Spectrograms to Distribute Power in Harmonic Signals
The paper proposes an improved approach to locating and categorizing harmonic signals in the power distribution by means of using spectrograms and time-frequency distribution (TFD) analysis. Spectrogram (occasionally referred to as temporal frequency representation ( TFR )) is an appropriate means of presenting signals in the joint time-frequency domain. Since the property of signals is recorded as the result of TFR, it can simply locate the detection and approximated information about the signals in the spectrum. The application of a rule based classifier and a set of thresholds referred to in the IEEE Standard is used to identify and categorize 200 individual signals with a range of harmonic features. The recommended approach is examined with the help of MAPE, and the outcomes suggest that the method is accurate. Moreover, the spectrogram is able to give hundred percent classification of harmonic signals. The proposed method to detect and classified harmonic signals in the distribution system has been proved to be accurate, fast, and cost effective.
