New concept for fault location in series- compensated parallel lines is presented. The developed one-end fault location algorithm offsets the series compensation and the reactance effects as well as takes the countermeasure for the mutual coupling between parallel lines. Its distinctive feature relies in no requirement of the impedance data for the equivalent systems behind both the line terminals and for the possible extra link between the substations. Moreover, complete avoiding of pre-fault measurements is provided. The sample fault location cases for the fault data obtained from versatile ATP-EMTP simulations are included and discussed.
