Research And Application On Feeder Automation Technology Base On The Distribution Station

Feeder Automation is the core function of distribution automation, can effectively improve distribution network reliability. Along with the urban and rural distribution network transformation and the further promotion of distribution automation applications, feeder automation gradually entered a stage of normalization operation. As a starting point, this paper do its research to satisfy the demand of feeder automation.This paper focuses on modeling and implementing methods of feeder automation on distribution station, put forward a series of performance optimization design on network and real-time database, and propose a determination method of the accident and a reliable confirm method for the remote control. Then base on graph theory, this paper gives the mathematical model of feeder automation, and algorithm design of fault location, fault isolation and network reconfiguration. Especially put forward line load balanced handing strategy on the restoration of power supply with multiple standby powers; and finally carry on the module design and development on feeder automation subsystems.Distribution automation pilot application in Wuhan as background, conducted fault simulation tests on the distribution station, verified the algorithm of fault location,fault isolation and network reconfiguration.
