【摘要】 基于等效热降理论，针对叠置机组热力系统的特殊性，提出了叠置电厂中压机组的功量指标转换系数ξ和热量指标转换系数ψ，利用这２个转换系数能简捷、快速地定量分析叠置机组热力系统变化对机组的经济指标的影响，进而得出了叠置电厂热力系统局部定量分析的数学模型．该模型的概念清晰、结果准确、计算方法与中压机组类型无关，并通过实例验证了定量分析模型的正确性和可行性，从而形成了叠置机组的热力系统的局部定量方法．更多还原

【Abstract】 The equivalent enthalpy drop theory is applied to examine the power conversion coefficient ξ and heat conversion coefficient ψ according to the specific characteristic of superimposed unit. They can be used to calculate the thermo economics indicator variation caused by the thermal system change of middle pressure unit. The local quantitative analysis model of superimposed unit is established, that is diconnected from the type of middle pressure unit. Validation of method is made by working an actual example更多还原
