【Abstract】 Applying the frequency\|domain representation of the complex signals in a three phase system, a harmonic detection method based on the in phase correlation filtering was put forward in this paper, which can be used to detect effectively the generalized harmonics in the three phase system except the fundamental of positive sequence. The simulation about the harmonic detection of a three phase cycloconverter fed a.c. excited generator verified the effectiveness of the method.更多还原
