Series fault arc detection based on Stacking model fusion

Abstract： Aiming at the problems of missed detection and false detection due to different arc combustion levels and current distortion levels in low-voltage AC distribution networks, a time-domain arc fault detection method based on Stacking model fusion is proposed. The time domain features are extracted from the loop current, and the time domain features are formed into a feature matrix to optimize the parameters of the machine learning algorithm decision tree and the integrated learning algorithm random forest. Finally, the integrated learning algorithm is used as the base learner instead of the machine learning algorithm to build a low-voltage AC fault detection model through Stacking model fusion. The experiment collected a total of 96 970 groups of parallel currents of six electrical appliances. The results show that compared with non-integrated algorithms and other integrated algorithms, the proposed method has higher accuracy, precision and F1 index, and its model is more robust.
