Design of an economical and technical distribution automation system

Continuity of energy supply and outage reduction is one of the main goals of the distribution companies. In this regard, automation of distribution networks is one of the most important duties to reduce the amount of outages. Crucial parts of the Medium Voltage (MV) feeders shall be monitored and controlled by Distribution Automation (DA) system. So the main issue in designing this system is positioning and its required facilities in those points. Totally, systems include economic justification will meet uninterrupted work and services. Therefore, in the process of designing an automation system having economic justification while the technical goals should take into consideration too. For this purpose, this paper tries to present accounting method for determining areas of automation based on optimizing cost/benefit function.
