Problems solved by technology

In fact, in the face of major floods, in the practice of real-time flood control dispatching of reservoirs, there will often be an embarrassing situation in which the backwater in the reservoir area is submerged and the excess flood in the downstream is difficult to deal with. The submergence risk of flood diversion in the downstream reaches, how to make dispatching decisions has become an important problem for flood control personnel

Embodiment 1

[0089] Step (1) reservoir basic data collection.

[0090] Collect reservoir characteristic parameters, reservoir scheduling mode, reservoir water level and storage capacity curve, reservoir area and downstream main sections

[0091] Step (2) calculates the node period that needs to make risk decision-making according to the flood control compensation and flood regulation of the reservoir.

[0094]

[0100]

[0101] Do this until all calculation periods are complete.

[0102] The flood control process of the reservoir under the two scheduling decisions is shown in Figure 4 below, including the water level process and the flow process. It can be seen from Figure 4 that

[0103] Step (4) the optimal output of the decision-making scheme.

Abstract

The invention relates to a reservoir flood control scheduling calculation method based on reservoir area and downstream risk decision-making feedback, which comprises the following steps: (1) collecting reservoir flood control scheduling information; Node period; (3) From the node period, count the backwater submersion loss E of the reservoir area according to the "downstream flood control safety" decision, and at the same time count the downstream inundation loss E' according to the "reservoir flood control safety" decision; (4) compare E and E', select the flood control compensation scheduling method. The method can quickly identify the flood damage in the reservoir area or downstream, and provide the management department with an acceptable loss decision-making scheme as an optimal scheme.

Description

A calculation method for reservoir flood control dispatch based on risk decision feedback of reservoir area and downstream technical field The invention belongs to the technical field of water conservancy and hydropower, particularly relate to a kind of decision feedback based on reservoir area and downstream risk. Reservoir flood control scheduling calculation method. Background technique [0002] Reservoir flood control scheduling is a multi-stage, multi-level, multi-objective complex decision-making process, which must take into account the reservoir flood control. Contradictions with Xingli dispatching, and overall consideration should be given to the flood control requirements of the cascade reservoir area and downstream. Due to the flood control system of the reservoir Real-time, urgent and irreversible, so that in the event of a major flood, it is necessary to make flood control risk decisions in advance, so as to maximize the reduce flood damage. [0003] The ...
