Methodology for Designing a Fuzzy Resolver for a Radial Distribution System Fault Locator. (December 2005) Jun Li, B.Eng.; M.Eng., Xi’an Jiaotong University Chair of Advisory Committee: Dr. Karen L. Butler-Purry Dr. B. Don Russell The Power System Automation Lab at Texas A&M University developed a fault location scheme that can be used for radial distribution systems. When a fault occurs, the s...

This paper presents a technique for diagnosis of the type of fault and the faulty phase on overhead transmission line. The proposed method is based on the multiresolution S-transform and Parseval’s theorem. S-transform is used to produce instantaneous frequency vectors of the voltage signals of the three phases, and then the energies of these vectors, based on the Parseval’s theorem, are utiliz...

A new scheme to enhance the solution of the problems associated with Transmission line protection with Statcom connected is presented in this paper. The fault detection is carried out by using energy of the detail coefficients of the phase signals and artificial neutral network algorithm used for fault type classification and fault distance location for all the types of faults for 220 KV transm...

The issue of fault location received extensive concern in the field of telecom network management. The data mining approaches are introduced to extract clues from the telecom alarm data for fault location. Aiming at the key problems in telecom data mining. We have made a comprehensive analysis on the telecom network and its data as well as the fault propagation some important characteristics ar...
