All over more advanced automatic technology and product is used, to improve the competitiveness of power plant.Under such overall background, power plant is certainly
The integral level of dynamicization will enter a new phase, and the integrative coordinated control of machine stove electricity is by new power plant aut omation system
Preferably embodied.Meanwhile IT technologies, field bus technique have an immense impact on to industrial automation, generate electricity
The informationization of factory, digitlization process are accelerated, so as to which merging for the electric and Thermal Automation in power plant is automatic as power plant
The focal issue changed.
The content of the invention
The present invention proposes a kind of large-size thermal power plant electric control system, using distributed system form DCS just

Realize the application functions such as failure wave-recording, protection information management.
The beneficial effects of the invention are as follows：The electric control system realizes the management to electrical equipment and protection information, tool
There is the abundant advanced application function such as equipment control, operation order, anti-error, fault information managing, system autodiagnosis, largely
On improve thermal power plant automation level.
Brief description of the drawings
The ECS that Fig. 1 is the I/O modules of the present invention and hardwire mode is realized.
Fig. 2 is the ECS of the DAS modes of the present invention.
Fig. 3 is the FFCS pattern diagrams of the crucial hardwire of reservation of the present invention.
Fig. 4 is the FFCS pattern diagrams for using communication mode completely of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, traditional being achieved in that of thermal power plant ECS sets single electric controller by ICS（DPU）, through I/O moulds
Part (AI, DI, SOE, IO) realizes the collection and control to electric part.The Special controlling function of electric part, such as relay are protected
Shield, excitation, the same period, power supply switching, failure wave-recording etc. are all completed by independent electric automatics, unrelated with DCS.
The relay protection function of electric part is completed by independent electric protective device, DCS I/O modules with it is electric after
Electric protection works independently, and is not in contact with.All measuring points required for DCS are all come by fasteners such as the AI of I/O in DCS, DI, DO, SOE
Complete, these fasteners only complete most basic acquisition function.I/O parts use cable connection with electric loop, and analog quantity is adopted
Collection needs to install transmitter.
Control system under the pattern has following features：DCS is unrelated with electric protective device；The a large amount of cables of DCS I/O
The collection and control of electrical quantity, cost height are realized with transmitter；The electric I/O points that DCS is obtained are few, and investment is big；It can not obtain
Electic protection action message, conservative management can not be realized；System running state information can not be obtained.
The monitoring to electric part is incorporated on the basis of traditional DCS Thermal Automations, functionally realize thermal technology,
The cooperation of electric specialty, is significant.The pattern realizes preliminary overall-in-one control schema, and then supports DCS and include it
His automated system, is a kind of progress of technology.DCS is realized to electric part key link with its structure, function completely
Measurement and control, so that whole automated system performance gets a promotion.On the other hand, divide completely in DCS and electic protection
From when, protection can use traditional non-Microcomputer Protection, the non intelligentization of protection such as protection using integrated circuit determine that DC S can only
The control of electric part is realized using completely self-contained observing and controlling means.With the development of Microcomputer Protection, electric integrated protection observing and controlling
Device can realize the protection based on AC sampling and digital algorithmic technique, measurement, recording, control and communication, the skill in the field
Art condition and ECS implementation are changed.
Such as Fig. 2, in data collecting system (DAS) pattern ECS, DCS independently realizes electrical control, and ECS is only as DCS's
One data acquisition subsystem, some electric parts I/O information is provided for DCS MMI work stations layer/real-time data base.DCS leads to
Electric current, power (active), the position of the switch, protection signal and related SOE of the I/O to hardwire collection electric loop are crossed,
And realize and the control closed is jumped to motor start and stop/switch.ECS connects wall protection in a manner of fieldbus/EPA
Measure and control device, these devices are considered as to electric DAS I/O modules.ECS realizes the monitoring and management to electric part, communication tube
Reason machine can have part engineer station's function concurrently, realize the application functions such as failure wave-recording, protection information management.
Such as Fig. 3, FECS main station systems hardware configuration is taken by server, communication gate, operator station, engineer station and Web
Business device composition.Web server is apolegamy part, and server and communication gate may operate in same computer, can also divide
Do not set, but need dual, this fractional hardware group screen is placed in electric room.Operator station and engineer station can also select
Select operation to set on the same computer or respectively, according to the application habit of different power plant, FECS operator station, engineer station
The engineer's cab or master control room of control centre can be placed in.
FECS operating rights typically still falls within DCS operator station.DCS can operate through communication to FECS I/O devices,
Start and stop and sequential control including electric part motor and power unit.FECS operator station can be used as DCS operator
The standby stood, in station service electrical system prior to during ICS live line works, the operation of electric part is realized by FECS operator stations.But
With the increase of the advanced application functions of FECS, its operator station can also be as an operator station in master control room.The pattern
Under FECS and DCS overall-in-one control schemas in addition to information fusion, control function has been divided the work.For related to thermal technology's operation
Important Motor Control continues to use DCS I/O hardwire modes, for electric service power part and non-key motor and
The control in loop uses FECS fieldbus/EPA communication mode.
Such as Fig. 4, the pattern further reduces cable, and the scope that FECS participates in DCS controls greatly expands, by pure electrical part
The control (such as power supply) divided expands to the control to 6kV and 380V motor, and then participates in DCS control and behaviour comprehensively
Make.The pattern is a kind of profound overall-in-one control schema scheme, in the control of electrical system implementation process with electric related sensing,
Collection and the correlation function for performing link, FECS participate in control as DCS subsystem.FECS configuration structure and function all bodies
Reveal the process structure for serving DCS and control is accustomed to, so as to have essential distinction with DAS, the up, descending of information is flat
Deng, it is comprehensive.This control model has been made DCS and ECS configuration structure and functional structure in order, made while investment is reduced
ECS is obtained in system configuration and DCS turns into isomorphism system, can be optimal in terms of the fused controlling of two large scale systems.
FECS directly connects day through main control unit (telecommunication management and controller) with the controller of CS structure and DCS, meanwhile, FECS I/
O information can disperse to access DCS, so as to realize overall-in-one control schema from bottom to top.
