Series Arc Fault Recognition Based on Multi-feature Extraction and GA_SVM
To detect the series arc fault under the condition of 115V/400Hz power supply, the even harmonic sum and kurtosis index analysis is performed on the current signal before and after the arc fault in the point contact experiment.The selected method covers the characteristics of the time and frequency domains of the signal.The even harmonic sum and kurtosis values are extracted as the features for discriminating the arc fault, and the arc fault is identified by the support vector machine optimized by genetic algorithm (GA_SVM).Compared with the recognition accuracy of a single feature, the accuracy of the recognition after combining the features into a two-dimensional matrix combination is further improved.The result shows that the correct rate reaches 98.5714%.
