Abstract
© 2015 Taylor & Francis Group, London. Protection algorithms are related to what provides the highest accuracy in location of faults produced by lightning strokes on transmission lines. Thus, in this paper a novel methodology for lightning stroke location based on impedance estimation in new coordinate axes is presented. Principal Component Analysis (PCA) is used to project the voltage and current signals with data windows of. cycles onto new coordinate axes, corresponding to the Principal Components (PCs) subspace. Then, these new voltage and current values are used to calculate the apparent impedance in the PCA subspace. This projection shows a relation between the new impedance value and the point of impact along transmission lines. Based on this, two functions that localize the flash point produced by lightning strokes are found. Results show that the proposed methodology for location of lightning stroke on transmission line presents satisfactory results.
