【摘要】 电力体制改革、社会发展、科技进步对电网运行、建设的方式产生了重要影响。在这种背景下,电网规划的性质和地位发生了重大变化,面临着新形势带来的诸多问题和挑战。 本文结合作者的规划管理工作实际,分析了建立电网规划管理系统的重要意义,对当前电网规划及管理的研究内容、发展趋势、国内外现状和新时期电网规划工作的思路、管理方式、管理过程以及电网规划管理过程中的数据传递流程进行了探讨,总结了当前电网规划及其管理中存在的问题。针对电网规划管理中数据在空间上的分散、存在“信息孤岛”、传递复杂、过程随机而重要的特点,指出了电网规划管理系统软件开发的核心问题:1、采用软件辅助更好的进行多方面交互和随机管理过程的控制管理;2、提供更加小巧和更能体现中间过程、规划人员拥有最大限度的自由度和控制权的计算支持的实现方式。 采用认知系统工程方法对电网规划及其管理的过程进行研究,总结出了电网规划的过程模型的概念,并结合企业实际管理,分析给出了规划业务的数据传递流程。基于IEC 61970 CIM、OPENGIS等国际标准,分析建立了适于电网规划系统的空间电网数据模型。通过详细需求分析,给出系统整体设计目标。为满足电网规划“强适应性”需求,针对当前“滚动修编”管理方式中实施环节的管理,提出了“规划预警”的概念和功能目标。并从为规划管理提供空间数据可视化及分析工具的角度,探讨了GIS在规划管理系统中的应用。 在系统过程模型、数据模型、功能需求分析的基础上,给出了软件系统的设计与实现方案。系统采用“横向分布、纵向分层”的体系结构、以及面向对象的组件化设计思想,充分保证其良好的开放性、可扩充性、可维护性和实用性。 全文共五部分:第一部分简要介绍电网规划的特点、内容、发展趋势、研究现状和管理体系、管理过程;探讨了新形势下面临的问题、机遇和挑战;对本课题的来源、目的、意义及本文的主要工作进行简单说明。第二部分按照认知系统工程的方法研究规划管理的过程模型和数据、数据的传更多还原

【Abstract】 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.更多还原
