SUMMARY:

This doctoral thesis presents an interpolation-based solution that allows the application of the traveling wave (TW)-based double-ended fault location algorithm even using sampling rates lower than those typically considered as a requirement for classical approaches. Two phasor (PH)-based and one TW-based fault location methods are compared with the proposed technique and applied through Alternative Transients Program (ATP) fault simulations in a 500 kV/60 Hz Brazilian double circuit series-compensated transmission lines with high-voltage direct current lines (HVDCs) and static var compensators (SVCs) in the vicinity. The results show that the proposed interpolation-based technique is reliable and suitable for TW-based fault location using data records with sampling rates lower than those used in commercially available equipment. Moreover, its accuracy is comparable to classical TW-based fault location solutions, revealing its usefulness for practical application when only traditional digital fault recorders (DFRs) are available.
