Abstract
This letter presents a novel non-iterative impedance based two-terminal fault location algorithm with unsynchronized terminals. The novelty of this method lies in the fact that it is non-iterative, does not require signal alignment, are independent of fault classification, suitable for both transposed and untransposed lines with distributed line model. Several results of simulations on standard and practical data of Power Grid Corporation of India Limited (PGCIL) are presented. The test results verifies the validity and accuracy of the developed fault location algorithm.
