Abstract

This paper presents a new numerical algorithm for blocking autoreclosure during permanent faults on overhead lines. It is based on one terminal input data processing and it is derived in time domain. The fault nature (arcing or arcless fault) is determined from the arc voltage amplitude estimated using the least squares error technique. The faulted phase voltage is modeled as a serial connection of fault resistance and arc voltage. The new approach does not require the line zero sequence parameters as input data and the algorithm is derived for the case of the most frequent single-phase to ground unsymmetrical fault. The results of algorithm testing through computer simulation and under laboratory conditions are given. The influence of remote infeed, fault resistance, network topology and other factors are investigated and systematically presented.
