Abstract

This paper illustrates the application of continuous wavelet transform (CWT) for fault location in combined overhead line and cable distribution networks. The high frequency transient signals originated by faults are analyzed using CWT. The transient voltage waveform of faults is recorded at the certain measuring point. This method is based on the relationship between typical frequencies of the CWT signal energy and certain paths in the network passed by the travelling waves produced by faults. Due to this relationship, determination of the continuous frequency spectrum of fault transients in the form of signal energy is necessary and using characteristic frequencies directly related to the previously mentioned paths finally results in fault location. The IEEE 34-bus test distribution network is completely simulated in EMTP-RV and the CWT analysis of transient signals is implemented in MATLAB.
