Study On The Thermal Power Unit Economic Operation Expert System

In the environment of electric power market, it is very important to realize the optimization operation of the thermal power unit, which could decrease the energy cost and increase the utilization coefficient of energy in our country. To carry on economy analysis to the running situation of the thermal power unit is favorable to achieving the safety, reliability, economy operation of power plant, And with the use of expert system technology, the complicated problems could be solved, which are difficult to be solved In the power system.The thesis introduces the structure and construction of the thermal power unit economic operation expert system, which is on the basis of analysis of thermal economical performance. When the thermal economical performance is made, the main economy index of boiler, turbo-generator and Auxiliary equipments is calculated and showed in real time. And at the same time, diagnosis and analysis to the running state based on the running parameter are provided. The knowledge base of the expert system is constructed with producing rules, and the inference engine is forward reasoning.The thermal power unit economic operation expert system is independently developed with the Borland Delphi language. It has a good human-machine operation interface and good expansion, with several monitor figures. It also can provide the analysis and guidance advice of experts in this field to the operation of power unit, with some health diagnosis ability.
