Abstract
The invention relates to a transient based method for identifying faults in an electric power transmission and/or distribution system () having at least one current transmission line (L, L, L) comprising the following steps: —generation of a physical model of the at least one current transmission line (L, L, L), the physical model depending on the fault parameters and describing the behavior of voltage and/or current transients due to the fault in the at least one current transmission line, fault parameters comprising a fault location parameter on said current transmission line (L, L, L) and a fault impedance parameter, —measurement of voltage and/or currents evolution at least at one specific location in the said power system (), —iterative simulation of the voltage and/or current evolution by the physical model at the measurement point with a set of fault parameters where at each step of iteration, simulated and measured voltage and/or current evolutions are compared and the set of fault parameters is adapted according to a convergence criterion, —identification of a fault with its fault parameters when convergence of the measured voltage and/or current evolutions and simulated voltage and/or current evolutions is reached in a limited number of iterations.
