Distribution network automation (DAS, Distribution Automation System) realizes the automatic control, fault detection, fault isolation, and restoration of power supply functions of the distribution network by integrating advanced automation equipment, communication technology . istribution network is a user oriented window for power enterprises. Feeder automation (FA) is an important part of intelligent power distribution, which can monitor line operation, find line faults in time, diagnose fault areas quickly, isolate faults and restore power supply in non fault areas. The Smart Grid policy requirements as outlined in Energy Independence and Security Act (EISA) of December 2007 will increase the need for Distribution Automation, and therefore a better understanding of the benefits and challenges of Distribution Automation for all of its stakeholders. This paper analyzes FA from the aspects of FA realization mode and. The U. Department of Energy's Modern Grid Initiative1 articulates seven key characteristics that identify and measure progress via the implementation of the smart grid. They include enabling active participation by consumers; new products, services and markets; the ability to accommodate all.
