【摘要】：随着变电站监控技术不断发展,特别是自动化水平的不断提高。工业生产、商业、生活对输配电需求越来越来,而变电站作为输配电的重要环节对自动化的要求越来高。提高监控系统的监控水平,能够促使变电站形成一种集数字化、网络化、智能化和自动化于一身的管理体系。因此,优化变电站的监控系统,为广大用户提供一个实际、安全、先进、友好的系统,不仅可以保证变电站的安全运行,达到变电站监控系统的高标准、高要求,而且能够解决变电站的安全维护问题,可谓是一箭双雕。所以变电站监控系统改造实施的研究意义重大。本文首先介绍了监控系统发展过程中经历的三个阶段的概况,在变电站中的具体应用范围和110kV东侨变电站监控系统改造的范围。其次对变电站自动化系统的进行了技术分析,阐述了自动化系统集中式结构、分散式结构、分层分布式结构和集中分散结合式结构的优缺点；介绍了变电站监控系统的通信模式,明确通信目的、通信传输方式、通信接口。通过分析各种系统结构和通信方式的特点,为监控系统改造的配置提供选择方向。同时文章还对变电站的其他功能加以相近的描述,比如变电站的数据监测、变电站的安全监察、正常开关和运行等等,这不仅对变电站的监控系统提出了更高的技术性要求,同时也奠定了改造监控系统的理论基础。接着,本文针对110kV东侨变电站监控系统改造前的特点提出设计方案和设配置,包括系统结构选择、系统通信方式选择、硬件设备的配置和一些通信方案的选择。最后提出一些监控改造过程中的施工技术和拟定可能发生的危险点,并进行预控。110kV东侨变电站的监控系统的升级改造,是加强电网安全、稳定生产的重要保证,是一项势在必行的工程项目。
[Abstract]:With the continuous development of substation monitoring technology, especially the continuous improvement of automation level, industrial production, commerce, and daily life demand more and more for transmission and distribution. Substation, as an important link of transmission and distribution, requires more and more automation. Improving the monitoring level of monitoring system can promote the substation to form a management system that integrates digitization, networking, intelligence and automation. Optimizing the substation monitoring system to provide a practical, safe, advanced and friendly system for the majority of users can not only ensure the safe operation of the substation, but also meet the high standards and requirements of the substation monitoring system. And it can solve the problem of substation safety maintenance, it can be described as "kill two birds with one stone". Therefore, it is of great significance to study the transformation and implementation of substation monitoring system. Firstly, this paper introduces the general situation of three stages in the development of monitoring system. The scope of application in substation and the scope of transformation of 110kV Dongqiao substation monitoring system. Secondly, the technical analysis of substation automation system is carried out, and the centralized and decentralized structure of automation system is expounded. This paper introduces the communication mode of substation monitoring system, defines the communication purpose, communication transmission mode, communication interface, and analyzes the characteristics of various system structures and communication modes. At the same time, the paper also gives similar descriptions of other functions of the substation, such as substation data monitoring, substation safety monitoring, normal switching and operation, and so on. This not only puts forward higher technical requirements for substation monitoring system, but also lays the theoretical foundation for the transformation of monitoring system. Then, this paper proposes a design scheme and configuration for the characteristics of 110kV Dongqiao substation monitoring system before transformation. Including system structure selection, system communication mode selection, hardware equipment configuration and some communication schemes selection. Finally, some construction techniques in the process of monitoring and transformation are proposed and possible hazard points are drawn up. It is an important guarantee to strengthen the safety and stable production of power network to upgrade and transform the supervisory control system of Dongqiao substation, which is an imperative project.
