Overview

Randomized trial demonstrates enhanced fault identification accuracy in distribution networks, suggesting improved reliability.

Key Points

  • This research aims to develop an integrated method for accurate identification and location of single-phase ground faults in distribution networks.
  • Fault type identification using sequence component characteristics prior to line selection.
  • Feature construction based on variational mode decomposition optimized by the Sparrow Search Algorithm.
  • Utilization of a single-ended fault location method based on wavelet transform modulus maxima.
  • Achieved fault-line selection accuracy of 98.4%.
  • Location error for a 100 km line is less than 1.673%.
  • SVM-based approach outperforms conventional fuzzy theory methods under complex fault scenarios.
