Harmonic detection system for active power filter based on FPGA

In this paper,harmonics detection methods based on the instantaneous reactive power theory of power system was discussed.The filter design was improved according to the characteristics of power system harmonics,and harmonics detection system based on FPGA was designed.Because of the integral algorithm lowpass digital filter,computational speed of FPGA was greatly increased.Experimental results show:that the connection between synthesis area restriction and speed restriction can be flexibly optimized because...
