Harmonics and interharmonics spectral analysis by ANN

2016 Conference on Precision Electromagnetic Measurements (CPEM 2016), 2016
In this paper we present a new method based on ADALINE artificial neural networks (ANNs) for the spectra analysis and frequencies estimation of signals with harmonic and interharmonic content. First tests indicate that the method is able to obtain high accurate results without any information about the signal under analysis.

A new precise measurement method on interharmonics

2009 IEEE Intrumentation and Measurement Technology Conference, 2009
For the signal containing the inter-harmonics, if the sample number is not equal to integer times of the signal period, the spectral leakages will occur in harmonic analysis based on DFT and affect the measurement accuracy. To improve the accuracy, different from other correction methods in which the long-range leakages are reduced by windowing the ...

Analysis of Wavelet Transform for Interharmonic Measurement

Advanced Materials Research, 2013
Fast and accurate measurement of interharmonic is a difficult problem. Fourier transform is widely used but it is not suitable for real-time application. Wavelet transform has better real-time performance, but its accuracy needs to be improved, so the paper studies the performance of wavelet transform for interharmonic measurement.

Interharmonics-recommended updates to IEEE 519

IEEE Power Engineering Society Summer Meeting,, 2003
Over the last several years, much work has been done in the field of interharmonics. International standards organizations have defined the terminology, organizations and individuals have published significant work on their impacts on equipment and humans, and some guidelines for allowable levels in power systems have been proposed.
