Technical and Economic Evaluation of Implementing Outage Management System in Urban Distribution Systems in Iran

Faults in MV systems are the cause of almost 70 percent of outages in power system. By using suitable outage management methods, amount of power outages will be reduced in large extent. In Iran, traditionally outage management system was conducted by trial and error methods and relied on operators’ experience. The ever-increasing expansion of distribution networks has made it impossible to use traditional outage management systems. Outage management systems depend upon load type, load sensitivity, network type, amount of accumulation of load and population, and being rural or urban network. In this paper, at first a technical assessment for implementing outage management methods in distribution systems of Iran is carried out. An economic assessment of implementing outage management system in urban distribution systems of Iran with dense population is conducted. For this purpose a sample network of Afsarieh area of Tehran has been chosen.
