Resumen:
An evaluation of transmission line models is presented, appropriate for
electromagnetic transients studies for a pilot system diagnostic performance of the
Chest protection system. The data for preparation of the models were obtained from
treatment of the real physical and electrical characteristics of the known transmission
lines. Based on the processed data, models of transmission lines that make up the pilot
system were obtained, adopting distributed constant parameters, frequency dependent
parameters and the nominal PI. In order to evaluate the quality of the obtained models,
using ATP (Alternative Transients Program), were simulated faults with incidence angle
and location characteristics similar to the known real faults, comparing the results using
the coefficient of determination R². It was obtained a similarity of at least 94% of the
simulated signals and the real fault records, and the frequency dependent model
parameters presented better result.
