摘要
通过对双抽汽式汽轮机的耗量特性进行较全面分析的基础上,针对双抽汽式汽轮机耗量特性数学模型难以确定的问题,提出一种新的方法。该方法是利用辅助截矩曲线和最小二乘法进行耗量特性工况图的曲线拟和,然后构造耗量特性曲线方程和相应的约束条件。此数学模型为热电厂和电力系统的经济调度提供理论依据。算例试算表明方法有其实用性。
On the basis of analysis to the consumption characteristics of double-extraction turbine,this paper proposes a new method for the difficult problem of determining the mathematic model of consumption characteristics.The method formatted the consumption characteristic curve and its constraints by aid intercept curve and lease square method.An accurate mathematic model of consumption characteristics function can be used in the economic dispatching of cogeneration power plant and electric power systems.Example test shows the method is feasible and practical.
