one. prospect
The urban distribution network directly faces many users and is a bridge between power supply companies and power engineering customers. In addition, it has the characteristics of complicated wiring, large amount of data, and frequent changes. With the development of social economy and the improvement of the quality of life of ordinary people, higher and higher requirements are put forward for the reliability of the power supply system, power quality analysis and service level, and higher requirements are clearly put forward for the distribution network management information system . Shantou Hongjing High-tech Co., Ltd. clearly puts forward the solution of distribution network GIS system for such requirements, closely links distribution network operation management methods, equipment maintenance and safety work, and pushes the application of natural geographic information systems to a new level. new heights.
two. The design concept
distribution network management method involves various information, including natural geographic information, machine equipment information, operation information, customer information, etc., refine the information of the distribution network and express it in the form of a graph, so as to generate distribution network information. The coating space of the network can carry out various information levels and reflect them on different coatings, which is conducive to the level management and level maintenance of the distribution network information, and the dynamic composition of the coating.
three. Technical features
Starting from the excellent natural geographic information system technology, it integrates communication network, database, natural geographic information and other technologies to form a distribution network GIS system with the characteristics of modern management methods.
The completion of the system uses large and medium-sized databases and natural geographic information service platforms. All distribution network information is stored in large and medium-sized database files. The database required for geographic information only stores some basic characteristic information of distribution network equipment and customers. Connect large and medium-sized databases and table data based on key features. The browsing and control of the data has applied the OLE automation technology network server port technology.
With the development trend of the Internet and Internet technology, the natural geographic information system operating in the natural environment of the Internet or Intranet can complete the distributed system of natural geographic information, the release of indoor spatial information, address query and topographic maps in the natural environment of the Internet Displaying information is a brand-new network hotspot industry in the current GIS industry. For the application of the distribution network, the system takes into account the ability to expand its work in the future, and reserves the development and design technology to upgrade to the company-level distribution network GIS application system of shared resources when necessary.
Four. System effect
The system's operation panel is visualized and has powerful graphics functions. For the maintenance of graphics, data maintenance is very convenient, and the information of each subsystem is relevant and predictable. While maintaining graphics, users can perform operations such as adding, deleting, and modifying system performance data, and can also input performance data on existing graphics.
The system has fully open configuration, map operation and map tool functions. The fully open system configuration content includes: multi-directional route model, supports user-defined equipment types, supports user-defined ledger data characteristics, map operation has stepless scaling, and graphic display "eye-catching" effect. On the distribution network diagram, various characteristic data of equipment and safety can be accessed, queried, and statistically analyzed, and it can be popped up to display the full junction curve diagram of the information substation equipment. The operation status of various equipment can be displayed visually on the map.
five. Scope of application
The system can be successfully applied to the distribution network management of various power companies. After renovation, it can also be applied to the management of urban and rural planning roads and underground pipe networks.
