Reliability assessment of smart distribution system and analysis of automatic line switches.

摘要

Electric Power reliability is a major concern of any utility company. Although the distribution system is getting advanced, reliable energy at a cheaper cost is still a big concern. Power utility companies are trying to provide reliable energy through many possible ways. One of the possible solutions is use of automatic switches.;Power utility companies are using automatic switch called IntelliRupter RTM for automatic fault detection, isolation and service restoration. It has been the biggest achievement in improving reliability so far. However, such automation is very costly. It needs proper planning for installation of such devices so that the utility company can make the most benefit at optimal cost.;The main objective of the study is to compute reliability of the distribution system using Failure Mode and Effect Analysis method. Also, it presents step by step economic analysis to determine optimum number and location of automatic switch fulfilling reliability and economic constraints.
