A Machine Learning Based Tool for Voltage Dip Classification

The paper presents a Machine Learning-based tool for making the ex-post analysis of voltage dips (VD) more automatic and effortless. The tool takes as input the full waveforms associated with voltage dips occurring in Italian MV networks and recorded by the QuEEN monitoring system implemented by RSE.

The first tool was developed to classify events based on their HV/MV origin, since utilities will only be responsible for events due to failures occurring in their own networks; it uses Kalman Filter and Support Vector Machine (SVM) self-tuning to extract VD characteristics and classify events, respectively.

On the other hand, the second tool, based on end-to-end Deep Learning, has been developed to distinguish between ‘true’ and ‘false’ voltage dips (VDs); it uses a Convolutional Neural Network (CNN) whose first layers are responsible for feature extraction while the last layers perform event classification.
