【摘要】：随着调度自动化系统结构和功能不断完善,调度员对系统依赖程度越来越高,如何快速准确的发现并处理故障,保障系统安全稳定运行已经成为电力人员十分关心的问题。本课题的研究目的是汇总监视主要系统应用运行情况,通过建立故障经验库作出合理的判断和决策,使自动化系统监视摆脱依靠人工值班的工作模式。向电子值班,无人值守迈进。本文针对自动化系统监视的复杂性,分析了当前自动化系统监视的困难,以及人工监视所存在的问题。从减轻人员工作负担目的出发,根据集中化、智能化、高效化原则来进行设计和研究：首先,分析了系统的总体架构、组网设计以及系统的总体模块设计,并讨论各子模块所要实现的功能。应用架构方面考虑到许多功能需要基础支撑,系统采用基于Qt的C／S三层结构,选用VC作为开发工具,用MySQL数据库来管理所有的告警信息。其次,通过FTP检测通讯接口、IEC104规约数据通信接口实现被监视系统的数据采集,通过对外扩展接口实现短信、APP告警推送及将处理日志传到OMS管理系统。同时通过信号分类来区分告警级别,对不同的告警级别发出不同的方式的告警信号,方便值班员判断。另外,建立基于专家系统的故障经验库来智能判断、定位故障。运用故障处理排序算法为值班员提供最优处理方案。最后,对各子模块及算法实现进行了详细的设计分析,通过图表、文字、代码讨论各部分组成和实现。系统界面简单直观,可通过触摸屏操作,方便值班员使用。根据用户需求,对电子值班系统制定了测试用例,描述了测试报告。对比以往值班员处理故障时长,电子值班系统对故障判断、处理更高效。通过本文设计,可以使电子值班系统向更智能化、综合化发展。
[Abstract]:With the continuous improvement of the structure and function of the dispatching automation system, the dispatchers rely more and more on the system. How to quickly and accurately find and deal with the faults and ensure the safe and stable operation of the system has become a very concerned problem for the electric power personnel. The purpose of this paper is to collect and monitor the operation of the main system, to make reasonable judgment and decision by establishing the fault experience database, and to make the automatic system monitoring get rid of the work mode of relying on manual watch. To e-watch, unattended forward. In view of the complexity of automatic system monitoring, this paper analyzes the difficulties of automation system monitoring and the problems existing in manual monitoring. Based on the principles of centralization, intelligentization and high efficiency, the design and research of the system are carried out in order to lighten the workload of the personnel. Firstly, the overall structure of the system, the design of the network and the design of the overall module of the system are analyzed. The functions of each sub-module are discussed. In application architecture, many functions need basic support. The system adopts C / S three-layer structure based on QT, VC as development tool, and MySQL database to manage all alarm information. Secondly, the data acquisition of the monitored system is realized through the data communication interface of IEC104 protocol of FTP detection and communication interface, and the alarm push and push of SMS app and the processing log are transmitted to the OMS management system through the external extension interface. At the same time, the alarm level is distinguished by signal classification, and different alarm signals are issued to different alarm levels, which is convenient for duty officers to judge. In addition, a fault experience database based on expert system is established to intelligently judge and locate faults. The fault sorting algorithm is used to provide the optimal treatment scheme for duty workers. Finally, the design and analysis of each sub-module and algorithm are carried out in detail, and the composition and implementation of each part are discussed through diagrams, words and codes. The system interface is simple and intuitive, and can be operated by touch screen. According to the requirements of users, the test cases and test reports are developed for the e-watch system. It is more efficient to deal with the fault than the former duty operator, and the electronic duty system can deal with the fault more efficiently. Through the design of this paper, we can make the electronic duty system more intelligent and integrated.
