Genetic algorithm based fault locator scheme for three-terminal transmission lines using asynchronous measurements

This paper proposes a simple and accurate fault location scheme for three-terminal transmission lines using unsynchronized measurements. The algorithm presents the fault location procedure as a Genetic Algorithm based optimization problem with a lower dimensionality compared to those proposed in literature. Data synchronization and fault location procedure is carried using post-fault data samples to increase accuracy and is independent of the reference selected. The algorithm was extensively tested for all major fault types and the results prove the efficacy of the proposed scheme.
