Comparação entre métodos de localização de faltas em linhas de transmissão com compensação série capacitiva.

Abstract

Transmission lines (TL) enable the interconnection of electricity generation to its final destination, so studies that aim to continue this transmission are of fundamental importance. Currently, it can be found in the literature a wide range of techniques that allow the location of faults in transmission lines from different analysis and concepts, each one with their respective capabilities and limitations. Using traditional methods found in the literature, such as methods based on the traveling waves theory and methods based on the analysis of the fundamental frequency components, a comparative analysis was performed to identify the positive and negative aspects of each technique. To validate the comparison between the methods, using the MODELS language of the ATP (Alternative Transients Program) and MATLAB®, fault simulations were performed to identify in which situations each method has been shown to be more convenient and in what situations its use should be avoided. Moreover, an analysis of the influence of capacitive series compensation in the transmission line was performed, using data from a real transmission line.
