摘要
扰动理论是网络(图论)热经济学的研究方法之一,本文用扰动理论研究了火电机组热力系统,导出了与等效焓降法一致的公式.由于采用了矩阵分析方法,公式导出严格,物理意义明确,便于记忆,有利于等效焓降法的推广,本文对等效焓降的限制条件也做了深入讨论.
This paper presents the power plant thermodynamic system by use of small disturbance theory and derives a set of equations which are identical with those of equivalent euthalpy drops. Because matrix analysis method is used, the equations are derived exactly and have definitive physical meaning. Then, the equations are convenient to remenber and to extend the method of equivalent enthalpy drops. The confind conditions of equivalent enthalpy drops are also discussed deeply.
