Study and Application of Distribution Automatic System in the Yangjiaping Power Supply Bureau

The power distribution automatic system in the Yangjiaping Power Supply Bureau is a set of genuine power distribution information integration control system, consisting of several organic parts including power distribution network realtime monitoring, feeder automation (FA), power distribution geographic information system (GIS), power distribution flow management system, power distribution information WEB release system and so on. From the angle of the analysis of the structure of the power distribution automatic system, this article introduces the functions and features of the power distribution automatic system. The power distribution network real-time monitoring system has realized the remote real-time monitoring, operation and management of power distribution equipment within main urban zone range and especially played an important role in preventing management from maloperation. Feeder automation (FA) has realized complex power distribution and the functions such as fault detection, fault identification, fault automatic location and isolation, and fast recovery of power supply in non- fault area under multi-point different current statuses and complex network structure; has realized the remote modification fixed value function of power distribution terminal (FTU); power distribution geographic information system (GIS) has realized geographic map based "electronic power distribution network" as well as the communication with SCADA system; power distribution flow management system has realized the vitrification and process-enabling of the production and management of power distribution flow as well as the electronic transfer of power distribution drawings; power distribution information WEB system has realized the function of user's access of "digital network" via Intranet/Internet in any place at any time. The implementation of the power distribution automatic system has made the Power Supply Bureau realize the more accurate and effective management of 10 KV power distribution and finally radically improved the technological level of power distribution management and advanced the reliability of power supply and the quality of customer service.
