Description
Technical field
The utility model relates to the branch works control system of the control system of a kind of power plant branch works, particularly a kind of high concentration.
Background technology
Along with further going deep into of electric system reform, the operation that assurance equipment is high-quality and efficient is raised labour productivity, and has increased economic efficiency into the target of power plant's development.Early stage power plant is because controlling level and equipment dependability are lower, most main means that adopt the conventional simulation dial plate as power plant's operation, the pulpit lining is equipped with a large amount of supervisory instruments and action button, many units adopt a centralized control room, need a large amount of cables to enter the pulpit from the scene.
Afterwards, power plant begins to gradually adopt scattered control system (Distributed control system, DCS), but early stage power plant's controlling level and equipment dependability are lower, need the operations staff more, open, stop at unit and operational process in need the operations staff often to arrive on-the-spotly to make an inspection tour and handle problems, control ability is poor in real time; In addition, can not adopt many units to adopt the mode of a centralized control room control because the distance between early stage whole communication network of DCS and communication network two stations is limited.Along with network and development of computer, the performance index of DCS itself are greatly improved, communication distance between whole network of DCS and communication network two stations all increases to some extent, ultimate range between some DCS network node even can reach 2000～4000 meters, the DCS operator station can be arranged in from its process rack centralized control quite far away indoor, can only be arranged near its process rack but not resemble early stage DCS operator station.Therefore, raising along with power plant's automatization level and equipment dependability, now new power plant construction open, stop at unit and operational process in no longer need a large amount of operations staffs and need the operations staff often arrive on-the-spot the tour and handling problem as early stage power plant, and only need a spot of operation personnel on the spot under personnel's the cooperation, just can realize that in central station of floating dock the start and stop of unit are controlled in only a few.
At present, because one or two units are only gone up with first phase by domestic most of power plant, conventional arrangement for the fuel-burning power plant of many installed capacitys mostly is two machines, one control arrangement, being that monoblock adopts the DCS control system, is that the center monitors monoblock and controls with LCD, giant-screen.By taking mode with pulpit and monoblock electronic equipment area apart arrangement, near the electronic equipment that two monoblock DCS process racks are placed on respectively monoblock is indoor, and two monoblock DCS operator stations are located in the concentrated pulpit of a full factory, only a spot of communication cable, power supply and umbilical cable need be arranged from the extremely complete on the spot factory of monoblock centralized control room.Compare the mode that many units are in the past established a centralized control room, nowadays adopt the monitoring of two machines, one prosecutor formula, interfering with each other between the unit is less; Because the pulpit is nearer from two units, can save a large amount of cables; And the operations staff is more convenient from the pulpit to the scene, and it is more timely to handle on-the-spot problem.
But, continuous expansion along with present power plant scale, the raising of generating capacity, the engineering that power-plant engineering is built four units the same period has simultaneously appearred, add the distribution of coal, ash, change water management point, present two machines, one control arrangement need be provided with a plurality of central station of floating docks, and is equipped with more operations staff, do not have the economic benefit that can reach best, can not satisfy the higher requirement of power plant cutting payroll to improve efficiency and improving operations staff's total quality.Therefore, need on the arrangement basis of existing two machines one control, make progressive an improvement, build the power-plant engineering of four units simultaneously the same period with cooperation, and reach better economic benefit.
The utility model content
Technical problem to be solved in the utility model is to provide four machines that have only a centralized control room one control formula power plant branch works control system at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this four machines, one control formula power plant branch works control system, include the branch works subsystem, genset, with the described branch works subsystem network centralized control room that links to each other and control control point in the supplementary set of described branch works subsystem and monitor described genset respectively, it is characterized in that: described genset has #1, #2, #3 and #4 be totally four units, described centralized control room is for monitoring described #1 simultaneously, #2, four machines, the one control chamber of #3 and #4 unit, and the auxiliary centralized control point of each branch works subsystem is arranged in the described four machines one control chamber.
In order to realize the centralized control of four machines, one control, convenient management and raising controlling level, described four machines one control chamber comprises server, engineer station, operator station and large-size screen monitors operator station, and be connected respectively to the optical fiber host exchange and become an entire system, (SupervisoryInformation System in plant level's described optical fiber host exchange SIS) is connected with plant level supervisory information system again.
In order to make The whole control system can cover monitoring to each branch works subsystems such as water, coal, ashes, described branch works subsystem including water and water utilities management system, defeated coal stored program controlled, #1#2 unit condensed water precision processing system, #3#4 unit condensed water precision processing system, #1#2 flying dust control system, #3#4 flying dust control system, grey reservoir area pulp water control system, hydrogen generator station control system, recirculated water control system for adding drugs and other control system.
Described branch works subsystem also include separately sub-switch and programable controller system separately, described sub-switch links to each other by twisted-pair feeder with corresponding programable controller system, and described sub-switch links to each other by optical fiber with described optical fiber host exchange respectively.Thus, above-mentioned four machines can enough be realized centralized control and management to each branch works subsystem once the control chamber by described each sub-switch.
Compared with prior art, advantage of the present utility model is: the arrangement that adopts one control of four machines in the auxiliary Control Network of power plant, effectively networked in genset, branch works subsystem and control point, realize of monitoring and the management of a centralized control room, promoted full factory operation and management level full factory; Owing to reduced the reference mark and the operations staff of full factory, can save operational and administrative expenses; In addition, because the unification of the hardware and software of whole auxilliary control net system has reduced stock's standby redundancy and daily management maintenance cost.And, because cancelled much pulpit on the spot, reduced construction and fixture and fitting fare, reduce the configuration of office facility and operator station on the spot, reduced capital cost like this.
