摘　　要：将复杂非线性蒸汽动力系统参数优化扩展到热电联产流程结构和蒸汽参数的联合优化，提出的混合整数非线性规划（ＭＩＮＬＰ）模型包含非凸非线性费用目标函数、复杂非线性过程约束及多方案选择的组合优化０－１变量逻辑约束．应用算例表明，所采用的模型和改进的遗传算法解决热力系统组合方案优化问题是可行的．? A mixed integer non linear programming (MINLP) model is presented for structure optimization of steam power systems. The presentation accounts simultaneously for the non convex non linear cost function, the complicated relations of steam properties, the constraints of turbine work generating process, as well as the logical constraints of 0 1 integer variables. By means of the improved genetic algorithm, the results of a numerical example show that the model and the algorithm involved are effective.
