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

At present,the degree of intelligence of the distribution system in most areas is not high,and the study of practical theoretical line loss calculation methods in conjunction with the local actual situation can still greatly enhance the efficiency and save costs for the local power sector,which is the significance of this thesis work.Based on the characteristics of various traditional line loss analysis strategies,this thesis summarizes and summarizes the more commonly used theoretical line loss analysis strategies.Aiming at the shortcomings of traditional theoretical calculations,an improved method for calculating the line loss of the distribution network is proposed to guide the loss reduction operation of the distribution network.In view of the complexity of distribution network lines,a BP neural network line loss calculation model is constructed,and the correlation between power and line loss is found by inputting active power and reactive power,and outputting the line loss rate of the target line.Use Matlab software tools to realize the application of neural network model and calculate the line loss of the studied line.Finally,the line loss optimization method is used to perform the corresponding line loss compensation,so as to achieve the final loss reduction target.Compared with the traditional method,the optimized scheme has higher efficiency and lower loss,which has achieved the expected design goal.This paper combines the study of the common local line loss situation in Mianyang and integrates the current situation of local power grid operation to give an effective strategy and process for loss reduction in distribution networks,mainly oriented to the range 10 k V distribution lines,giving a loss reduction strategy,analyzing in detail important parameters such as node selection,compensation selection and capacity selection in terms of theory,while developing an optimal strategy in combination with the actual distribution and usage.On this basis,the social and economic benefits that can be brought by the integrated use of line loss control and reactive power compensation are briefly discussed,providing a feasible case for the energy saving scheme in the power sector,with the dual significance of theoretical research and practical application.
