【摘要】 论文主要研究工作是新型变电站自动化监控系统的结构与功能实现,通过计算机、通信和网络等技术的充分利用,提出了一种新型监控系统结构。论文首先分析了常用变电站综合自动化系统的结构、特点以及不足,并在此基础上,提出了一种基于4层结构模型的变电站综合自动化系统。它采用的是一种分层的功能模块化设计思想,整个系统按照多层体系结构进行分布式设计,利用统一的实时数据库平台为各种应用程序平台提供数据信息服务,硬软件可做到模块化、通用化,可根据不同类型变电站的要求实现不同的系统配置。整个系统的可靠性较高,可维护性和开放性良好。针对关系型数据库系统在变电站自动化系统实时应用中存在的缺陷,根据文中所提出的变电站自动化系统的结构与特点,分析了基于此系统的实时数据库系统的构成,并利用面向对象技术提出了变电站自动化系统实时数据库的数据模型、接口实现方法以及内部实现过程,对其体系结构、分布式机制、系统特色等方面进行了探讨。论文还给出了系统各软件模块的设计思路与流程,通过运用模块化程序设计方法将后台监控系统按层分成诸多模块,在每个模块的具体设计上立足于面向对象程序设计思想,然后选择相应的开发工具进行有效开发。最后,对本学位论文的全部工作进行了总结,提出了目前设计中有待进一步完善和改进的问题。更多还原

【Abstract】 A new integrated substation automation system based on the development and application of computer,communication and net-work is put forward, The main work focuses on the research and realization of this new system.。The structure and features of integrated substation automation system in common use are analyzed. Based on the analysis of the insufficiency of usual integrated substation automation system, a new integrated substation automation system on the basis of the model with four-layer architecture is put forward, and the layered function modularization design idea is applied to developing this system. Furthermore, with the modularization and universal of software and hardware, the configuration of system will be diverse according to the connection ways of primary equipment in different type of substation. The reliability, maintainability and opening of new system are improved. The structure and principle of this system are expounded in the paper.With an aim at the limitation of the relative database system existed in the real-time application of substation automation system, the paper analyses the composition of the real-time database (RTDB) of substation automation system according to the feature of substation Automation. A method of realizing data model and interface using Object-Oriented technology is given. The system structure, distribution mechanism and some system’s features is introduced also.The design and realization of different software module is introduced also, with the using of Object-Oriented technology, the software is easy to be updated.Last, a summary and further work of this system are given.更多还原
