As the terminal of an electric network, the distribution network is directly connected with the users. It is charactered with wide spread line, low voltage level, many devices on the line.Lineloss of distribution takes up considerable ratio in the general network. Picking out the potential is very important to the efficiency of supply enterprises.The paper discusses the origin of line loss and its analyzing method, compares the measurement for reducing line loss in practical distribution network and factors influencing the variation of line loss, and investigates the theory using for analyzing line loss. In this paper, combing the character of TaiAn Eletric Power Corporation, based on Sql server 2000 database we designed a system with the Java language and JSP technology which aims at the calculation analysis and reducing lineloss of the distribution netpower.It had many functions, for example added data and edited data and found data and so on.
