Reservoir group flood control capacity distribution method based on maximal variable-weight remaining flood control capacity

Abstract

The present invention discloses a reservoir group flood control capacity distribution method based on a maximal variable-weight remaining flood control capacity. According to the technical scheme of the invention, serial cascade reservoirs are adopted as equivalent reservoirs and the parameters of the equivalent reservoirs are determined. The weight of the remaining flood control capacity of each reservoir in a serial cascade reservoir group is calculated. According to the weight of the remaining flood control capacity of the serial cascade reservoirs, the weight of the remaining flood control capacity of each reservoir of all equivalent reservoirs is calculated. After that, a reservoir group flood control capacity optimization distribution model based on a maximal variable-weight remaining flood control capacity is established. The model is solved and a flood control capacity optimization distribution scheme is obtained. According to the technical scheme of the invention, the influence of flood characteristics on the reservoir group flood control capacity optimization distribution is fully considered. According to the reservoir inflow, the flood control capacity and the flood routing process, the weight of the remaining flood control capacity of each reservoir is determined, wherein the weight is varying along with different scheduling periods. The influence of subjective factors during the weight setting process of the conventional method can be avoided. The distribution scheme of the reservoir group flood control capacity is optimized and the overall effect of improving the flood control effect in a reservoir drainage basin is realized. The flood control risk of the reservoir is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of reservoir group dispatching, and more specifically relates to a method for allocating flood control storage capacity of a reservoir group with the largest remaining flood control storage capacity based on variable weights. Background technique [0002] When encountering heavy rain with high intensity and concentrated rainfall time, a large amount of rainwater will quickly flow into the river, causing the water level of the river to rise sharply, that is, flooding. Reservoir engineering is an important part of the river flood control system. In order to reduce the loss of flood disasters, the scientific and reasonable joint flood control operation of reservoir groups is one of the most effective non-engineering measures. It is of great theoretical and practical value to study the flood control optimal operation of reservoir groups. [0003] Most of the existing flood control optimization dispatches consid...

[0007] 3. In the process of using the existing method of maximizing the remaining flood control storage capacity, the determination of the weight of the remaining flood control storage capacity of each reservoir depends on human subjective judgment, and the determination of the weight varies from person to person and there is no scientific basis for calculation
