Research on Fault Cause Identification Method for Transmission Lines Based on Distributed Transient Traveling Waves

Transmission line corridors traverse complex terrain and climatic conditions, making them prone to fault trips caused by natural factors. These faults severely threaten the safe and stable operation of the power grid as well as equipment reliability. Rapid, accurate, and reliable fault identification technology is crucial for improving line operation and maintenance. Distributed fault monitoring devices can capture traveling wave signals with distinct characteristics at the moment of a line fault, laying a foundation for accurate fault cause identification.
