基于优化调度规律挖掘的水库调度运用方案研究

Study of Reservoir Scheduling Program Based on Optimal Scheduling Law Mining

结合常规调度图操作简单、易于指导实际但难以充分发挥水库的运行效益,而优化调度能够充分发挥水库运行效益但难以指导水库实际运行的特点,分别建立常规调度图模拟模型和发电优化调度模型,通过对比两种方案、分析优化运行的结果,挖掘水库运行调度规律,总结出调度图的修正原则,进而得到优化调度图。以某流域两座水库为例进行应用研究,结果表明优化调度图较常规调度图能够获得更优的结果,为优化理论成果应用于水库实际提供了一种新的思路。

The conventional scheduling chart is simple and easy to guide practical reservoir operation, but is difficult to give full play the benefits of reservoir operation. The optima/ scheduling can run the full benefits of reservoir, but is difficult to guide the actual operation. So the conventional scheduling simulation model and generation optimization model are established respectively to compare two schemes and analyze the results of optimization scheme, and then the scheduling law of reservoir operation is mined and the correction principles of scheduling chart are summarized. Finally, the optimal scheduling chart is obtained. The application studies in two reservoirs in a watershed show that the optimal scheduling chart can obtain better results compared with conventional scheduling chart. The optimal scheduling chart provides a new way for the optimization theory applied in reservoir operation.
