Abstract

Electric power distribution systems are responsible for delivering the electrical energy from the bulk power systems to the customers. Radial operation, aging infrastructures, poor design and operation practices and high exposure to environmental conditions have caused the electric power distribution systems as the main contributor to the system reliability problems. Generally, about 80 to 90 percents of the customer reliability problems originate from the electric power distribution systems. In this paper, the effect of two automation intensity levels on the reliability of radial distribution system is compared with system without automation. Partial automation and complete automation are considered. The effects of automation intensity levels on the outage time of the components considering the sequence of fault diagnosis activities that will take place from the initiation of fault to the service restoration and the reliability of the system is measured in terms of SAIDI, CAIDI, SAIFI and ENS. These reliability indices are calculated for the Roy Billinton Test System (RBTS) Bus2 using Failure Modes and Effects Analysis technique.
