| description | To make the formulation of the ecological release countermeasures of the reservoir adapt to the flood and dry water coming from the river and the ecological flow guarantee objectives of the Ministry of Water Resources, the ecological regulation release countermeasures model of the reservoir is studied. Taking Baishi Reservoir on the Daling River as an example, the ecological flow calculation results of Tennant method, Texas method and the ecological flow guarantee target (fixed value method) of the Ministry of Water Resources are selected for ecological dispatching to build an ecological dispatching model with optimal water supply, power generation and ecological coordination. There is no requirement to restore the flood limit water level at the end of the dispatching period. The average annual water supply shortage of the three methods are 8.20%, 20.21% and 11.62% less than the requirement to restore the flood limit water level. The average ecological water supply shortage are 16.39%, 14.40% and 10.96% less than the requirement to restore the flood limit water level. The average power generation of the fixed value method and the Texas method are 0.90% and 3.46% less than the requirement to restore the flood limit water level. The average power generation of the Tennant method is 3.73% more than the requirement to restore the flood limit water level. There is no requirement to restore the flood limit water level at the end of the dispatching period. The average annual water supply shortage of the reservoir by Tennant method are 19.91% and 10.69% lower than that by the constant value method and Texas method, the average non-flood season water shortage is 49.47% and 21.17% lower, the average annual power generation is 4.25% and 5.77% higher, and the average flood season power generation is 69.22% and 9.20% higher. At the end of the operation period, the reservoir water level does not need to restore the flood limit water level as much as possible, which can improve the utilization rate of the reservoir water resources. The operation mode of ecological water demand calculated by Tennant method can effectively combine the characteristics of incoming water to achieve the optimization of water supply, power generation and ecology. |
