Exploring the use of Shapelets in Traveling Wave based Fault Detection in Distribution Systems

Biswal, Milan; Pati, Shubhasmita; Ranade, Satish J.; Lavrova, Olga; Reno, Matthew J.

The application of traveling wave principles for fault detection in distribution systems is challenging because of multiple reflections from the laterals and other lumped elements, particularly when we consider communication-free applications. We propose and explore the use of Shapelets to characterize fault signatures and a data-driven machine learning model to accurately classify the faults based on their distance. Studies of a simple 5-bus system suggest that the use of Shapelets for detecting faults is promising. The application to practical three-phase distribution feeders is the subject of continuing research.
