Research On The Design Of The Long-distant Monitor And Control System Of The 600MW Generating Unit Water Treatment Plant

The PLC is applied to wide–ranging industries, such as electric power ,chemical industry, metallurgy, etc. The PLC technique has been developed quickly in recent years. Among them the Siemens S7 series—–the technique of integrating the live broadcasting total lines—–with flexible arranging system, is applicable to the situation with decentralizing course control .The dissertation is mainly about the application of the automation means in the water treatment plant, such as the S7 PLC, PC the upper part SCADA software ,industrial internet, etc. And how to monitor and control the produce and management of the whole plant in order to improve the automatic level of the whole plant by using this means.The main points are as following:The introduction of the industrial course control network of the Tuoketuo 4*600MW generating unit water treatment plant and the design optimization.The application of communication techniques, The characteristics of the industrial internet technique and PROFIBUS and their concrete application to the control of the Tuoketuo power plant and water treatment plant ,The introduction and application of Simens S7300 PLC.The application of Process Device Manager software and corresponding analogue input unit, the attachment of HART Agreement transmater to the PLC system.The communication with the MOELLER PLC(the PLC which is in accordance with the PRUFIBUS DP Agreement) in the network communication interface.The communication with the device (in accordance with MODBUS Agreement RS485 interface) in the network communication interface.The concrete application of STEP7 software in the industrial controlling course.Xu Xiangyang(power plant Thermal power engineering)Directed by prof.
