The latest development of distribution automation technology is briefly treated and some existing problems in the construction of distribution automation are analyzed. A new technical scheme of smart distribution grid dispatching and control system is proposed

whose framework is based on the integration of distribution dispatching control

emergency repairing technology and information integration technology. The key techniques in practical application are discussed

including distribution network large data acquisition

feeder automation

distribution geographic information system (GIS) demonstration and advanced application algorithm adapted to the characteristics of distribution network. In consideration of the influence of new energy access to distribution network

improvement and adjustment of related technologies are studied.
