摘　　要：等效焓降方法是热力系统节能分析的一种局部定量分析方法,其核心是抽汽等效焓降的计算,抽汽等效焓降的传统算法是一种串联算法。本文研究抽汽等效焓降的矩阵算法模型,不仅为等效焓降的并行运算创造条件,而且将热力系统的"形"与矩阵形式的"数"建立了对应关系,扩展了等效焓降的理论基础。根据抽汽等效焓降的定义,建立了与热力系统结构特征相关联的矩阵模型。算例表明,抽汽等效焓降的矩阵模型具有物理意义明确、数学描述简捷、便于并行计算等特点。The equivalent enthalpy drop method(EEDM) is a partial quantitative analytical method for energy-saving analysis of thermodynamic system, the main point is to calculate the extraction equivalent enthalpy. Extraction equivalent enthalpy is traditionally considered to be a serial method and not suitable for parallel calculation. This paper makes a study of algorithm of matrix model for extraction equivalent enthalpy drop. It not only creates conditions for parallel calculation but also builds the corresponding relationship between the thermodynamic system and the matrix and it extends the theoretical foundation. This paper builds the matrix model for corresponding structural characteristic of thermodynamic system according to the definition of extraction equivalent enthalpy. Samples show that the matrix model for extraction equivalent enthalpy drop has the characteristic of clear physical meaning, sententious mathematic description , convenient to parallel calculation and support for optimal analysis.
