Abstract: With rapid development of the national economy and power industry, the electricity loads are becoming complicated and diversified. The harmonic pollution has been become a great problem to endanger electric network and affect economical safety operation of other utilization equipments. This paper emphasized on some kinds of the latest detection methods for power systems harmonics. Harmonic restraint methods were compared and analyzed, and especially active power filtering and reactive power filtering were discussed. It is good reference to the detection and restraint of power systems harmonics, and helps in practical work.

Keywords: Harmonic; Detection; Restraint; Wavelet; FFT; Active power filtering; Reactive power filtering
