The terminal link of the power network is the distribution network,which is directly connected with the user end,which allows users in the electricity process,on the safety of electricity quality requirements are more intuitive to reflect the power throughout the transmission process It is the last link.In addition,its own to eat the existence of a variety of shortcomings will have a corresponding impact,for example,will affect the reliability and stability of the power grid,the quality of electricity.In order to ensure the user's stable electricity,and better electricity,all aspects of the distribution network must be improved,at the same time,its automation must also be done.In accordance with the State Grid Corporation issued the "power distribution automation pilot construction and transformation of technical principles" in the provisions and requirements,which clearly put forward the power distribution automation network construction should be in accordance with the actual environment of different regions,fully consider the reliability of power supply needs,local economic strength,Power distribution network construction status,communication status and load differences and other factors,combined with regional geographical environment for rational planning and design,the implementation of regional distribution equipment and distribution network of good construction and stable operation,to meet the functional requirements and configuration requirements on the basis of The implementation of the hierarchical hierarchical implementation of the distribution network construction plan.Based on the current situation of distribution network at home and abroad,this paper analyzes the present situation of distribution automation technology at home and abroad,and develops the technical principles applicable to the automation planning of county-level power grids.In addition,for the transformation of a grid,the construction of communication systems and feeder automation and other issues,put forward to meet the requirements of the overall technical program.
