The utility model relates to branch works monitoring technique field, generating plant, relates in particular to the system that centralized supervisory is carried out in a kind of operation, control, management that is used for the branch works of generating plant.
Background technology
It is domestic in recent years that large-scale (the single-machine capacity 600MW～1000MW) appearance of thermal power plant, power plant's automatization level day by day improves, and the monitoring and the management of branch works proposed new requirement.
The fuel-burning power plant branch works typically refers to: Boiler water Feeding System system, condensed water precision processing system, water purifying processing system, Waste Water Treatment, recirculated water medicine system, domestic sewage processing system, hydrogen generating system, flying dust system, remove slag system, electric dust removing system, fuel storage system, coal handling system (comprising harbour, coal yard, coal cracker, bunker bay, belt transloading equipment and black water treatment facility) etc., the former control mode on the spot that all adopts, each branch works is provided with pulpit on the spot, and the fixing operation of relative set operator on duty.
Because large-scale unit branch works technology subsystem controls point is many, method of operation difference is big, realize reducing cost of investment and personnel reduction and enlargement, just must improve the automatization level of branch works.
The branch works monitor mode of domestic design before this generally is: of the same type, connatural branch works control system is linked to be relative centralized control net by data communication method, generally be divided into the network of rivers, coal net, grey net, at relative set water, coal, grey centralized control room on the spot, each pulpit all is provided with fixing operation operator on duty.The branch works that the network of rivers connects has: Boiler water Feeding System system, condensed water precision processing system, water purifying processing system, Waste Water Treatment, recirculated water medicine system, domestic sewage processing system, hydrogen generating system etc., and its operator station is arranged in the water centralized control room; The branch works that ash net connects has: ash disposal system, remove slag system, electric dust removing system etc., its operator station is arranged in grey centralized control room; The branch works that the coal net connects has: fuel storage system, coal handling system etc., operator station are arranged in defeated coal centralized control room.On water, coal, grey centralized control net basis, be linked to be branch works control net (BOP) again by data communication method, the operator station of BOP net is arranged in unit control room, be used for operation monitoring, so that the unit operation personnel understand the ruuning situation of branch works, concrete schematic network structure is seen accompanying drawing 1, and this mode has the complicated network structure, failure rate height, investment is big, the operation operator on duty is many and weak point such as cost height.
The utility model content
At above-mentioned the problems of the prior art, the purpose of this utility model is to provide a kind of can reduce the reference mark, thereby reduces the operator on duty, reduces the branch works supervisory system of operating cost; This system comprises: several branch works control system, data communication interface, unit central station of floating dock, the operator station that is provided with in described unit central station of floating dock; Described operator station carries out Centralized Monitoring by described data communication interface to described branch works control system.
Particularly, described branch works control system comprises: Boiler water Feeding System control system, clean water treatment control system, wastewater treatment control system, recirculated water control system for adding drugs, remove ash handing system, slagging-off control system, electric dust removal control system, oil-firing pump house control system, coal handing system.
Described branch works control system is the computer network that is made of programmable logic controller (PLC) and industrial control computer; Described branch works control system all adopts the programmable logic controller (PLC) of same train.
Described data communication interface comprises two switches, described branch works control system all is connected to this two switches, and described operator station reads the data message of branch works control system by described data communication interface and to branch works control system sending controling instruction.Even a switch so wherein is out of order, operator station can also come each branch works control system is monitored by another switch; Reliability is higher.
Because the utility model is connected to operator station with all branch works control system by data communication interface, operator station carries out Centralized Monitoring to the branch works control system, make the reference mark reduce widely, thereby reduced the operator on duty, reduced operating cost.
Description of drawings
Accompanying drawing 1 is the schematic network structure of existing a kind of generating plant branch works supervisory system;
Accompanying drawing 2 is a kind of generating plant of the utility model branch works supervisory system structured flowchart in one embodiment;
Accompanying drawing 3 is a kind of generating plant of the utility model branch works supervisory system schematic network structure in one embodiment.
Embodiment
With reference to figure 2, the branch works control system 3 shown in the figure comprises: Boiler water Feeding System control system, clean water treatment control system, wastewater treatment control system, recirculated water control system for adding drugs, remove ash handing system, slagging-off control system, electric dust removal control system, oil-firing pump house control system, coal handing system.
Operator station 1 carries out Centralized Monitoring by each subsystem in 2 pairs of branch works control system 3 of data communication interface.Wherein operator station 1 is arranged in the unit central station of floating dock, and operator station 1 is made up of two functions enough powerful redundant each other server and graphoscopes, can also comprise utility appliance such as printer; Wherein data communication interface 2 comprises two redundant each other host exchanges; Even a switch so wherein is out of order, operator station can also come each branch works control system is monitored by another switch; Reliability is higher.
With reference to figure 3, the branch works control system computer networks that are made of PLC (Programmable Logic Controller) and industrial control computer that adopt are formed more, the utility model is united the PLC that each main branch works control system of full factory is adopted, adopt the PLC hardware device of same producer same train, and unified communications protocol and database format.On this basis, adopt redundant star topology Ethernet mode, two enough powerful redundant each other servers of function pass through the host exchange of two cables and two redundancies, carry out data communication with each branch works control system, read the I/O information of the branch works control system that is connected, generation comprises whole monitored pictures of the branch works control system that is connected, and the real time data that all read is left in the database of operator station setting.Operator station is with the server of C/S frame mode visit branch works control system, and the branch works control system that is connected is monitored and controls.The steering order that operator station sends reaches each branch works control system through host exchange, finishes the Long-distance Control to all branch works equipment.Operator station is arranged in the unit central station of floating dock, and the branch works scene is only established operation and patrolled and examined all-in-service station, has so just really realized full factory Centralized Monitoring; Make the reference mark of full factory reduce widely, thereby reduced the operator on duty, reduced operating cost.
