| With the rapid growth of national economy and the improvement of life quality during the 11th five years, the requirement for the reliability and power quality is increasing. The blackout that is caused by short-term power failure and the influence for power quality caused by voltage fluctuation will bring huge economic losses, so the power enterprise ask for higher automation requirement at the construction and renovation of power system.DA system is an integrated system that controls and monitors a distance place through secondary equipment distribution network. It has fully reflected the application of the modern computer technology and communication technology in the power systems construction and renovation, and it is the emerging field of power technology research. Industrially developed European countries are actively promoting the development of distribution automation and many research institutes and universities also have stated a lot of work in the related fields in our country. Correct and reasonable distribution automation of distribution network can increase PC quality and the reliability of distribution network, improve the automation of the grid, reduce network losses, improve management efficiency and bring considerable benefits for the user and power enterprise.The paper was on the basis of the research of the application distribution automation systems status and problems in large city at home and abroad, combined the status of distribution network in FengHua, studied the distribution automation application and implementation process deeply through the principle of distribution automation, power distribution master station construction, power distribution terminal building, information system integration plan and network switch transformation, and brought up the detailed plan of the reconstruction of distribution automation system year by year. Finally, the development of distribution automation system of Fenghua was prospected. |
