  • This paper introduce an algorithm for service restoration in electric power distribution systems. Power utility performs service restoration in order to restore out-of-service areas at fault. Developing effective service restoration program is a cost-effective approach to improve service reliability and to enhance customer satisfaction. The main objective in service restoration program is to restore as much load as possible by transferring de-energized loads via network reconfigurations to other supporting distribution feeders without violating operating and engineering constrains.

  • This paper introduces the additional remote monitoring and remote setting functions needed to operate the distribution automation system effectively. we compare the additional functions with the old functions. The remote setting of minimum trip value of fault indicator is an example of additional function. It saves time and line-man's power. Also this paper describes the data transmission flow diagram for operation of distribution automation system using wireless communication method.
