| In this paper, the research background and the domestic and international study status are expatiated. To demonstrate by Meishan reservoir, the time average reservoir inflow hydrograph of Meishan Reservoir isrotton is work out. the Characteristic Curve of reservoir and other curves are drawn up by Cubic Spline.The routine shedule model, the optimal flood model, and the optimization schedule model which based on MATLAB are established with the series of the reservoir water level, the time average reservoir outflow, water utilization and so on. Using Dynamic Programming algorithm, taking the maximum energy of the cascaded hygropower station in the whole operation times and considering guaranteeing power as subject, this section presents a cascaded hygropower station economical optimized operation model.The calculating results show that the models are reasonable and the results of optimized operation is better than the results of the original one. New theory is provided for the increase of utilization factor of water resources of the western region of Anhui Province.Finally, study results of the whole paper are given, and then in allusion to the shortage of this article contents, some study to be further studied are presented. |
