用非线性规划方法优化凝汽式汽轮机区域供热参数

应用有约束的非线性规划方法对采用凝汽式汽轮机供热的区域热电厂的供热参数进行优化研究，针对将原住宅小区的集中供热锅炉房改造为采用凝汽式汽轮机低真空供热的热电厂，以这类电厂服务期内净现值（ＮＰＶ）为目标函数，采用转轴直接搜索可行性方向法（ＤＳＦＤ法）编制计算机程序，并应用这一程序对实际工程实例进行计算，给出在供热面积为２０×１０＾４～３０×１０＾４ｍ＾２时，热化系数，热网循环水量，室内散热器面积系数和

Optimization on Parameters of the Condensing Turbine Used for District Heating by Way of Non-linear Programming

The bounding non-linear programming is introduced to optimize the parameters of condensing turbine used in heat and power station for district heating. An engineering example that a pure hot-water boiler heating system was reconstructed at a heat and power station is given, and the maximum Net Present Value (NPV) during the operation of the heat and power station is taken as the objective function.According to the feature of investigated problems, the rotation-axis direct search-feasible direction (DSFD) method was selected, and the software to conduct the optimum parameters and conclusions are useful for the design and management of a generating system.
