摘要
以现代计算手段为依托,在“先归并,后分析”的分析思路指导下,结合等效热降理论和q-g-t 矩阵,构造了能效分布矩阵方程,该矩阵方程全面反映了机组主系统和各种辅助系统对机组热经济性的影响状况,每个矩阵物理意义明确、规律性强。该矩阵方程的矩阵分析方法适用于各种凝汽机组的热经济性分析计算,具有通用、精确和适应计算机程序化的特点,可以使热力系统的热经济性整体计算和局部分析变得更加清晰、简单、客观,非常适合于计算机程序化。最后对所述方法,通过实例进行了验证。
Based on the combination of equivalent heat drop method with the q-g-t matrix, a power-efficiency distribution matrix equation is derived from the point of view of 搈erging first, and then analyzing? by means of modern calculation, which reflects the effect of thermal economy on main system and auxiliary system all-round-way, and each matrix has a explicit physical sense and strong regular form。The matrix analysis method based on this matrix equation can be used in analyzing thermal economy in all kinds of the condensing power unit. It's versatile, accurate and suitable for computerization in thermal system calculation and local analysis. An example is given to illustrate validity of the method.
