Analysis to Automation Design Scheme for County-level Distribution Network

Combining with county distribution power grid planning of 12th Five-Year Plan in Inner Mongolia, taking one certain county as an example, one practical construction planning suitable for county level distribution automation has been put forward: combined model between feeder automation and a small system of power distribution monitoring and management. This model starting from the practical and economic point of view, automatic to make fault isolation, to restore power supply to healthy area and to monitor operation of distribution power grid, which can realize shortening outage time and improving power supply reliability purposes.
