Robust transmission line fault classification using wavelet multi-resolution analysis.

Highlight: [•] Power system model for transmission-line fault classification fed from both ends. [•] Fault classification algorithm for doubly fed EHV transmission line using wavelet MRA. [•] The synchronized fault currents passed through wavelet MRA technique for determining the sixth level detailed coefficients. [•] Sag1, Sbg1, Scg1, Sag2, Sbg2 and Scg2 are used to classify the type of fault occurred in the transmission line. [Copyright &y& Elsevier]
