摘　　要：提出了一种使用LMS(Least-mean-square,最小均方)算法来构造电站燃料增益和热量信号的方法。该方法通过LMS算法建立机组给煤量和锅炉有功功率之间的输入输出模型,依据抽头权值之和来构造燃料增益。在机组获得给煤量信号的基础上,构造了热量信号。在对机组实际运行数据进行分析之后,证明了构造的燃料增益和热量信号具有动态响应速度快、稳定性好、准确度高,有较好的工程实用价值。Proposed was a method for forming fuel gain and heat quantity signals for a thermal power plant by using LMS(least-mean-square) algorithm.The method in question was used to establish a model controlling the input and output between the coal feed quantity of the unit and the active power of the boiler and the fuel gain was formulated by the sum of the tape weighting values.On the basis of obtaining a coal feed quantity signal of the unit,a heat quantity signal was formed.After an analysis of the practical op...
