Abstract

In this paper, the application of S-transform for fault location in distribution networks has been considered. The S-transform is discovered to be applicable in transient based fault location in distribution networks. This technique is a expansion of Wavelet transform method and is based on a moving and scalable localizing Gaussian window. Taking into account this fact that the signal energy of faults has high amplitude around certain frequencies, the fault location can be identified considering the relationship between these frequencies and so-called path characteristic frequencies related to the fault traveling waves. The transient voltage signal energy is calculated using S-Transform. In order to demonstrate the effectiveness of the proposed method, conventional distribution networks and combined system (with overhead lines and underground cables) as two case studies have been evaluated. The IEEE 34-bus test distribution network is simulated in EMTP-RV software and the relevant S-transform analysis is carried out in MATLAB coding environment.
