The invention discloses an unattended control system for a waste heat recovery power station. The system is provided with a power generation self-adaptive coordination control function, an expert knowledge base function, a comprehensive alarm function, a short message sending function, an unattended caution function and an automatic backup function. The system is capable of reducing the working intensity of running and maintenance personnel, intelligentized and fully-automatic, and capable of realizing a real unattended operation.
Description
Technical field
The present invention relates to a kind of power domain, specially refer to waste heat recovery power station unmanned control system.
Background technology
Waste heat recovery power station generally adopts video monitoring, interactive mode at present, but substep, enforcement in batches mostly, each territory independent operating of generating production line, each territory needs independently monitor staff, system be unable to do without artificial monitoring, intervention, cannot accomplish real full-automation running, realize unmanned, virtually reduce the high efficiency of system, increase the operation management cost of power house.
Summary of the invention
The object of the invention is to for the problems referred to above, propose a kind of waste heat recovery power station unmanned control system, to realize, hand labor intensity is little, operating cost is low, realize intelligent automation and the high advantage of work efficiency.
the technical solution adopted for the present invention to solve the technical problems is:
The present invention includes used heat and produce territory, boiler hot switching domain, steam turbine territory, generator territory, central controller, comprehensive alarm device, message release platform, monitoring camera-shooting assembly, wherein, unattended system controller adopts PLC Programmable Logic Controller, system adopts two PLC redundancy structures, when a PLC wherein can automatically switch to another PLC after breaking down, do not affect power station operation, and immediately issue failure message to supervisor.This system is the Opening DCS system of new generation towards factory automation, supports field bus technique comprehensively, and system adopts global data base technology, realizes Global Uniformityization programming.System communication is standard ethernet, and system architecture has more flexible ability, and System Programming adopts international standard IEC61131-3.Field control station adopts intelligent I/O fastener, carries out data communication by Profibus DP agreement and fieldbus instrument equipment, and modular design, has extremely strong compatibility.
System controller built-in power generation self-adaptation coordinating control module, expertise library module, integrated alarm module, message release module, unattended alarm module, automated back-up module, wherein:
Generating self-adaptation coordinating control module: according to process concatenation control relevant between multiple domain, can realize unmanned, automatic operating electricity generate function, according to system plug-in, this module can, according to used heat flow, heat content, temperature, pressure, composition fluctuation automatic power generation adjustment amount, can be adjusted waste heat recovery power station front end, backend process according to waste heat recovery power station unusual condition automatically.
Expertise library module: relevant stock of knowledge generates electricity in built-in abundant used heat generation territory, there is fuzzy reasoning function, if system monitoring occurs to fault, expert system can be out of order and produces reason and provide corresponding solution according to abundant knowledge base according to the immediate inference of fuzzy reasoning function;
Integrated alarm module: module has that fault gives warning in advance, integrated alarm function, expert system can omnidistance monitoring field electricity generation system service data (pressure, temperature, flow, rotating speed, generated output), can find in advance the unusual condition of emerged in operation according to abundant knowledge base deposit, and then infer the reason of unusual condition occurs, and provide corresponding solution, there is the function of giving warning in advance, the incidence of minimizing accident; If system monitoring occurs to fault, can give the alarm by sound equipment, light, notify maintainer to carry out fault eliminating.
Message release module: system is provided with message release platform, if generation systems fault and unusual condition, the platform very first time is issued note to corresponding power station supervisor, to find in time fault and to get rid of, short message content is failure message, fault occurrence positions, issuable reason and corresponding solution; Platform in accordance with regulations time at intervals date of issue generated energy, generated output per hour to power management personnel, to carry out the statistical work of power station generated energy.
Unattended alarm module: by following the trail of with positioning radiography device and tracing positioning device, the personnel that sound prompting is strayed into leave as early as possible, and the number entering is carried out to mug and analytic statistics.
Automated back-up module: power house service data (gauge pressure, temperature, flow, rotating speed, generated output, generated energy, failure message, alert event, disposition, the time that enters pulpit personnel take pictures) is carried out the omnidistance backup of filing in real time by this module, related data formation curve, histogram, and be uploaded to the computer system of upper level competent authorities, and show on monitor screen, support that person in charge has access to inquiry at any time.
The invention has the beneficial effects as follows, system can alleviate operation and maintenance personnel's working strength, intelligent full-automatic, realizes real unmanned, cut payroll to improve efficiency, and safety in production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
It in figure, is network topological diagram of the present invention.
In figure: 1. system controller, 2. generating self-adaptation coordinating control module, 3. expertise library module, 4. integrated alarm module, 5. message release module, 6. unattended alarm module, 7. automated back-up module.
Embodiment
The present invention includes used heat and produce territory, boiler hot switching domain, steam turbine territory, generator territory, central controller, comprehensive alarm device, message release platform, monitoring camera-shooting assembly, wherein, unattended system controller adopts PLC Programmable Logic Controller, system adopts two PLC redundancy structures, when a PLC wherein can automatically switch to another PLC after breaking down, do not affect power station operation, and immediately issue failure message to supervisor.This system is the Opening DCS system of new generation towards factory automation, supports field bus technique comprehensively, and system adopts global data base technology, realizes Global Uniformityization programming.System communication is standard ethernet, and system architecture has more flexible ability, and System Programming adopts international standard IEC61131-3.Field control station adopts intelligent I/O fastener, carries out data communication, modular design, favorable expandability by Profibus DP agreement and fieldbus instrument equipment.System controller built-in power generation self-adaptation coordinating control module, expertise library module, integrated alarm module, message release module, unattended alarm module, automated back-up module.
