| With the developing of economic society, as an efficient energy, electric power plays an important role in people’s daily life. More attention has been paid to the reliability, stability and safety. In order to improve the quality of power supply, the state grid would like to develop smart grid. Distribution automation(DA) is the key technology to make the distribution network more efficient, more reliable, more safety and more stable. DA system contributes to improve the quality of power supply, and it can also promote the economic development.Based on the status of Yanbian distribution network and analysis of Yanbian power distribution network is the main problem, the combination of Jilin province power grid planning principles, and combined with the domestic and foreign advanced distribution automation technology, the planning of distribution automation system construction in Yanbian distribution network. The overall planning and design of Yanbian distribution automation system is carried out from the aspects of a network structure, automatic master station system, terminal selection and communication network.. Objective is the distribution network in normal operation, can realize the measuring function and operation optimization function, abnormal or fault, rapid detection of abnormal and fault section, fault isolation, fast recovery the normal power supply of non fault zone. Reasonably adjust the voltage level, improve the power supply quality and power supply reliability, and provide users with more quality service. And the analysis of the capital investment and the expected results of this plan.At last, the paper also explores the self-healing implementation of Yanbian distribution network after the construction of distribution automation system.. Feeder automation in Yanbian area of urban and rural power grids were respectively the theoretical analysis and provide a reasonable planning and a powerful guarantee for the development of distribution network in Yanbian area. |
