摘要
提出了一个适用于计算机软件开发的电站热力系统通用矩阵模型,并编制了程序,通过实例计算验证了模型的正确性。该模型基于热力系统的结构特征矩阵和回热加热器的“通断系数”,对加热器的结构特征进行了高度的抽象,全面考虑了回热加热器类型、换热器效率以及各种辅助汽水等因素。该矩阵模型结合了组态思想,算法可靠,通用性强,适用于大型火电机组的热经济性分析计算,为电厂实时监测和分析软件的开发提供了方便的工具。
A general matrix model for thermodynamic systems of power plants, applicable for computer software development, is being proposed, a program composed, and the model＇s correctness vindicated by calculating some practical examples. This model, which is based on the structural characteristics of thermodynamic systems and switching coefficients of regenerative heaters, highly abstracts the structural features of the heaters, and takes full account of the type of heater used,as well as its efficiency and the influence of auxiliary systems. The matrix model conforms with the configuration concept, the way of calculation proposed is reliable and generally applicable, suitable for analyzing and calculating the thermo-economic efficiency of large fossil fired power generating units, therewith providing ＂a facile tool for developing real time monitoring and analyzing software. Figs 3, table 1 and refs 8.
