Abstract:
The price that customers pay for electric energy is determined by cost of generation, transmission and distribution parts. In Practice all customer have main concern about reliability of electric energy, because of it’s major effect on different aspect of life. Although customers are interested to have fully reliable service, but power companies are aware that it is impossible to achieve this goal from technical and economical aspect. The utilities and customer benefits can be achieved through minimization of the total investment cost of network, while improving the reliability and quality of electric service. This also requires to minimize the customers service interruption time. To meet the customer satisfication in distribution systems, the distribution automation system is employed. To implement the distribution automation system, the application of modern automated equipments is inevitable. In addition the additional expenditure should be evaluated. In this thesis two type of devices: the fault indicators and the load break switches; are studied to find their optimum numbers and locations, by employing binary particle swarm optimization in order to minimize the total cost
