Coal-fired power plant thermal control automation level is through the control mode, control room layout, configuration and function of the thermal control automation system, the running organization and the main auxiliary equipment control aspects of the comprehensive embodiment. The level of thermal control automation system design, the operation personnel. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a thermal control automation system monitory point set case article details. Coal-fired power plant thermal control automation level is through the control mode, control room layout, configuration and function of the thermal control automation system, the running organization and the main auxiliary equipment control aspects of the comprehensive embodiment. Level of thermal control automation system design, to optimize the configuration of the operators and reduce labor intensity has great influence. Thermal control design of the automation system should be based on the actual situation of power plant, the reasonable configuration and decentralizing control system, personnel distribution, equipment under control. A, 1 phase of the set point to point huaneng huaiyin power plant phase 1 to 2 units of 220 mw coal-fired unit, completed and put into operation in 1993. After the modification of control system for many times, automation system is configured to: using power plant computer integrated manufacturing system ( CMIS） Implementation of real-time data collection and management. 2 units respectively set the unit control room, unit adopts the distributed control system ( DCS） Furnace, machine, electric centralized control. Auxiliary workshop for coal, water, ash and 3 monitoring points, ash removal system USES independent programmable logic controller ( PLC） Network control, coal and water using DCS constitute auxiliary control system, and realize the unification of the network and hardware, and the unit control room is equipped with 2 PC station, but the actual coal and chemical water respectively independent control in coal and water control room. Second, the phase of the set point to point 2. 1 the preliminary design stage 2 project for 2 units of 330 mw coal-fired units, in the first quarter of 2005 and put into production. Using plant-level monitoring information system ( SIS） , the unit of DCS control system, auxiliary workshop automation system and computer network, implementing the centralized control dispersion, information management design principle [ 1] 。 2 sets of fellow 1 unit centralized control room, unit using DCS furnace, machine, electric centralized control. In the ash handling control room, pump room control room respectively by ash, water system control network of the CRT operator station to monitor ash, water system, the auxiliary workshop. Water system control network in the control room in boiler make-up water treatment workshop set up local PC station. In the condensate polishing processing workshop, such as hydrogen production station auxiliary workshop electronics indoor layout workshop CRT operator station. Grey system control network, the electric control system set up PC station to monitor the electric system, the electric control system of PC station CRT with grey system control network operator station layout together, gray system control network CRT operator station monitoring only monitoring functions of the electric system. Coal conveying control system on the basis of one phase of the expansion, and 1 share, not the other. The desulfurization system in the region of the desulfurization using separate desulfurization distributed control system ( 脱硫- DCS） , operators in the FGD control room of the desulfurization system realization by CRT operator station start/stop, operation condition monitoring and adjustment as well as accident treatment, etc. 2. 2 point to adjust according to the preliminary design and thermal control automation system in the course of bidding and construction, to better meet the needs of the actual operation, the preliminary design scheme set up by the monitoring points. （ 1) No separate setup SIS, but according to the huaneng huaiyin power plant construction has been successfully developed using the actual situation of CMIS, on the basis of the original CMIS, on hardware structures, real-time systems, the aim at practical, full and good, save investment and avoid waste. On the software of the original system for secondary development, system integration and upgrade in order to achieve. （ 2) On two ash, water system control network merger, set up the auxiliary workshop control network, the formation of auxiliary workshop control system. Because of ash, water system monitoring in the auxiliary control system implementation, so according to the operation of the actual needs, assist the actual adjustment of decentralizing control system: (1) cancel ash control room, just set to the PC station of local control; After comprehensive pump control room upgrade for the auxiliary control room, (2) according to the actual operation requires only chemical operators operating chemical equipment; (3) the boiler make-up water in PC station located in the original phase 1 chemical ecr, facilitate chemical operators both stage 1 and stage 2 boiler make-up water system operation; (4) to the desulfurization ash control system network control room, on the desulphurization control room 2 additional network PC to realize the monitoring of ash and electric precipitation; (5) in the unit control room reserved auxiliary control system of the network interfaces, such as running you just need to increase 1 on a machine in a unit to control all of the control system of auxiliary monitoring of indoor; 6 as auxiliary control system of coal water and rain water pump room by fuel operation personnel responsible for monitoring control system, using the original phase 1 auxiliary control network of coal to water fiber drew 2) auxiliary control network to coal conveying control room, add 1 stage machine monitoring coal water and rain water pump control system. Three, three phase of the monitory point set is 3 phase has entered the stage of project implementation, planning for the 2 units of 330 mw coal-fired unit, the future will plant a total of six units, the total capacity of 1760 mw. 2) set of point to point also considered the stage 3 factors, the three phase after the factory Settings are point to point.
