Research On Line Loss Analysis And Loss Reduction Strategy Of Distribution Network

Saving resources,green development is a long-term policy of social development of our country,with the rapid development of economy,the popularity of electrification,people's electricity load increasing,the distribution network gradually expand the scale,the structure is more complicated,the power loss is also increasing year by year,how to effectively reduce energy loss of to realize the economic operation of the distribution network is of far-reaching significance.At present,the average loss rate of the network line in China is about 6%,which is higher than that of the developed countries,and the energy saving space is larger.As an important economic indicator of the enterprise assessment,the line loss of distribution network directly affects the economic benefits of electric power enterprises,and it can also reflect the operation level of electric power enterprises.This paper mainly takes the line loss of distribution network as the main line of research,and has done three aspects of work.1.In view of the large number of distribution networks in China,the complex factors of line loss,the high comprehensive line loss and the difficulty of reducing the loss,this paper presents a method of grey correlation,which evaluates the factors that affect the line loss of the distribution network,and does the weight analysis.The purpose is to find the main factors that affect the line loss.Reduce the loss of work to provide reference,improve the efficiency of daily work.2.The traditional method of line loss is not accurate because of the complex structure of the distribution network,the incomplete parameters,the low data quality of the GIS platform and so on.In this paper,a BP neural network loss calculation model of distribution network is established to improve the accuracy of line loss calculation results.The model of 10 kV distribution line in Gannan state power grid is modeled.The results show that the model is simple,powerful,fast and accurate in distribution network line loss calculation.3.Based on the loss reduction strategy of distribution network,the loss reduction strategy is studied based on case study.Based on the actual situation,existing problems and line loss control measures of distribution network line loss in Gannan area,this paper puts forward the idea,management measures and technical measures to reduce the loss of distribution network line loss.Through the research of distribution network line loss,the theoretical line loss calculation method is enriched,and the accuracy of line loss calculation is improved.At the same time,the power loss strategy is used to optimize the distribution network structure,reduce the loss of electricity,reduce the cost of the enterprise,improve the efficiency of the power grid operation,solve the problem of the electric power enterprise,carry out the line loss business,and have a certain guiding role for the healthy and rapid development of the enterprise.
