A New Method for Interharmonic Detection via APES

Y. Ji and Y. Sun (PRC)


Interharmonic, APES, matched-filterbank, AC-DC-AC converter, characteristic order


The efficient techniques concerned with the problem of interharmonic detection have been of importance to modern power system , one of which is proposed in this paper based on the theory of Amplitude and Phase Estimation of a sinusoid ( APES ) spectral estimator which belongs to the matched-filterbank approaches. On the other side, an AC-DC-AC converter mode was built on Simulink, which can generate the signals embedded with characteristic order interharmonic. The experiment made demonstrate the efficiency of the above method.
