Energy Efficiency Diagnosis of Boiler Island Operation Based on Data Mining Technology
In order to solve the problem of energy efficiency diagnosis of boiler island under the background of thermal power unit peak load adjustment,this paper constructed the energy efficiency reference base based on data mining technology,and established the energy efficiency diagnosis mod-el of boiler island under different operating conditions combined with the consumption difference fac-tor theory.Taking the load,coal quality and ambient temperature as the external constraints of boil-er island operation,the historical operation data is divided into working conditions by the improved K-means algorithm.The operating conditions with the best energy efficiency state among similar operating conditions construct the energy efficiency benchmark condition library;By analyzing the deviation degree between the operating conditions and the benchmark condition,the evaluation of the operating energy efficiency of the boiler island is realized,and the benchmark condition library is up-dated.Based on the coal consumption deviation and consumption difference factor of energy efficien-cy characteristic parameters,the energy efficiency of boiler island operation can be analyzed layer by layer,so as to obtain the specific reasons for the deviation of energy efficiency,which is convenient for operators to make timely operation adjustments.
