Fault Location Detection Using CEEMD and Two-Terminal Traveling Wave Ranging

This study proposes an approach for accurate fault localization in power transmission lines by integrating two-terminal traveling wave ranging with complementary ensemble empirical mode decomposition (CEEMD). The two-terminal traveling wave method is widely recognized for its effectiveness in fault detection but suffers from reduced accuracy in the presence of noise and signal distortion. In the proposed method, raw traveling wave signals are first transformed using the Karrenbauer transformation to obtain α, β, and zero-sequence components. CEEMD is then applied to decompose these components into intrinsic mode functions, effectively filtering noise and isolating fault-related features. The integration of CEEMD with traveling wave analysis enhances fault location accuracy and provides a reliable framework for power system fault detection. The method is validated using the IEEE 5-bus system, demonstrating improved robustness and performance.
