摘　　要：负荷优化分配是火电厂运行优化的一个重要研究领域,在机组之间合理地优化分配负荷能够提高整个火电厂运行的经济性。为此,提出一种利用MATLAB曲线拟合工具箱和优化工具箱进行机组负荷优化分配的方法,利用该方法对机组负荷分配中的线性规划和二次规划进行了比较,同时对通过仿真计算得到的图形和数据进行了对比,直观得出了二次规划比线性规划具有更优的分配结果的结论。该分配方法具有简洁、快速、节能效果好的特点。Optimized load distribution is an important subject in the operation optimization of a thermal power plant, Rationally and optimally distributing loads among units can raise the economical efficiency of the whole power plant. This paper presents a method for optimized load distribution among units based on the curve fitting toolbox and the optimization toolbox of MATLAB. Quadratic programming distribution and linear programming distribution are contrasted by the method. It is obviously shown by simulation and calculation that quadratic programming distribution gets more optimal results than linear programming distribution. The proposed method is simple, practical and with good energy conservation effect,
