Description
Technical field
The present invention relates to a kind of cement mill integrated safe protection control system, especially cement clinker DCS, cogeneration DCS, the unified integrated integral control system of steam turbine control protection DEH.
Background technology
Present domestic cement mill is because problems such as fund, technology; Cement clinker line and cogeneration production line mostly are not to build simultaneously; Even build the same period, because cement belongs to different industries with the power station, desired robotization professional technique is different, the control system that is adopted neither same brand; Even the system of same brand also is two systems fully independently.Steam turbine DEH (electro-hydraulic control system), ETS (emergency trip system) all are to be accomplished by the supporting producer of boiler because professional technique requires highlyer at present in addition, with cogeneration DCS isolated island system fully independently especially.External at present owing to professional division refinement more, and because the investment of cement factory cogeneration is very little, and the steam turbine protection control technology is very difficult, so external above three systems also are fully independently!
From production technology; Cogeneration is an auxiliary workshop section of the ripe line of cement; Can not be as traditional power station independent operating; And current domestic and international situation is; Who knows that cement line DCS, cogeneration DCS, steam turbine protection control system DEH, ETS are three fully independently automation control systems, and in process of production clinker cement operator and cogeneration operator also independent fully, do things in his own way, so often take place influence that cement quality is unstable, problem such as output decline, cement clinker energy consumption are increased because of multiple electricity; The equipment failure of clinker cement line also often takes place cause cogeneration unusual fluctuations to occur, the cogeneration operator phenomenon that unable to make head or tail of takes place.
In sum; Clinker production line, cogeneration, turbodynamo are the indivisible integral body of factory; And be whole factory workshop arranged side by side, the objective requirement of multiple as far as possible electricity is set out under the constant situation of collateral security grog output, quality, assurance cement clinker energy consumption, reduces the angle of operation total cost from factory; From improving DCS property easy to maintenance; From improving the real angle of whole factory benefit, offer as a tribute social perspective from energy-saving and emission-reduction, whole DCS in factory system integration be inevitable trend, historic choice.
Summary of the invention
The deficiency of do not share in order to overcome existing clinker cement line DCS, cogeneration DCS, steam turbine protection control DEH, three system datas independently of one another of ETS, man-machine interface disunity, control not being interlocked; The present invention provides the integral control system of a kind of same database based on whole factory, same EPA, same DCS/PLC software, same softwarecompatible DCS/PLC hardware, same man-machine interface; Be that clinker cement line DCS, cogeneration DCS, steam turbine protection control DEH, ETS are the different control stations of same system; Through overall data library inquiry data, failure judgement, problem analysis; Realize that through an EPA exchanges data, control interlocking, blind spot show, realize coordinated operation, guarantee the realization of process strategies and production management through same man-machine interface; Guarantee device security, long-term, steady running; In addition through unified planning, implement step by step and also reduced construction cost, reduce the staff, reduce labour intensity.
The technical solution adopted for the present invention to solve the technical problems is: from design; Cement clinker DCS, cogeneration DCS, steam turbine control protection DEH, ETS are carried out synchronous integrated design; Adopt the control theory in " territory "; Be that clinker cement workshop section, cogeneration workshop section, steam turbine control protection workshop section are as whole DCS in factory systematically different " territory "; Through shared same operating platform, same EPA, same database, same compatible brand system hardware; Realize data sharing, resource sharing, coordination control, chain operation, thereby realize partial operation, global monitoring, stabilised quality, raising output, energy saving purposes.
From enforcement, can be synchronous, also can implement a certain " territory " step by step, thereby realize whole standardized integral control system.Clinker cement " territory " by raw material control station, calcining kiln tail control station, burn till the kiln hood control station, the cement grinding mill control station is formed; Cogeneration " territory " is made up of boiler control station, turbodynamo control station, utility appliance control station; Steam turbine control protection " territory " is made up of DEH, ETS control station.
Field layer: the site intelligent bus apparatus adopts Profibus DP communication standard and cpu controller to communicate;
Control and management layer: adopt the EPA ICP/IP protocol to realize the communication between system controller and the active station; Separately between each layer connect each other again, connect through computer network system, to reach the decentralised control of DCS, the purpose of centralized management.
It is EPA that control in control, the cogeneration in engineer station, the clinker cement, clinker cement field control " territory ", cogeneration field control " territory ", steam turbine protection " territory " are inserted enterprise's backbone network.Adopt the EPA ICP/IP protocol to realize the communication of enterprise's backbone network, backbone network can be star topology, ring topology, also can be bus type topological structure.
Controlling a shared station server in control and the cogeneration in the clinker cement is the engineer station; Clinker cement field control " territory ", cogeneration field control " territory ", steam turbine protection " territory " are sent to server through EPA with signal data; Signal data is delivered to each active station through after the server process, by the operator production line is kept watch on control.Because shared same station server is regulated the DEH system with the steamer mechanical electronic hydraulic and is connected directly to EPA with steam turbine emergency trip ETS system, directly reads the steam turbine full detail by server, in operator station, realize no blind spot demonstration.Realized the shared fully of data message; Grog line operative employee also can keep watch on other workshop sections of this line and the turbine parameters of cogeneration line in this workshop section of operation; The cogeneration operator also is that so he can only operate this generating workshop section, but can keep watch on whole factory.Control no longer separately like this in the grog line in control and the cogeneration, do things in his own way.In order better to guarantee clear definiton of powers, the operative employee of our station has operation and keeps watch on authority our station, and its station is only had the supervision authority, does not have operating right.
The invention has the beneficial effects as follows; Guarantee that cement clinker line DCS, cogeneration DCS, steam turbine control protection DEH are the different control stations of same system,, realize that through an EPA exchanges data, control interlocking, blind spot show through overall data library inquiry data, failure judgement, problem analysis; Realize coordinated operation through same man-machine interface; Guarantee the realization of process strategies and production management, guarantee device security, for a long time, steady running, in addition through unified planning, implement step by step and also reduced construction cost; Reduce the staff, reduce labour intensity.
