Continuous-Wavelet Transform for Fault Location in Distribution Power Networks: Definition of Mother Wavelets Inferred from Fault Originated Transients

none5The paper presents a fault location algorithm for distribution networks based on wavelet analysis of the voltage waveforms of the traveling waves recorded at a bus during the fault. In particular, the proposed procedure implements the continuous wavelet transform combined with the use of mother wavelets inferred from the fault-originated transient waveforms. The performance of the proposed algorithm are analyzed for the case of the IEEE 34-bus test distribution system and compared with those achieved by using the Morlet mother wavelet.mixedA.
