The online calculation device comprises an online calculation application server, and is characterized in that: one end of the online calculation application server is connected with a production data port through a positive isolation device and a data acquirer, and is also connected with a coal quality data port, and the other end of the online calculation application server is connected with a web client platform. The online calculation device is mainly applied to the online calculation of the fire coal quality index and boiler efficiency of the thermal power plant.
Description
Technical field
The utility model relates to a kind of online calculation element, relates in particular to coal-fired coal index of a kind of thermal power plant and the online calculation element of boiler efficiency.
Background technology
For responding the policy requirements of national energy-saving and emission-reduction, strengthen thermal power station's administration of energy conservation level, present most of thermal power plant has all set up SIS (thermal power plant's level of factory supervisory system).The major function of SIS is that realization unit production process information is monitored in real time, utilizes computer technology and modern thermal power plant level of factory supervisory system Energy saving theory, and production data is carried out analytical calculation, is optimization production, and saving energy and reduce the cost provides guidance.It carries out in line computation and analysis through I/O point data and ature of coal analysis data on collection DCS (scattered control system) dispatch control system.
In short supply at electric coal instantly, mix and burn the many and ature of coal of coal and change under the situation greatly a difficult problem that runs in the untimely SIS of the becoming application process of ature of coal analysis data.In addition, coal data burns to adjust to the operations staff and can play good reference role in real time, plays important effect to keeping the unit safety economical operation.Enforcement according to a plurality of power plant is understood, and coal data all is per tour or laboratory values every other day.In view of a variety of causes such as apparatus expensive etc., ature of coal on-line monitoring appearance is not promoted on a large scale and is used.
Existing coal-fired coal elemental composition on-line analysis calculation element is through on coal conveyer belts, installing moisture additional basically; Ash content and volatile matter survey sensor; Through these on-line measuring devices, measure the numerical value of corresponding coal index respectively, thereby the on-line measurement of realization coal index.Prior art is in particular in several aspects such as cost is high, and equipment is installed and the circuit difficult arrangement, and is difficult in maintenance, and efficient is low realizing still there is obvious deficiency aspect the calculating of fired power generating unit coal index on-line monitoring.
Summary of the invention
The purpose of the utility model is to provide coal-fired coal index of a kind of thermal power plant and the online calculation element of boiler efficiency, to overcome above-mentioned drawback.
For realizing above-mentioned purpose; The technical solution of the utility model is: coal-fired coal index of a kind of thermal power plant and the online calculation element of boiler efficiency; Be included in the line computation application server; It is characterized in that: an end of described online computing application server links to each other with the production data port through forward spacer assembly, data gather computer, also links to each other with the coal data port, and the other end links to each other with the web client platform.
The beneficial effect of the utility model is: utilize existing production real time data of thermal power plant and ature of coal experimental analysis data; In conjunction with basic energy conservation and industry standard computing formula; The advantage that the performance computing machine is handled data, realize coal-fired coal index of thermal power plant and boiler efficiency in line computation.This online calculation element can be understood the fundamental characteristics of boiler fired coal ature of coal for the production management personnel of thermal power plant, is to optimize boiler combustion, promotes the unit safety economical operation to provide important references to instruct, and is convenient to manage production, and improves productivity effect.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are done further explain.
Referring to accompanying drawing; The utility model is included in the line computation application server; It is characterized in that: an end of described online computing application server links to each other with the production data port through forward spacer assembly, data gather computer, also links to each other with the coal data port, and the other end links to each other with the web client platform.
The DCS in described production data port and thermal power plant safety I district (being Distributed control system, scattered control system) links to each other through communication line, and production data port, data gather computer and forward spacer assembly are arranged in safe I district; The SIS in coal data port and thermal power plant safety III district (being supervisory information system, thermal power plant's level of factory supervisory system) links to each other through communication line, and the coal data port also is arranged in safe III district; Online computing application server and web client platform are arranged in thermal power plant safety III district, and wherein online computing application server comprises real-time data base server, relational database server, web server and four ingredients of calculation server.
At first, the industries process control system DCS in safety I district monitors the real-time status information of operation unit in real time, comprises each item index parameter of boiler side boiler circuit, air and flue system and pulverized coal preparation system.Data gather computer collects these production real time datas through the production data port by some cycles from DCS, these index real time datas outwards are transferred to safe III district through the forward spacer assembly from safety I district.The coal data port is gathered the ature of coal analysis data from SIS simultaneously.Production real time data that collects and the unification of ature of coal analysis data are called the basic calculation data.The function of forward spacer assembly is to guarantee production control system safety, makes data enter into safe III district from safety I district smoothly, and can not back transfer.This has just constituted the data collection layer of system.
Then, the basic calculation data of coming from data collection layer get into safe III district, get into online computing application server, and are stored in the real-time data base, call in order to calculation procedure.Calculation server be used for participating in coal index and boiler efficiency in line computation, it is divided into a plurality of computing units, comprises the coal-supplying amount computing unit, as received basis moisture meter algorithm unit, as received basis ash content computing unit, boiler efficiency computing unit etc.The foundation that calculation server calculates is the basic calculation data in the real-time data base, and the intermediate data result of calculating and the logical relation between the index are kept in the relational database with the form of form, calls in order to subsequent calculations use and system program.This is a digital data processing layer part, mainly accomplish data storage, analysis, calculate, call and back-up job.
At last, the result of data computation is through the online calculated value of web client shows genset boiler fired coal coal index and boiler efficiency.Web server in the online computing application server mainly is for the web client provides back-office support, and order and request that the web client is sent respond.This external system also has auxiliary function application module, and inquiry, statistics, real-time exhibition and alarm function are provided, and makes things convenient for the user to grasp the real-time condition of production of unit better, and formulates corresponding production management strategy.
