【摘要】 借助于正交试验设计 ,对某台 2 0 0MW机组燃煤锅炉飞灰含碳量特性进行了多工况热态测试 ,获得了数据样本 ,采用基于Levenberg -Marquardt(LM)算法的BP神经网络 ,建立了飞灰含碳量软测量模型 ,通过仿真计算 ,证明了飞灰含碳量软测量模型的正确性和有效性
【Abstract】 With the help of orthogonal design method,the unburned carbon content in the fly ash of a 200MW units burning coal boiler is tested and data specimens have been gained.Taking BP neural network based on Levenberg Marquardt(LM)algorithm,the soft measurement model of the unburned carbon content in the fly ash is established.The soft measurement model is illustrated with simulator calculation.Calculation results have shown the effectiveness and applicability of the soft measurement model.
