    Abstract: A method for estimating fault location in an electrical power line system (PLS) is provided. The method includes receiving an observed signal caused by a real fault in the PLS. The observed signal is measured at a real observation point in the PLS. The real fault has occurred at one of two or more real locations in the PLS; accessing a library representing model signals between model guessed fault locations and a model observation point in a network model of the PLS; selecting a model GFL by: (i) calculating metrics for the model signals by processing the model signals with the observed signal, and/or (ii) selecting the model GFL corresponding to a highest calculated metric; estimating a fault location of real locations in the PLS based on a corresponding location of the selected model GFL; and sending the estimated fault location to an external management system.
