摘　　要：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，以这类热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，给出了在供热面积为２０×１０４～３０×１０４ｍ２时，热化系数、热网循环水量、室内散热器面积系数和热网管径增量及热网设计供回水温度的最优值；以及在供热面积一定，单一优化变量变化时，对目标函数的影响关系，可供设计与运行管理参考。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.
