Abstract

A rule based decision support (RBDS) system application to single-line fault detection in a delta-delta connected distribution system is described. The RBDS system is built from knowledge acquired through exhaustive simulation based on nonarcing type fault situations. It is primarily designed to detect the presence of a fault, to identify the faulted feeder and the faulted phase, and to classify the fault type. It is also designed to gauge the proximity of the fault to the substation and to assess the fault impedance. The RBDS system is tested with different sets of simulated data and proves successful in most cases
