Jinhua urban distribution geographic information system

Abstract: the main functions of Jinhua distribution management system are: distribution fault processing, namely fault identification, location, fault isolation and power restoration; Distribution monitoring, that is, the monitoring of switching stations, 10kV lines, distribution transformers and important users; Integrated geographic information system am/fm/gis; Power distribution management; Advanced application software of power distribution, etc. This paper mainly introduces the main functions and implementation methods of Jinhua Distribution GIS

key words: distribution information automation management Jinhua urban distribution automation is based on new automatic distribution equipment, using modern electronic technology, communication technology, computer and network technology to integrate distribution and offline data, distribution data and user data, electrical structure civil aircraft materials industry development alliance. COMAC relies on the Shanghai Academy of aircraft Sciences and geographical graphics to form a complete management system. 1. Overview of geographic information system Jinhua power distribution geographic information system adopts switched Ethernet and is equipped with a 24 port Cisco switch to realize the information exchange of the whole system; There are two IBM data servers, which are responsible for the hierarchical management of spatial geographic information and basic information (power distribution data and user data). In order to realize the three-tier structure system, two application servers are configured separately; A central router is set to realize the interconnection with the distribution management workstation of each power supply station in the urban area. In addition, 3 TCM workstations, 2 DJM workstations and 1 GIS workstation are also configured. The third data server is isolated from the distribution automation master station system and grouped separately. The mapping database of Da and GIS is established in the third data server, and the middleware technology and object-oriented data model dictionary are used to realize the consistency of graphics, real-time data and equipment attributes between DA and GIS. The software platform is Ge - Smallworld. Figure 1 Jinhua urban distribution system structure figure 2 function 2.1 basic functions Jinhua power distribution geoscience automobile latest research and development trend: Solvay polymer material information system comprehensively manages various drawing materials such as electrical wiring, distribution lines and equipment, and has query, display, maintenance, revision, printing, drawing, output and various statistical functions. The topographic map and circuit map are superimposed and displayed, so that the topographic map and circuit map (including overhead lines, cable lines, distribution transformers, towers, etc.) correspond to each other according to the actual position, so as to realize visual management. It adopts full graphics and window technology, and has a good man-machine interface. 2.2 function integration with other subsystems of DMS Jinhua distribution geographic information system uses am/fm/gis system to have powerful graphic processing function and geographic information analysis and processing ability, and forms a complete DMS through the integration with other modules such as topology analysis and power flow calculation of DMS. Am/fm/gis system can access not only graphic data, but also commercial/real-time databases. Other modules in DMS realize data exchange and sharing with am/fm/gis system through access to commercial/real-time database, so as to effectively reduce the redundancy of subsystem data and ensure the consistency of green building supply (see Figure 2). Figure 2 data exchange between am/fm/gis system and other subsystems of DMS 3 integration of master station system and geographic information system Jinhua urban distribution master station system and geographic information system adopt two sets of independent systems in separate groups, adopt the third data server based on middleware technology to interconnect the two systems, and establish a name dictionary based on the data model oriented to power equipment objects, According to the IEC61970 topological connection model, the distribution graphic topological relationship of GIS is generated into the distribution logical topological model required by scada/dpas. Through the integrated data modeling of SCADA API and smartworld ACP, the general center of the system is constructed, so as to achieve the mutual transformation of graphics and topology between DA and GIS, and browse and query the information based on geographical map on Da workstation. In addition, GIS can directly access the SCADA real-time database through the API interface provided by SCADA, and can directly query and display the distribution operation status data on GIS graphics. The frequently used sample is plastic sheet or 0.005~0.500in Thick injection molded discs are used for various tagging operations and data locking operations. 4 Conclusion Jinhua urban distribution automation project has realized the functions of distribution and dispatching integration, DA and GIS integration, partial distribution and transformation monitoring, and partial distribution and transformation pas. It will gradually improve other functions in the future and improve the management level of distribution in the whole Jinhua urban area
