An Accurate Classification Method of Harmonic Signals in Power Distribution System by Utilising S-Transform
Abstract: This paper presents
an accurate classification method of harmonic signal in power distribution
system by using S-transform (ST). ST has
a capability of representing signals in jointly time-frequency domain and known
as time frequency representation (TFR). The spectral parameters are estimated
from TFR in order to identify the characteristics and to classify the harmonic
signals. The classification of harmonic signals with the utilization of pattern
recognition approach which is rule-based classifier of 100 unique signals is
according to the IEEE standard 519:2014. The accuracy of the proposed method is
determined by using MAPE and the results proved that the method provides high
accuracy of harmonic signal classification. Additionally, S-transform also
gives 100 percent correct classification of harmonic signals. It is proven that
the proposed method is accurate in detecting and classifying harmonic signals
in the distribution system.
