| The objective of this project is to help utilities implement or prepare to implement a fault locating system. This report addresses a number of problems and questions that utilities encounter before or during their implementation process. This report starts with a literature review of distribution fault-location methods and utility fault location systems. Several different systems were evaluated, including those utilized by Progress Energy Carolinas, Con Edison, San Diego Gas & Electric, and Hydro Quebec. The performance of different fault location algorithms was evaluated using monitoring data. This monitoring data is a large library of field data that was collected from the utilities. Different fault location approaches on different types of distribution circuits were evaluated. System integration issues are a challenge when implementing a fault location system, integrating communications from monitoring, and integrating circuit and mapping data. In addition, a user interface for a dispatcher must be implemented using either a web-type interface or by integration of fault-locating results into the outage management system (OMS) and/or GIS mapping systems. Keywords: Distribution fault location, reliability, distribution monitoring system, power quality |
