The Study Of Line Loss Analysis And Loss Reduction Measures Of GY District 10kV And Below Distribution Network

Power line loss is the power supply enterprises to measure the level of comprehensive management and operational efficiency of the important content.At present,China's line loss rate compared to the world's developed countries,or in a high state,in different provinces of China Southern Power Grid of the line loss rate is also very different,indicating that the current power line can also reduce the line loss Further study to reduce power loss.With the emphasis on the line loss of the China Southern Power Grid Corporation,a variety of measures to reduce losses also continue to improve,the current power grid in terms of the South,the line rate of loss has advanced into the ranks,which is a positive response to the national energy-saving emission reduction is given the best Action,for the country's economic development to provide a strong power protection,it is to promote economic development and political influence has far-reaching significance.In this paper,some basic theories of line loss of distribution network are studied,and the theoretical calculation method of line loss is also introduced in detail,and the advantages and disadvantages of various theoretical algorithms are analyzed.Based on the analysis of the present situation and existing problems of 10 kV and below distribution network in a certain area,based on the theoretical calculation of line loss of distribution network and the basic methods,the results of theoretical line loss calculation of Gy distribution network in 2015 are analyzed,The influence of load type,connection mode and operation mode,line loss and transformer loss on distribution line loss are analyzed and the problems are analyzed.The problems and weak links are analyzed.And the energy saving measures are also studied.This paper will be an important guide to enhance the economic performance of the distribution network,because this paper can provide guidance for the planning and construction of power grids,and provide the basis for enhancing the economic operation level of the power grid and reducing the power loss and line loss.
