【摘要】:继电保护是在被保护的元器件发生故障的情况下,能快速、自动将故障从电力系统都切除,确保故障元件不会继续受到损害,同时无故障元件正常工作,避免事故扩大化。因而继电保护对电网的安全运行特别重要。宜宾局继电保护整定计算及管理系统的基本指导思想是:实现整定计算及定制管理流程的智能化,实现整定计算及定制管理的自动化。系统主要解决的技术问题是整定计算,其内容包含智能图形化建模算法、智能图形操作算法和装置保护整定计算和以上三种算法的优化;系统数据通过网络数据库管理,通过软件系统各种数据的交换和数据共享。采用全面的图形化操作管理,通过图像化技术来表达电网结构,用户在进行整定计算和管理时,可通过图形化界面操作完成,同样系统数据的显示也使采用图形化的方式,任务参数和计算结果都可以从图上观测到。在系统开发过程中采用面向对象技术和组件化的设计思路将系统划分为多个模块,适应系统管理上地域差别和系统的扩展,确保软件具备可扩展性和可移植性。宜宾局继电保护整定计算及管理系统采用C/S接口,系统采用成熟的C++开发语言实现,采用全面的图形化操作管理,通过图像化技术来表达电网结构,用户在进行整定计算和管理时,可通过图形化界面操作完成,同样系统数据的显示也使采用采用二维可视化技术,实现对设备和元器件的技术参数和整定计算结果叠加在可视乎图形上显示。系统实现了220kV主变和110kV线路及以下电网继电保护定值整定全过程的智能化,关键问题的自动化化,以及用户操作过程的全方位图形化,并提供了全面的故障计算功能,具有丰富的标准化结果输出功能,全面而灵活地考虑了整定的各种规则,以及各种不同装置的差别,还对整定计算中的一些难点问题提出了一些新的解决方法。其在继电保护运行管理中的应用,必将大大提高整定计算的工作效率。
[Abstract]:Relay protection can quickly and automatically remove the fault from the power system and ensure that the fault element will not continue to be damaged, and at the same time, the fault element will work normally and avoid the expansion of the accident. Therefore, relay protection is particularly important to the safe operation of power grid. The basic guiding idea of the relay protection setting calculation and management system of Yibin Bureau is to realize the intelligentization of setting calculation and customization management flow and to realize the automation of setting calculation and custom management. The main technical problem of the system is setting calculation, which includes intelligent graphical modeling algorithm, intelligent graphic operation algorithm, device protection setting calculation and optimization of the above three algorithms, and the system data is managed by network database. Through the software system of various data exchange and data sharing. The overall graphical operation management is adopted, and the power network structure is expressed by the graphic technology. The user can operate through the graphical interface in setting calculation and management, and the display of the system data also makes the system adopt the graphical way. Both the task parameters and the calculated results can be observed from the diagram. In the process of system development, the system is divided into several modules by using object-oriented technology and component-based design idea, which adapts to the regional differences in system management and the expansion of the system, and ensures the extensibility and portability of the software. The relay protection setting calculation and management system of Yibin Bureau adopts the C / S interface, the system is realized by the mature C development language, the overall graphical operation management is adopted, and the power network structure is expressed through the image technology. In setting calculation and management, the user can operate through graphical interface, and the display of system data also enables the use of two-dimensional visualization technology. The technical parameters of equipment and components and the results of setting calculation can be displayed depending on the graph. The system realizes the intellectualization of the whole process of setting the value of the 220kV main transformer and the relay protection of the 110kV line and below the power network, the automation of the key problems, and the omni-directional graphics of the user operation process, and provides the comprehensive fault calculation function. It has abundant function of standardized result output, considers all kinds of setting rules and the differences of different devices, and puts forward some new solutions to some difficult problems in setting calculation. Its application in relay protection operation management will greatly improve the working efficiency of setting calculation.
