Abstract

The invention discloses a reservoir-capacity-compensation-method-based method for flood resource utilization of cascade reservoirs. The method comprises: step one, calculating the surplus storage capacity of an upstream reservoir; step two, according to a water level running state of the upstream reservoir, determining a water level running state of a downstream reservoir; and step three, realizing flood resource utilization based on a compensation relationship between flood control capacities of cascade reservoirs. According to the invention, the requirement on the flood forecasting is low; the occurrence time of the next flood does not need to be considered; the water level running state of the downstream reservoir is determined only based on the water level running state of the upstreamreservoir; the worry about uncertainty caused by the flood forecasting is avoided; the full rate of the reservoir is increased; the flood resources in a flood season can be utilized as much as possible; the power generation efficiency is increased; and the operability is enhanced.

Description

technical field [0001] The invention belongs to the technical field of flood resource utilization, and in particular relates to a cascaded reservoir flood resource utilization method based on a storage capacity compensation method. Background technique [0002] Flood itself is a natural phenomenon. Whether or not it causes disaster depends to a large extent on the intensity and mode of human activities in addition to the natural attributes of floods. That is to say, not all floods will cause disasters. When the magnitude of the flood has not exceeded a certain critical value, it is a kind of resource. Through a series of measures, the flood can be converted into water resources, which is flood resource utilization. . At present, the flood resource utilization methods widely used in reservoirs mainly fall into the following categories: [0003] (1) The method of retaining and storing the flood tail at the end of the flood season. In the flood receding section, the reservoi...
