Electricity Distribution Network Based On Jgraph Component Of Theoretical Line Loss Analysis System

Electric energy lose of electric distribution network means electric energy lose in electric energy deliver process that power is generated from power station or transformer station outgoing line to consumer electric energy watch. The electric energy loss rate is an index of electric energy exhaust in electric power feed process, it reflects level of the electric power system planning,design and management, is an importance economy,technique index for electrician network management business enterprise. Theoretical electric lose computing means adopting certain mathematics computing model, computing calculability energy lose quantity in the electric energy deliver process basis on electrician network structure,components,run-time parameter, burden circumstance, then base on the calculability energy lose quantity to power supply quantity get the theories energy loss rate of one power distribute line. The importance of the theories energy lose rate is that the electric power supply business enterprise draws up the reasonable management energy lose rate index according to the theories energy lose rate, at the same time, the theoretical electric lose computing also is an important basis in electric power distribution network layout and design process to judge whether it is reasonable and scientific. So it has the great significance to the electrician network management business enterprise.To carry on the theories lose computing, must analysis the electric power distribution network topological structure, needing to ask for help to certain algorithm, data structure or tools to descript the net topology. In strict meaning, the power distribution network topological is directed graph, So use the JAVA open source module-Jgraph to visualize the topological structure of distribution network graphically and use the powerful API base on graph theory to construct the power lose computing algorithm will reduce the development cost and difficult of this graph theory based software. This paper try to expand the Java open source graph visualization component—Jgraph to visualize,describe the net topology of power distribution, then carry on the theories power energy lose computing. At the same time, this paper issues the process of the software annals,design using object-oriented analysis design method and software engineer tools-UML, Rational Roses, an expandable and easy maintainable theories energy loss computing software design,development route and technique point.The software to be introduced by this paper is easy to implement and maintain, with clear structure,friendly interface. Use several testing calculate examples in several cultural heritages as testing calculate example, the computing result express that it can satisfy engineering computing needs completely, has application value to electric power business enterprises; The analysis, design model that this text discussed have very much value to develop this kind of software.
