Integration of DCS control system in shenhua bay power plant application

Abstract: the integration of DCS control system in shenhua bay power plant the application of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. One, system overview shenhua bay power plant on three phase 2 by 2 x520t x150mw unit/h circulating fluidized bed boiler, the smoke condensation type of direct air cooling steam turbine, air cooling generators, using machine, furnace, electric centralized control mode, and auxiliary workshop 2 units and set up an auxiliary workshop. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the integration of DCS control system in shenhua bay power plant the application of article details. One, system overview shenhua bay power plant on three phase 2 by 2 x520t x150mw unit/h circulating fluidized bed boiler, the smoke condensation type of direct air cooling steam turbine, air cooling generators, the machine, furnace, electric centralized control mode, and auxiliary workshop 2 units and auxiliary workshop to set up a unit control room, the auxiliary workshop set operating station, so that the plant commissioning, start-up and control system under the condition of network fault on the on-site operation site monitoring. The DCS is the core of the monitoring unit, construction of main, auxiliary engine integrated control system, realize boiler, turbine and generator transformer group, the auxiliary power system and the control and monitoring of auxiliary workshop. DCS using HOLLIAS - hangzhou hollysys automation development MACSVDCS, which include data acquisition system ( DAS） , analog control system ( MCS) And sequence control system ( SCS) , furnace safety monitoring system ( FSSS） , electrical monitoring and control system ( ECS) , common control system ( Public electrical system, circulating water pump house, compressed air system, fuel system, soda, sampling and dosing control) , auxiliary workshop control system ( Water, ash, coal) And so on. Second, the host DCS circulating water pump, fuel pump, soda, sampling and dosing, air compressor machine room control system, such as one common DCS, realize centralized control; Air cooling system, circulating water pump house system, fuel pump, air compressor system for remote station 10, by optical fiber cable communication with DCS. The host structure of DCS and its main hardware configuration as shown in figure 1, table 1. Three, auxiliary workshop DCS auxiliary workshop DCS including, dosing system, soda in condensate polishing treatment system sampling system, boiler replenishment system, slag system, ash removal system, cloth bag dust catcher system, the control of coal conveying system. Plant auxiliary workshop centralized monitoring point operation, network and operating devices are installed in the ecr. Desalination control system network, operating equipment installed in a pan, supply water, such as electronic equipment and field between various good equipment control points, the boiler make-up water treatment control system including interface, wastewater treatment, water treatment control; Condensate polishing processing control system network and the control equipment installed in the condensate polishing processing control electronic equipment, which include the condensate fine treatment control, chemical dosing, and sampling control as well as the rubber ball cleaning control; Ash slag and control equipment installed in the electric control system network devices and field between each process equipment control points, including the pneumatic ash control, furnace bottom slag processing control, air compressor machine room and bag dust control, etc. ; Fuel control system network and control the operating equipment installed in the coal electronic equipment and site between each process subsystem, which include coal conveying control system and fuel pump control system. Auxiliary workshop DCS structure and its main hardware configuration is shown in figure 2, table 2. Four, conclusion DCS main auxiliary integration control system in shenhua bay, after three periods of thermal power plant unit 2 x150mw putting-in-service proactively monitoring platform for DCS platform, the coordination control to set the unit in centralized control room of the DCS operator station to the monitoring center, implements the conventional machine, furnace, electric centralized control. At the same time, the auxiliary workshop control should be brought into the scope of DCS monitoring, ash, sewage treatment and other parts of auxiliary workshop have been realizing unattended. Unified control system hardware and software, to avoid the DCS interface with a variety of hardware equipment, improve the reliability of the control system, reducing the workload of maintenance spare parts and control system, greatly save the maintenance cost. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , mass flow meter, u shape coriolis mass flow meter, and insertion ultrasonic flow meter are widely used.

For details on mass flow meter, see Beijing Sincerity Automatic Equipment Co., Ltd at Sincerity Flow Meter.

In a nutshell, is actually an ultimate solution for endress hauser coriolis mass flow meter and underestimating its value cost you higher than anything else. So grab it before you miss the boat.

So, what's a manufacturer to do? Familiarize ourselves with producing mass flow meter in various technologies.
