European Smart Grid Outlook

Down-Line Distribution Automation

IMR number:11-1502Pagination: pagesPublication date:May 2009Price:1.900,00 €
 
Description

European network operators always do a lot to improve the bottom line of energy delivery (e.g. remote control of line reclosers, monitoring and control of medium voltage feeder equipment) but there are challenges ahead. Regarding the automation of devices outside the substation fence (i.e., out on the feeders themselves) an assessment and opportunity screening shows room for improvement for such a down-line distribution automation approach (e.g. automated feeder switches and automated Fault Location, Isolation and Supply Restoration solutions). Some European network operators that are at the forefront have already installed one or more reclosers down-line from the medium voltage substation along selected feeders.
