摘要：

Dominant harmonic sources can be located by determining the direction of harmonic power flow at various points in a power system. Multi-channel data acquisition systems and commercially available digital signal processing software packages make the determination of harmonic power flow possible provided the limitations of the analysis techniques are understood. The paper describes how data from a typical acquisition system may be processed using the Fast Fourier Transform and discusses possible errors and how to avoid them using techniques such as skewing correction and windowing. Guidelines on the practical application of the transform in analysing measured data are presented and may be applied in most harmonic analyses.
