The Design And Implementation Of Power Distribution Management Geographic Information System

The power distribution management geographic information system (the i.e. power distribution GIS system) is Jinan Electric power supply company for the realization enterprise management and operation goal, raises the business management level to invest the construction the management information system. The system construction essential target is Enhances to the power distribution production management effective supervising and managing dynamics, completes take the switching equipment management as the foundation GIS graph platform, in coor with progress of production flow management, provides the synthesis information inquiry, the property management, the maintenance of equipment, the movement management for the enterprise and so on the omni-directional application function information management system.This article uses the object-oriented analysis and the design method, has carried on the demand analysis and the system design to the power distribution management geographic information system, the concrete analysis has designed the table of equipment account material management, the graph and data association blueprint management, the geography information along functions and so on cloth and geography analysis, power distribution movement management, power distribution high-level applied analysis, external system connection.This article has analyzed the system development background and the domestic and foreign electric power business management information system development present situation, briefly described the main question which the system needed to solve, the outline described the system overall situation. Completion proposed which to Jinan Electric power company take switching equipment management as foundation GIS graph platform, in coor with progress of production flow management, provided the synthesis information inquiry, the property management, the maintenance of equipment, the movement management for the enterprise and so on the omni-directional application function power distribution management geography information management system management demand has carried on the key elaboration.In view of the system demand characteristic, has given the system overall construction design, the application construction design, the level construction design, the function construction design separately in the system design process and so on the multi-position system design description. In the equipment modelling detailed design process, to the model design principle, the model involved to the correlation application system connection, uses equipment aspects and so on between attribute, equipment level and analysis situs relations, equipment code which the empty equipment modelling way as well as the object-oriented equipment modelling process involved carries on elaborated emphatically; In the table of equipment account data maintenance method, to maintains the distribution network equipment from living map obtaining using the living map the electrical analysis situs relations, as well as maintained the distribution network equipment from line diagram obtaining using the line diagram the electrical analysis situs to relate these two kind of plans to carry on the analysis comparison, has determined take the line diagram management as the electrical power distribution system main manifestation, take geographic informationsystem as application function integrated contact surface data maintenance way; The line diagram plan aspect, elaborated has used the chart Yuan is the fundamental unit, carried on the edition, the maintenance and the revision to the line diagram, as well as the line diagram logical lamination, labelling and the edition revised, the flow management, contents and so on graph and equipment data association; The living map production aspect, to the geography graph platform shaping, the living map inducted derives, the living map revision, as well as the switching equipment geography along aspects and so on cloth has carried on the elaboration.In the system concrete realization, the realization platform which used to the system has carried on the brief introduction, involved the equipment tree description to the table of equipment account management realization in, the data view description, the form description realization process as well as the table of equipment account data inquiry statistics concrete realization process has carried on the elaboration; In the line diagram concrete realization, to a chart Yuan editor, the line diagram editor, the chart Yuan with the data connection, the line diagram browsing inquiry as well as has carried on the elaboration take the line diagram as the foundation data statistical analysis concrete realization process; In the living map concrete realization, to the living map application environment build, the geography data reorganization, the analysis, inducted, the production has carried on the description, to the living map editor concrete realization, the equipment information geography along living map applications and so on the cloth, living map browsing inquiry, load density analysis and gps localization has carried on the detailed elaboration.This article finally has carried on the summary to all work, completed the situation to the system overall to carry on the objective appraisal, had pointed out this project embarked from the power supply enterprise power distribution production management reality, the union power distribution production management characteristic, had achieved the graph and the equipment data unified the power distribution geography information management system construction goal, obtained the widespread application in Jinan Electric power company, and has obtained in 2006 the Shandong Province computer application outstanding achievement third prize, the Shandong electric power science and technology third prize. At the same time, had pointed out the system next step perfect diligently direction, and to the next step flow intercommunication, data sharing, realized the power distribution production entire process management, the construction power supply enterprise produces the integration to manage the platform and so on the high-level application direction to carry on the forecast.
