【摘要】：在国家电网“大运行”体系背景下,各地区电网逐步建立起将电网调度管理和监视控制进行一体化运行的管理模式,随之“调控一体”自动化系统在国内各地快速发展。为了提高冀北地区电网调度运行管理水平本文对国内外电网的运行管理模式和调度自动化系统的现状和发展趋势进行了深入地了解,并对冀北地区电网调度运行管理及其调度自动化系统的现状进行了分析研究,构建出一套符合冀北电网500k V变电站运行管理模式,适合冀北电网500k V变电站发展的“调控一体”自动化系统。本文首先对国内外电网的运行管理模式和调度自动化系统的现状和发展趋势进行了介绍,对冀北地区电网调度运行管理及其调度自动化系统的现状进行了分析研究,进而提出了冀北电网500k V变电站“调控一体化”系统建设的实施条件、设计目标、设计原则及功能需求分析。然后从实施条件、系统组成、配置及网络方案等方面对“调控一体”自动化系统实施方案进行详细介绍,分析说明了冀北电网500k V变电站“调控一体”自动化系统的主要技术特点,对500k V变电设备的调控层面进行分析,指出了网、省层面实现500k V变电设备“调控一体化”具有的优缺点。最后,介绍了“调控一体化”自动化系统的实施效果,从提升基础数据质量,提高同业对标水平,常态化断路器远方操作,缩短方式调整和故障处理时间,双重化构建调度数据网,增强二次系统安全防护等方面展现了“调控一体化”自动化系统的应用成果。本文所设计的冀北电网500k V变电站“调控一体化”自动化系统可以集合到现有的调度自动化系统中,不仅能够满足调度中心的应用需求,而且适应“大运行”系统建设方向要求,构建的技术支持系统安全稳定、可靠,显著提高调度人员及其监控运行人员的工作效率。
[Abstract]:Under the background of "large operation" system of State Grid, the management mode of integrated operation of power dispatching management and monitoring control has been gradually established in various regions of power grid, and the automation system of "integration of regulation and control" has been developed rapidly in all parts of the country. In order to improve the management level of power network dispatching in the north of Hebei Province, this paper makes a deep understanding of the current situation and development trend of the domestic and foreign power grid operation management mode and dispatching automation system. The present situation of dispatching operation management and dispatching automation system in north Hebei power network is analyzed and studied, and a set of operation management mode of 500kV substation in north Hebei power network is constructed. It is suitable for the development of 500 kV substation in north Hebei power grid. Firstly, this paper introduces the current situation and development trend of domestic and foreign power grid operation management mode and dispatching automation system, and analyzes and studies the present situation of dispatching operation management and dispatching automation system in north Hebei power network. Furthermore, the implementation conditions, design objectives, design principles and functional requirements of the "regulation and control integration" system construction of 500kV substation in North Hebei Power Grid are put forward. Then, from the aspects of implementation conditions, system composition, configuration and network scheme, the implementation scheme of "regulation and control" automation system is introduced in detail. This paper analyzes and explains the main technical characteristics of the "regulation and control integrated" automation system of 500kV substation in north Hebei power network, analyzes the regulation and control level of 500kV substation equipment, and points out the network. It has the advantages and disadvantages of realizing the 500 kV substation equipment 'regulation and control integration' at the provincial level. Finally, the paper introduces the implementation effect of the "regulation and control integration" automation system, including improving the quality of the basic data, improving the standard level of the same industry, normalizing the remote operation of the circuit breaker, shortening the adjustment of the mode and the time of the fault handling. The dual construction of the dispatching data network and the enhancement of the security protection of the secondary system show the application results of the "regulation and control integration" automation system. The "integrated regulation and control" automation system of 500kV substation in the north Hebei power network can be integrated into the existing dispatching automation system, which can not only meet the application needs of the dispatching center. In addition, according to the direction of "large operation" system construction, the constructed technical support system is safe, stable and reliable, and significantly improves the work efficiency of dispatchers and their supervisory and operating personnel.
