Studies On Line Loss Of Distribution Networks And Measures For Reducing Line Loss In Zengcheng

Electric energy loss rate from transmission line(line loss rate)refers to the percentage of loss for power supply when a power grid enterprise processing the power transmission.Safety,reduce loss,customer service is the three major themes in today's Power grid operation enterprises,the line loss rate is an important technical and economic indicators of the Power grid operation enterprises.Line loss rate which is not only an important symbol to measure the technical level,management level,but also is an important means and effective way of economic benefits to improve the economic operation.As 10 kV distribution network line loss is the main part of the total loss,it is great significance to reduce the loss of distribution network for improving the business efficiency and customer satisfaction.However,the grid enterprises on the high pressure of the main grid of the degree of concern than the low-voltage distribution network,especially 10 kV and below the distribution network is much higher,talent,technology and other resources are also more,resulting in distribution network in resources and management There are more problems.Therefore,the city of Electric Power Bureau,targeted to carry out distribution line loss analysis and take measures to reduce the line loss is a top priority.This paper investigates the current situation of cable loss at home and abroad,and fully understand the importance of line loss calculation and analysis method research in China's energy sustainable development strategy and the power industry gradually to the market and other energy competition,especially according to local conditions Line Loss Problem in Zengcheng District Distribution Network.Based on the actual situation of distribution network in Zengcheng district,this paper studies the problem of line loss calculation theory,line loss analysis and loss reduction scheme of distribution network,and puts forward the problem of distribution network based on the present situation and characteristics of distribution network in Zengcheng district.The paper analyzes the causes and problems of the line loss and analyzes the causes and problems of the line loss.Combined with the "four points" management of the line loss,the author puts forward the design of two dimensions from the technical and management to reduce the power loss and save the resources.Measures to improve the economic efficiency of power supply enterprises and market competitiveness,optimize the power grid structure and power grid planning and design and so on.Among them,the technical measures are to reduce the current power line loss in the inevitable loss,management measures to reduce the current power line loss can be avoided in the unreasonable part.There are no obvious measures between the two measures,can be combined with the application,while simultaneously,so that the effect is more significant damage,more prominent benefits.At the same time,in order to verify whether the proposed reduction measures are feasible and feasible,and to further promote the whole city distribution network,this paper to the new power supply network under the jurisdiction of the distribution as a typical pilot,respectively,Damage and management of the reduction measures,the effect is significant,for the next step line management development direction provides a reference.The research results of this paper have strong practicability,and play an effective role in the reduction and efficiency of distribution network.
