Optimization Research And Application Of Distribution Automation With Small Hydropower Grid-connected Lines

In recent years,the technology of distribution automation has gradually spread in the county power supply unit,but there are also many practical problems,on the one hand,the power supply unit of space truss structure is different,on the other hand,in recent years due to a large number of distributed power supply,such as small hydropower into distribution network will be a larger influence on the practical application of distribution automation,need to constantly improve the implementation plan.For optimization of distribution automation with small hydropower grid-connected lines,this article based on the characteristics of small hydropower station in DianbaiCountry,this paper puts forward the method of installing intelligent switch in the grid site of small hydropower station,and puts in the corresponding protection function to optimize the automation of distribution network of this type of line.First,this paper expounds the characteristics,the development of distribution automation at home and abroad present situation and the importance and necessity of the implementation of distribution automation,the description of its basic concept and main features,this paper introduces the system main function,different technology mode of feeder automation line treatment failure,line maintenance and operation mode adjustment,communication function and the effect of automation terminal.Then,detailed research and analysis the distribution automation implementation and application of the pilot program of Dianbai,proposed the overall planning and implementation ideas in line with the region,also proposed the priority of objects.At the same time,a specific transformation plan was made for 10 kV lines with typical different power grid structures.Finally,the paper analyzes the impact of small hydropower grid-connected on distribution network operation and distribution automation application,proposed different optimization improvement strategies for the small hydropower grid-connected lines,and aiming at the typical small hydropower grid line 10 kV Luokeng line made specific research and analysis,through the analysis of the implementation and application effect of modified,the optimization is obtained after application of economic and social benefits,has a strong practical significance.
