摘要
火电机组优化目标值的合理确定是机组性能监测和优化运行的前提和基础,充分利用电厂生产运行的大量历史数据,将关联规则应用于火电厂优化目标值的确定,建立从数据预处理到规则评估与表示的完整过程模型,并以某1 000 MW机组历史数据作为挖掘对象,运用此方法得到100%负荷下各参数的最优值。
Rationally fixing operation optimization target values of fossil fired power sets is the precondition and also forms the basis for effectuating performance evaluation and operation optimization.One way of establishing optimized systems is proposed by applying data mining technique for making full use of the large amount of historical data stored in power plants.The optimization target of a fossil fired power plant＇s operation was found by applying association rule mining algorithm.As a practical example optimal values for all modes of operation of a certain 1000MW power set were found which may be used for guiding actual operation.
