Research, Planning And Management System Based On Gis Grid

The organizational reform of the electric power, the development of the society and the advance in technology have nowadays all deeply affected the way of movement and construction of the electrical network. So under this situation tremendous changes have taken place to the nature and status of the electrical network's planning, making it faced with many problems and challenges coming up together with the new situation.Linking to author's experience in supervisory and engineering, this article analyzes the importance of the establishment of the plan and management system for an electrical network, discusses the research content, the development tendency and domestic and foreign present situation of the current electrical network's plan and management, looks into the mentality and managing manner of the new time electric network planning and its management process as well as the process of data transmission flow during the engineering and arrangement of an network. And also in the article the author summarizes the problems existing in the current electrical network planning and arrangement. In view of the characteristics that the data transmission is in the spatial disperser, often causing the existence of the "Information Isolated Island" and that the transmission is complex while the process stochastic but important, the author points out the core questions in the software development for the electric network engineering and arrangement system: firstly, software should be used to assist better carries on the control and arrangement in the process of various, alternately and stochastic arrangement; secondly, more approaching ways should be provided on computation support, which are more exquisite and able to manifest the pilot process and allow the maximum of personal freedom and controlling.Harnessing cognition-system engineering method the author conducts the research to the plan and management process of electric network and summarizes the process model concept of electric network engineering. Andalso, referring to the actual management of enterprise, the author gives analysis to the process of data transmission flow in plan service. Based on the international standards such as IEC 61,970 CIM and OPENGIS, a data model for spatial electric network which is suitable for the electric network plan is analyzed and established, and through a detailed demand analysis the overall goal of design for the system is generated. To satisfy the demand of " strong compatibility" of the plan of electric network, the concept of " plan forewarns " and its function goal is proposed, aiming at the current arrangement of implement section in the arrangement model so called "rolling-repair arrangement" . And from the angle of making spatial date visible and providing analyzing tools, the application of GIS in the plan and management system is discussed.The design and realization of software system is given based on the analysis of system process model, the data model and the function demand. The system utilized the structure of " traverse and longitudinal lamination " as well as the object-oriented module design thought, fully guaranteeing its good openness, expansibility, maintainability and usability.Five sections are included in this article. The first part briefly introduces the following features of electrical network planning: the characteristics, contents and development tendency, the present situation of research and its managing system and process. And in this part problem, opportunities and challenges under the new situation are discussed, and simple explanation is given to the origin, the goal, and the significance of the topic as well as to the main work of this article. In the second part, following the idea of the cognition-system engineering method, the author makes a study of the process model of plan management and the data as well as the data transfer mode, analyzes the function demand of the plan arrangement, and sets the goal of the system design. The third part introduces the thought, structure and realization of the system, discussing the realization of the " plan forewarns " function and the application of GIS. The forth part gives the way of realizing the system,including developing the platform, the development kit and the method for realizing them. The construction, function, install debugs and maintaining process of the software are also briefly introduced. The conclusion of the topic and a forecast of next step of the research work are produced in the fifth part.
