Application of DCS Integrated Control System in Shenhua Shangwan Power Plant

Abstract: The application information of DCS integrated control system in Shenhua Shangwan Power Plant is provided by excellent flowmeter and flowmeter manufacturers. 1. System Overview Shenhua Shangwan Power Plant Phase III 2x150MW units consist of 2x520t/h circulating fluidized bed boilers, extraction-condensing direct air-cooled steam turbines, and air-cooled generators. Set up one with the auxiliary workshop. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application article details of DCS integrated control system in Shenhua Shangwan Power Plant. 1. System Overview Shenhua Shangwan Power Plant Phase III 2x150MW units consist of 2x520t/h circulating fluidized bed boilers, extraction-condensing direct air-cooled steam turbines, and air-cooled generators. A unit control room is set up with the auxiliary workshop, and each auxiliary workshop is set with an operation station, so as to monitor on the local operation station in case of unit commissioning, start-up and control system network failure. Taking DCS as the core of unit monitoring, an integrated control system for main and auxiliary units is constructed to realize the control and monitoring of boilers, steam turbines, generator-transformer units, plant power systems and auxiliary workshops. DCS adopts HOLLIAS-MACSVDCS developed by Hangzhou Hollysys Automation, which includes data acquisition system (DAS), analog control system (MCS), sequential control system (SCS), furnace safety monitoring system (FSSS), electrical monitoring system (ECS) ), public control system (public electrical system, circulating water pump room, compressed air system, fuel oil system, soda sampling and dosing, etc.), auxiliary workshop control system (water network, ash network, coal transportation), etc. 2. The host DCS circulating water pump room, fuel pump room, soda water sampling and dosing, air compressor room and other systems control the public DCS to achieve centralized control; air cooling system, circulating water pump room system, fuel pump room system, air compressor The system is a remote 10 station, and the communication with DCS is realized through optical cable. The host DCS structure and its main hardware configuration are shown in Figure 1 and Table 1. 3. Auxiliary workshop DCS Auxiliary workshop DCS includes the control of condensate polishing system, dosing system, soda sampling system, boiler supply system, slag removal system, ash removal system, bag filter system and coal conveying system. The centralized monitoring operation point, network and operation equipment of the auxiliary workshop of the whole plant are installed in the centralized control room; the demineralization control system network and operation equipment are installed in the electronic equipment room of the make-up water in the boiler and the control points of various public welfare equipment on site, including boiler make-up water. Treatment control equipment interface, waste water treatment control, circulating water treatment control; condensate polishing control system network and control equipment are installed in the condensate polishing control electronic equipment, including condensate polishing control, chemical dosing and sampling control And rubber ball cleaning control; ash and slag removal control system network and control equipment are installed in the electrostatic precipitator electronic equipment room and on-site process equipment control points, including pneumatic ash removal control, furnace bottom slag treatment control, and air compressor room control The fuel control system network and control operation equipment are installed in the coal handling electronic equipment room and various process subsystems on site, including the coal handling control system and the fuel pump room control system. The DCS structure of the auxiliary workshop and its main hardware configuration are shown in Figure 2 and Table 2. 4. Conclusion After the integrated control system of DCS main and auxiliary units is put into use in Shenhua Shangwan Thermal Power Plant Phase III 2X150MW unit, the monitoring platform is unified as a DCS platform, and the control of the whole plant takes the DCS operator station set in the centralized control room of the unit as the monitoring center. The conventional centralized control of machine, furnace and electricity is realized. At the same time, the auxiliary workshop control is included in the DCS monitoring scope, and some auxiliary workshops such as ash removal and sewage treatment have been unattended. The software and hardware of the control system are unified, which avoids the interface between DCS and various hardware devices, improves the reliability of the control system, reduces the types of spare parts and the maintenance workload of the control system, and greatly saves maintenance costs. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
