Research And Development Of ESP Expert System In Coal Fired Power Plant

ESP is the necessary equipment for dust removal of thermal power plant, it is thefunction of the boiler emissions soot particles in flue gas can be removed, therebygreatly reducing the amount of dust into the atmosphere, which is the improvement ofenvironmental pollution, an important environmental protection equipment toimprove air quality. Expert system of electric precipitator is the knowledgeformalization, organization or level description of electrostatic precipitator systemwithin the domain expert knowledge or experience, the advice of using VisualBasic asthe programming language in the Windows system, fault diagnosis, simulation controlfunction. At the same time, using ACCESS to establish dynamic background database,and knowledge base together to provide dynamic storage and extraction of knowledgein expert system of electric dust collector operation.The consulting help module and fault diagnosis module function need anddatabase or knowledge base to establish a connection, and the knowledge expressionthrough a conditional statement and other call statement; simulation module isthrough the establishment of mathematical model and the related parameters of acoal-fired power plant600MW unit as the basis, process and operating parameters ofdynamic simulation of power dust collector, and simulate the electric field operationmonitoring situation, provide the basis for energy saving operation of electrostaticprecipitator. The expert system for background knowledge management according tothe function module partition, so conducive to knowledge management, easy to add,modify, delete knowledge etc.The expert system software has friendly man-machine interface, convenientoperation and use, from the VB development environment, run independently underWindows, the software can be used for scientific research or coal-fired power plantsimulation training, such as expert at the scene. The research developed a set ofconsultation for help, fault diagnosis and expert simulation control expert system, hasan important role in normal operation and maintenance of electrical precipitator.
