电站计算机监控系统网络拓扑研究

Study of the network topology of computer surveil and control system in power plant

电站的计算机监控系统普遍采用分层分布式结构,它将分布在机组控制室的每个现地监控单元利用网络连接起来,组成一个计算机网络。该文根据监控系统速度的要求和系统稳定性的要求,对监控系统的网络拓扑结构及软、硬冗余进行分析,给出了软件冗余的设计思想,讨论了如何选择更合理的拓扑结构以便实现对系统的合理高效控制。

Computer Surveil and Control System(CSCS) is a layer-distributed system, with which the CSCS connects all local control units which are placed in the unit control room into a computer network. According to the speed and stability demands of the CSCS , this paper analyzes the topology structure of the network, details the design of the redundant hardware and software, presents the design thoughts of software, and discusses the principle of choosing a more reasonable network topology to achieve the goal of efficient and safe control.
