【摘要】：在电力系统中,继电保护信息管理系统是集计算机网络技术、自动控制技术为一体的系统,这种信息管理系统是电力系统适应新时代网络时代发展的必然产物。在供电公司中应用继电保护信息管理系统可是管理更加灵活、适应领域更广、操作更简便、功能更强大。继电保护装置是电力系统中二次部分的重要组成的部分,对系统的安全性、稳定性和运行的经济性起着重大的作用。我国电力系统继电保护信息的管理基本上是靠人工来完成的,随着科技的发展,有些电厂应用计算机软件进行辅助工作。但是在实用性和灵活性上还存在着一些问题,不能进行推广使用。因此,如何提高电力系统中对继电保护信息的管理,满足电力系统安全的运行,对我国电力系统的发展有着非常重大的意义。本文从变电站的实际情况出发,首先对目前国内外继电保护信息管理系统的现状进行分析和研究,指出了当前使用的继电保护信息管理系统存在的缺点:集成度差、子系统独立、缺乏整合、评估不准确、检修困难等。然后,根据永安供电公司继电保护信息管理系统的实际情况,采用MVC框架,JSP技术和SQLServer2005数据库开发出一套适合永安供电公司继电保护信息管理的系统。能够有效的利用自动化的调度系统,对永安供电公司的继电保护信息系统和SCADA系统之间关系的建立。并通过公司现存的局域网络实现数据的传输,实现了开发成本小,回报大的继电保护信息管理系统。对系统各功能模块进行设计,其中包括了:包括图形操作、定值管理、设备台账、定检记录、动作记录、图纸资料、设备缺陷记录和故障分析模块等。对各模块进行设计最终实现各模块的功能。最后,对本文研究的内容进行总结,和下一阶段工作计划的制定。永安供电公司继电保护信息管理的系统能够把继电保护的日常管理和工作内容链接在一起,实现了继电保护信息管理的自动化,易修改、维护和扩展等优点,为供电公司整体管理水平的提高和经济效益的最大化奠定了一定的基础。本文主要完成了基础性的研究工作,并在这个的研究实践中得到了很多宝贵的经验。从解决实际问题的角度出发,并且严谨、认真的严格,对继电保护信息的接入规范、信息的一致性以及信息的预处理上给出了标准化和规范化的设计。本文根据永安供电公司继电保护信息管理系统的实际情况出发,提出了一种切实可行的继电保护信息管理系统,并对管理系统的安全性和稳定性进行了详细的分析,突出了重点,制定了完善的解决方案,利用计算机技术和通信技术等改善了永安供电公司目前继电保护信息管理系统的人工处理模式,实现了自动化,智能化的管理模型,因此本文的研究具有一定的研究意义和市场应用前景。
[Abstract]:In power system, relay protection information management system is a system which integrates computer network technology and automatic control technology. This kind of information management system is the inevitable product of electric power system adapting to the development of the new era of network. The application of relay protection information management system in power supply companies is more flexible, more adaptable, easier to operate and more powerful. The relay protection device is an important part of the secondary part of the power system, which plays an important role in the safety, stability and operation economy of the system. The management of relay protection information in power system of our country is basically accomplished by manpower. With the development of science and technology, some power plants use computer software to assist the work. However, there are still some problems in practicability and flexibility, which can not be popularized. Therefore, how to improve the management of relay protection information in power system and meet the safety of power system operation is of great significance to the development of power system in China. Starting from the actual situation of substation, this paper first analyzes and studies the present situation of relay protection information management system at home and abroad, and points out the shortcomings of the current relay protection information management system: poor integration. Subsystem independence, lack of integration, inaccurate evaluation, maintenance difficulties, etc. Then, according to the actual situation of relaying protection information management system in Yongan Power supply Company, a set of relaying protection information management system suitable for Yongan Power supply Company is developed by using MVC frame JSP technology and SQLServer2005 database. It can effectively use the automatic dispatching system to establish the relationship between the relay protection information system and SCADA system of Yongan Power supply Company. And through the company's existing local area network to achieve the transmission of data, the development of a small cost, large returns of relay protection information management system. The function modules of the system are designed, including: graphic operation, fixed value management, equipment account, check record, action record, drawing information, equipment defect record and fault analysis module. Finally, each module is designed to realize the function of each module. Finally, this paper summarizes the content of the study, and the next stage of the work plan. The relay protection information management system of Yongan Power supply Company can link the daily management and work content of relay protection, and realize the advantages of automation, easy modification, maintenance and expansion of relay protection information management. It lays a certain foundation for the improvement of the whole management level and the maximization of economic benefit of the power supply company. This paper mainly completed the basic research work, and got a lot of valuable experience in this research practice. From the point of view of solving practical problems, this paper presents a standardized and standardized design for the access specification, consistency and preprocessing of relay protection information. According to the actual situation of the relaying protection information management system of Yongan Power supply Company, this paper puts forward a feasible relaying protection information management system, and analyzes the security and stability of the management system in detail. Focusing on the key points, formulating a perfect solution, using computer technology and communication technology to improve the manual processing mode of the relay protection information management system in Yongan Power supply Company, and realizing an automatic and intelligent management model. Therefore, the research of this paper has certain research significance and market application prospect.
