热力系统数学模型自由度分析

Degree of Freedom Analysis of a Mathematical Model for a Thermodynamic System

利用自由度概念对火电厂热力系统进行了系统分析，提出了物流单元模型和结构模型自由度的求取及决策变量的确定方法，可以运用于流程模拟计算的数值特性分析。

By utilizing the conception of the degree of freedom the authors have performed a systemic analysis for a thermal power plant thermodynamic system, presenting a method for evaluating the degree of freedom of a physical stream unit model and structure model as well as for determining decision variables. The above cited method can be employed for the numerical characteristics analysis of on line flow sheet analog calculation.
