Study on the Algorithm of Power-efficiency Distributing Matrix Model for Thermal System for Power Unit with Double Reheat

研究的热力系统能效分布矩阵方程是在常规热平衡法、q-γ-τ矩阵形式和等效焓降等基础上提出的。能效分布矩阵方程中的每个矩阵物理意义明确、规律性强,可以使热力系统的整体计算和局部分析变得更加清晰、简单、客观。算例表明,能效分布矩阵模型具有物理意义明确、数学描述简洁、便于并行计算等特点。

The power-efficiency distributing matrix equation for thermal system studied in this article is developed on the basis of conventional thermodynamic methods, q-γ-τmatrix and equivalent enthalpy drop. Each matrix of the power-efficiency distributing matrix equation has a explicit physical sense and strong regular form, which makes it simple, clear, objective for global calculation and local analysis in thermal system. Samples show that the power-efficiency distributing matrix model has the characteristic of clear physical meaning, sententious mathematic description and convenient to parallel calculation.
