Embodiment 1

[0024] A method for optimizing a flood dispatching scheme, comprising the following steps:

[0025] Step 1: Classify the flood according to the magnitude of the flood. The basis for the classification is: all the reservoir projects in the watershed fail to reach the design standard flood level when preventing floods, and this flood corresponds to the flood magnitude of the river basin. When the flood prevention reaches the design standard flood level, this flood corresponds to the basin flood level II; when any reservoir project in the basin prevents floods, the reservoir water level exceeds the design standard flood level, then this flood corresponds to the basin flood level III;

[0026] According to the characteristics of super-standard floods in the basin, the magnitude of super-standard floods is a process that changes with time. The development process of super-standard floods is divided into three stages, which correspond to flood magnitudes (Ⅰ, Ⅱ, and Ⅲ).

[0027] Step...

Embodiment 2

[0108] Taking the middle reaches of the Yangtze River Basin as the research object, the flood control system projects involved in flood control dispatching include Xiluodu, Xiangjiaba and Three Gorges Reservoirs.

[0109] Adopt the decision tree of the scheme construction of embodiment 1. Among them, the decision tree of flood magnitude II is as follows: Figure 5 shown.

[0110] Forecast the typical 1% flood of 1954 in the middle reaches of the Yangtze River Basin (current flood level is II, design standard flood, flood type 1), according to the first branch of the decision tree and the forecasted flood type 1, find the standard flood peak or The second branch corresponding to the flood volume; the current water level of Xiluodu, Xiangjiaba and Three Gorges Reservoirs is Combination A. According to the water level and storage capacity curve, the current remaining flood control storage capacity accounts for 80% of the flood control storage capacity, and the corresponding wate...

Abstract

The invention discloses a method for optimizing flood dispatching schemes, which comprises step 1: classifying floods according to flood magnitude; step 2: screening and establishing a set of basic schemes of a decision tree; step 3: establishing correspondences for three sets of flood dispatching schemes Decision tree of each flood level, step 4: apply the decision tree to make real-time flood control dispatching decision. The invention is a decision-tree-based optimization method for a superstandard flood dispatching plan, which can realize rapid selection of a flood control dispatching plan and provide technical support for real-time flood dispatching.

Description

technical field [0001] The invention relates to a method for optimizing a flood dispatching scheme, belonging to the technical field of water conservancy engineering, in particular to the technical field of flood early warning and flood control, in particular to superstandard flood dispatching, and in particular to a method for optimizing a flood dispatching scheme based on a decision tree. Background technique [0002] Flood disasters in my country are sudden, frequent and uncertain, and their threat to human survival and development is relatively serious, especially the disasters caused by super-standard floods are even more immeasurable. The flood control engineering system formulates multiple scheduling schemes when dealing with floods, and chooses which scheme is the best. The intelligent and fast optimal scheme has become the key technology for flood control decision-making. [0003] Most of the existing river basin flood control schemes are optimized for reservoir eng...
