The Study On The Line Loss Of 10kV Line And Its Stage Area Based On Metering Automation

With the rapid development of the social economy,the demand for electricity is constantly improving,which also provides a great help for the development of power enterprises.Power supply lines have become more standardized in upgrading and upgrading,which has resulted in remarkable achievements in the marketing management of power enterprises.But in fact,the electric power enterprise marketing line loss management still exist some need to improve the content of the need to continue to deepen reform of marketing management and electric power enterprises to strengthen line loss management,to enhance the power supply enterprise economic management efficiency.This paper first describes the research significance,purpose and the development status of marketing line loss management.Foshan power supply bureau by comparison and analysis of nanning power supply bureau,the status of the marketing management line loss found at this stage because of weakness of basic data,meter reading is not in the same period,metering automation level is not high reason,nanning power supply bureau of 10 kv line and area line loss is unable to calculate accurately.This paper selects the pilot line and the Taiwan area of the tsing xiu sub-bureau of nanning power supply bureau,and carries out the research and analysis of the line loss through the use of the metering automation system,and finds the shortboard of marketing management line loss.This paper firstly analyzes the classification of line loss and the concept of theoretical calculation,discusses the calculation method of the loss of various components in the power grid system and the calculation method of traditional distribution network.Combined with practical work,in the process of study,using the equivalent resistance method,area loss method,such as calculation method,using the measurement automation system calculation,the "frozen" zero data metering device,lines,line loss.suggestions area of the same period calculated on a daily basis.Through the pilot line,area during the same period of line loss analysis on the experimental data,found by measuring terminal for the whole installation,the electricity metering device freeze function upgrade,the normal operation of power grid,can accurately calculate the lines,line loss.suggestions area of the same period.Through the experimental results at the same time,the paper analyzes the basic data acquisition,the change of the power grid operation mode,system data correlation,double the power switch,the unification of the relationship between the line become household effects on the same line loss calculation.Deficiency in that the present stage,each major system,cannot achieve sharing data cannot be updated in real time the topological relationship between grid operating,the application of distribution network automation system analysis is limited to the assumptions and data validation phase,has not really realize the function of the system data exchange information between applications.Finally the experimental analysis results are used,from basic data collection "whole",to further standardize the double power metering mode set,enhance the level of system information and specification to carry out the line and abnormal area line loss screening,etc.,put forward the electric power enterprise marketing measures to resolve the line loss management level of ascension.The "can calculate,calculate and apply" line loss management first thought,"apply" to next marketing line loss management,provide the basis for the next step to improve the efficiency of line loss management.
