摘　　要：结合三门峡水库汛期减淤、发电需求的特点,建立了三门峡水库汛期多目标优化调度模型。利用Matlab2009a遗传算法工具箱编制计算程序,将NSGA-Ⅱ算法应用于三门峡水库汛期优化调度模型求解,得到了一系列Pareto最优解,选择较优方案与实际值比较表明,用最优化算法能取得较满意的调度效果,既满足了排沙减淤的需要,又可取得较大的发电量。Based on the introduction of the NSGA-Ⅱ theory, and combining with the sedimentation reduction and power generation requirement characters of Sanmenxia Reservoir during the flood season, the paper set up the corresponding multi-objectives optimum operation model, used the Matlab2009a Genetic Algorithm toolbox to write the relevant calculation program, applied the NSGA- 1I to the optimal operation of Sanmenxia Reser- voir and got a series of Pareto results. The proper result was compared with the practical operational situation. The comparison result shows that the NSGA- Ⅱ result can meet the target to achieve multi-objective reservoir optimum operation. It can not only drop the sedimentation apparently but al- so enhance the power generation value.
