Design And Implementation Of Line Loss Analysis System For Power System Station Area

Line loss management is an important part of power grid operation and maintenance management.Line loss management is usually analyzed and processed according to the unit of station area.The high rate of line loss will bring the problems of power supply efficiency decline and economic damage to power supply enterprises,which will affect the sustainable development of power supply services.Line loss management needs to deal with a large number of power consumption data,so it is an important way to improve the efficiency of line loss management to use information technology to help managers carry out statistics and analysis of relevant data.This article used Java Web technology,based on the B/S network structure,used the Oracle database,to realize the line loss analysis system of the power system station area.In the article,the system design and implementation process are analyzed and studied in detail.Mainly carried out as follows:1.This thesis first introduces the current status of line loss management informationization at home and abroad,analyses the relevant theory of line loss and the general model of line loss management informationization,and according to the choice of system technology,briefly describes Java Web development technology.2.Subsequently,the detailed requirement analysis of the system is carried out,the application environment and overall development objectives of the system are investigated,and the detailed functional requirements,interaction requirements and non-functional requirements of the system are established.The functions of the system are divided into file management,customs management,line loss statistics,work order management and report management.3.According to the requirement analysis of the system,the system is designed from the overall point of view,including functional model,network topology,functional structure,interaction mode and database.On the basis of the system outline design work,aiming at the abnormal data in the power consumption data acquired by the system,the repair algorithm of the abnormal power consumption data of the system is designed and analyzed.The function integration mode and processing process of the algorithm in the system are introduced.4.Finally,each function module of the system is developed and realized.Thetypical function realization logic and core code of the system are analyzed,and some function pages of the system are displayed.The testing process and results of the system are described as follow.The line loss analysis system studied in this thesis can obtain user’s power consumption data based on power information acquisition system and power marketing management system,and provide tool support for line loss analysis in power network operation and maintenance personnel through data repair and statistical operation,so as to improve work efficiency.
