| 摘 要： | 建立了基于统一模型和计算原则的汽轮机耗差计算方法:首先对火电机组的所有组成部分在工作点处进行线性化,建立各个组件的简化模型;然后提出耗差分析计算过程共同遵守的计算原则;最后以4个蒸汽参数为例,详细解释了模型和原则的使用.经实例验证表明:基于统一模型和计算原则的耗差计算可以达到快速清楚地使用变工况手段计算汽轮机有关参数耗差的目的,有效指导汽轮机不同参数变化下的耗差计算.

| Abstract: | An energy-loss calculation method has been developed for steam turbines based on unified models and calculation rules,in which simplified model for each component of thermal power plant was first established by linearizing all the components at their working point,and then calculation rules for energy-loss analysis were proposed that should be obeyed during all calculation processes.Taking four steam parameters as an example,a detail explanation is presented to how to use the models and rules.Actual applica... |
