Numerical method for islanding the location of ground fault in the material based distribution system

Abstract

Nowadays the location of a ground fault and separating the fault segments are very complicated in the material based distribution networks because the reality to facilitate the fault current is really minute to be calculated. Considering the smart digital meters are installed in the distribution side voltage (11 kV) of the radial distribution systems through the advancement of the smart-grid. This paper presented an identification of fault location and islanding of fault segments using smart digital metering unit on the distribution network side. Generally, superior method is used to locate the faulted segments and the faulted negative sequence by connecting the association between measurement sets and distance of the fault. The proposed technology is experienced in India, a real-time 40-bus radial distribution system and the results provide that it is appropriate for a system with both inactive load demands. This technology does not need any management methods but it uses the wide-area measured data. Together with the breakers, the proposed methodology can locate and island the fault segments without disrupting the healthy distribution network process.
