Classification of the Type of Harmonic Source Based on Image-Matrix Transformation and Deep Convolutional Neural Network

Abstract: The classification of harmonic source types is a necessary step to alleviate harmonic pollution. This study proposes a method for the harmonic source classification based on 2-D image-matrix transformation (IMT) and deep convolutional neural network (CNN). The method firstly converts the V-I waveforms of different harmonic source types into a matrix by IMT, which was then applied to express the V-I waveform of each harmonic source as an input CNN model. Thereafter, features were extracted automatically from th… Show more

“…Besides, the proposed method has better detection accuracy for the IEEE‐69 bus test system. In this paper, the best classification accuracy for nineteen classes is 99.89%, and its detection time is 0.028432 s. Also, in [12, 17, 19, 21], the detection accuracy and the detection time of the signals contaminated with different noise levels were not studied. The papers [10–13] use multiple‐point measurement methods which have drawbacks such as high computational burden and high memory storage.…”

“…Nevertheless, gathering information from both voltage and current is time-consuming and different harmonic sources, such as inverter-based DGs were not considered. Two-dimension image-matrix transformation and deep convolutional neural networks were used in [17] to classify the harmonic sources. The authors in [18] presented a method based on the artificial neural network (ANN) for harmonic source identification.…”
