摘　　要：主要介绍长江三峡大坝的泄洪闸门控制工程,工程包括47个泄洪闸门,位于大坝中部,分为3组。泄洪闸门分别由14个S7-400 PLC本地站(Profibus-DP主站)和45个ET-200M远程站(Profibus-DP从站)进行控制。它们被配置成二级网络,高层是冗余光纤控制网络(100兆以太网),底层为现场总线DP网络。该项目是世界上最大的水利工程项目。This article describes the spillway gates control project of Yangtze River Three Gorges dam. There are forty-seven spillway gates in the middle of the dam of Three Gorges. They can be divided in three groups. There are fourteen local stations of S7-400 PLC (Profibus-DP masters) and forty-five ET-200M remote stations (Profibus-DP slave). They are arranged in two levels network. The high level net is Redundant Fiber OpticControl Network (100M Ethernet network)and lower level is Profibus-DP network. This is the biggest hydraulic engineering project in the world.
