parameters need for long-term detection and analysis in real time. Using fast FFT carried on data processing for the voltage and current signals synchronize sampled by the data acquisition card to realize the display and analysis on power quality parameters. Experimental results show that the system can long-term detect and analysis the power quality parameters in real time, and the number of harmonic analysis can reach 1024 times and the error of phase analysis is very small.
