Knowledge-based system for distribution system outage locatingusing comprehensive information

摘要

This paper presents a knowledge-based system (KBS) designed tonlocate distribution system outages using comprehensive data fromncustomer trouble calls, a wireless automated meter reading (AMR) system,nand distribution supervisory control and data acquisition (SCADA). Thenalgorithm uses the on-demand read capability of a wireless AMR system,nwhich allows the utility to communicate directly with the meterncontrollers. The algorithm of the developed KBS has two major parts: annoutage escalation procedure and meter-polling procedure. The escalationnprocedure involves searching for the outage region according to thencomprehensive outage information. The meter-polling procedure includesndesigning the meter-polling schema and confirming the outage locationsnbased on the meter polling results. The algorithm was designed to handlenboth single outage and multiple outage situations. The expert systemnshell G2 was used as the development tool
