Determining optimum location of automated switches in distribution network

The main function of power system providing the electrical energy for costumers with a proper ldquoreliabilityrdquo. So the automation on the power system is an important parameter due to its effect on reliability. Automation can greatly enhance distribution-network reliability by speeding up service restoration and thus significantly reduce customer-outage time. The automation system has several parts in the distribution network. The switching is one of the important part in this system. The number of switching and its configuration have a major effect in increasing the reliability. In this paper an approach for the best configuration of the ldquoautomation switchesrdquo in the distribution system, is studied. First the calculation of reliability is presented, then the influence of automation on reliability is described in detail.Finally the best configuration of the switches are obtained using a user writer code.
