Resumo:
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.
