The fault identification prior to reclosing is based on optimized artificial neural network associated with standard Error Back-Propagation, Levenberg Marquardt Algorithm and Resilient Back-Propagation training algorithms together with Taguchi's Method. The algorithms are developed using MATLAB software. A range of faults are simulated on EHV modeled transmission line using SimPowerSytems, and the spectra of the fault data are analyzed using fast Fourier transform to extract features of each type of fault. For both training and testing purposes, the neural network is fed with the normalized energies of the DC component, the fundamental and the first four harmonics of the faulted voltages. The developed algorithm is effectively trained, verified and validated with a set of training, dedicated testing and validation data respectively. © 2009 IEEE. date: 2009 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-65949118488&doi=10.1109%2fICCET.2009.171&partnerID=40&md5=2a8f020ea4d6cff2b0a70b5ed1d3a08e id_number: 10.1109/ICCET.2009.171 full_text_status: none publication: Proceedings - 2009 International Conference on Computer Engineering and Technology, ICCET 2009 volume: 2 pagerange: 151-155 refereed: TRUE isbn: 9780769535210 citation: Desta Zahlay, F. and Rao, K.S.R.
