摘要
分散控制系统(DCS)通信网络是连接各控制器和操作站的桥梁,生产过程中的大量监测和控制数据均通过实时网络进行传输,DCS系统实时网络性能对DCS系统安全稳定运行具有重要影响。本文对某发电厂1000MW燃煤机组进行了系统的DCS网络性能测试,给出了以太网链路层健康状况,网络吞吐率、帧丢失率指标、广播风暴抑制功能等测试指标的结果。
DCS（Distributed Control System） communication network system is a bridge to connect the controller and operator stations, a large number of real-time data in monitoring and controling process are transmitted by the network. The DCS system real-time network performance has an important influence on the security of the DCS system. In this paper, a power plant 1000 MW coal-fired unit DCS network performance is systematically tested, and the ethernet link layer, network throughput, frame loss rate, broadcast storm suppression function are given.
