Abstract

This is Part II of a two-part paper which presents a methodology for fault location and isolation and service restoration (FLISR) for power distribution grids. The Criterion 1 discussed in Part I is adapted to locate faults when distributed generations (DGs) exist. For DGs with larger capacity, faults can be located by coordinating the reclosing of circuit-breakers and cutting off DGs. Two advanced schemes for service restoration are presented. The modeled service restoration has priority. The service restoration with minimum load shedding assures a solution if the other three schemes fail. An algorithm of switching sequence to minimize the interruption cost is proposed. The proposed approaches to FILSR have been imbedded in 26 power distribution automation systems of 10kV grids since 2013, and have been proven to be a great success.
