东西湖区水利系统排涝优化调度

根据东西湖水利系统排引灌的逻辑关系 ,对该系统进行了合理概化 ,并以涝灾水量最小为目标函数建立了东西湖区排涝优化调度模型 .由于闸门的操作具有“0 ,1”特性 ,使优化模型形成一种二维、一维混合模型 ,大大地增加了模型求解的难度 .通过将二维状态离散点进行顺序组合的方式 ,将二维问题转化为一维问题 ,从而顺利地完成了计算

Optimal operation of drainage for water conservancy system of Dongxihu District

Based on the logic relation between drainage and irrigation of the Dongxihu water conservancy system, an approximate simplification of the system is outlined, and optimal operation model with the objective function regarding the lowest waterlogging, is established. Sinice gate control with ‘0,1’ characteristic, the optimal model is formalized as a mixed model of two dimension and one dimension, and it greatly increases difficulties for solving the model. By way of the combination in ordinal number of the discrete points of two dimension states, the mixed model is transformed into one dimension problem and the solution is worked out successfully.
