Research On Calculation Method Of Distribution Network Power Loss Based On Fusion Marketing Data

Electrical energy loss is the loss of power to various power components in power distribution network is often referred to as line loss,namely from the head end of the distribution network(usually substation)to mark for the table,or is lost in the process of watt-hour meter mark sheet to the users of electricity.Distribution network power loss of indirect reflected an electric power enterprise's contribution on the power loss of planning.Distribution network power loss is the core of the enterprise economic benefit,will only loss and line loss.Suggestions gradually increase to improve the enterprise benefit of power supply bureau.So each enterprise to reduce the line loss,as efforts to corporate goals.This paper mainly studies the content:(1)At first,all kinds of theory analyzes the power distribution network loss calculation method and relevant concepts of line loss,at the same time analysis of distribution network power loss research status at home and abroad.Incomplete data based on the low voltage distribution network marketing,as well as the low voltage distribution network in the network topology structure is complex and complicated,detailed introduces the calculation method and model of low voltage distribution network in electric power.Due to the different mains electricity way to also should have different load,different types of such as heavy load,medium load,light load.According to different types of load on the classification and the establishment of the corresponding power loss calculation method.(2)Based on a certain area of yunnan S city distribution network marketing data and area of electricity measurement data,the distribution network line loss,the loss of distribution transformer,such as copper loss and iron loss to comprehensive analysis and computing power loss and power line loss.suggestions.And puts forward some about the model of low voltage of the electric energy loss in distribution network to achieve S city distribution network in a given area of yunnan province were compared and low pressure line loss.suggestions in theoretical calculation of line loss in detail.According to the distribution network power loss theoretical calculation and analysis of line loss.suggestions,analyzed the power loss in distribution network power loss percentage of each element.(3)Finally,BP neural network model is established,the power feed lines the way based on the measured data of the loss of the training set and testing set of prediction and error analysis,at the same time,in the original GRNN generalized neural network model,on the basis of using the particle swarm algorithm of generalized neural network model is improved and optimized,composite learning algorithm of PSO,GRNN model was set up,on the whole distribution network power has carried on the theory of total loss.loss is the actual loss of the error analysis,realize the S area monitoring and analysis on the distribution of energy dissipation,the S regional electricity distribution network loss prediction and loss reduction has played a certain theory instruction function.
