Invensys process systems has been selected to provide advanced Scada systems for the Yanjiang oil pipeline in China. The new automation project is based on the I/A Series Scada master station from Foxboro and includes SCD5200 RTUs from Foxboro and InTouch human machine interface software from Wonderware. Sinopec Pipeline Storage and Transportation Co. (Sinopec PSTC) will use the Scada solution for remote data monitoring and control to support a range of dynamic applications. These include alarm processing, leak detection, hydraulic analysis, pump station monitoring, throughput analysis and related applications along the 1300km pipeline. The new system will collect data from, and supervise control of, third-party PLCs at each of the pipeline’s 14 pumping stations. Wonderware’s InTouch HMI software will provide pipeline visualisation at these pumping stations. Along the entire length of the pipeline, block valves will be remotely monitored and controlled using SCD5200 RTUs, real-time Scada processors designed to support complex remote applications. The communications protocol for the system will be DNP3.0 over Ethernet and optical fibre as the backbone, backed up by PSTN.
