Abstract


At present, Most of the power outage time of electric power users in our country are caused by power distribution network not strong enough, half of the transmission loss occurs in distribution network, so the distribution network should be the key of the development of smart grid power. Distribution automation system upgrade and optimization is one of the important contents to develop the smart distribution grid(SDG).Intelligent automation technologys not only make urban and rural distribution network to the intelligence, efficient, reliable and green development direction possibly, guarantee the power supply security and quality in social, improve the power supply reliability,and also produce more and more obvious economic benefits and social benefit, bring new forward driving force for the field.This paper briefly introduces the current situation of distribution automation technology at domestic and overseas.Expounds the meanings and characteristics of smart grid power.Discuss many key technology such as automation, informationization, the interaction of the SDG.In order to puts forward to construction and reform the SDG,firstly should develop the SDG planning,Build strong power rack for the distribution network automation.This paper mainly research the Electricity supply of 10kV power distribution network in Shangchuan island and xiachuan island in taishan city. It forecasts the power of the load in the future, and puts forward the General framework construction of the distribution network automation system. It Discusses the Structure and function of the system,and Creatively proposes the feasible system construction scheme. It provides practical reference and guidance for development of the SDG in the island.This paper research intelligent terminal equipment and its control technology, and in-depth analysis 10kV wind power generation access technology and secondary technology, combined with the engineering practice discussing and analying the application of construction and retrofit in the SDG..This paper fully investigated and analysis the development trends and characteristics of distribution network domestic and overseas,combined with the actual need of construction of the SDG in the island.under the guidance of inside and outside school teacher, repeatedly discussed and demonstrated by grid design and planning experts with the operation of the experienced technical personnel In the writing process,the Power distribution automation technology in engineering practice to obtain the very good application and promotion, fully emboding it is scientific and practical that this application in the construction of County-level power distribution grid.
