南水北调东线工程泵站自动化系统设计关键技术

Several Key Technological Problems of Automatic System Design of Pumping Station in Eastern Route of South-to-North Water Diversion Project

介绍了泵站自动化系统的组成与结构,指出泵站自动化系统由计算机监控、视频监视及信息管理等子系统组成,分为现地级、站控级和管理级三个层次,按网络安全分区的原则给出了典型的系统结构,明确了各子系统所处的网络安全区。文章指出了泵站自动化系统人机接口设计应遵循完备、灵活、友好等基本原则,并对泵站现地控制单元两种设置方式(单元式和集中式)的优缺点、系统时钟同步及事件顺序记录(SOE)功能的具体实现、自动控制功能的重要性及事故停机流程设计的注意点等具体技术问题进行了探讨,给出了相关建议。文章最后也指出泵站自动化系统未来将向整个工程系统的联合调度控制方向发展。

This paper gives a brief introduction to the form and structure ot the automatic system m pumpmg stanon. The automatic system in pumping station includes three parts： subsystem of computer monitoring, subsystem of video monitoring and subsystem of information management, and can be divided into three levels： local, station and management. Typical system structure is provided based on network security, and each subsystem has been identified to corresponding network area. This paper gives basic principles on the design of man-machine interface, such as completeness, flexibility and friendly. It also discusses several key technological problems, such as advantages and shortcomings of two settings of local control units, implementation of timing synchronization sequence of event and design of emergency stop control flow. Finally, it points out that the future devel- opment direction of automatic system in pumping station is the joint scheduling of the whole project system.
