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] Taking a reservoir in the upper reaches of the Yangtze River in my country as an example, for a major flood that actually occurred and caused relatively large flood losses, the calculation of flood control scheduling based on the reservoir area and downstream risk decision-making feedback includes the following steps:

[0090] Step (1) Collection of reservoir basic data.

[0091] Collect information such as reservoir characteristic parameters, reservoir scheduling mode, reservoir water level storage capacity curve, reservoir area and downstream main section basic data, downstream flood control station safety discharge, reservoir area and downstream loss relationship curve, etc., and use it as the basis for reservoir flood control scheduling constraint. There were 31 periods of flood in this field, and each period was 24 hours; there were 70 backwater sections in the reservoir area, which were used to calculate the backwater surface line of the reservoir area, and obtain...

Abstract

The invention relates to a reservoir flood control scheduling calculation method based on reservoir area and downstream risk decision feedback. The method comprises the following steps: (1) collectingreservoir flood control scheduling information; (2) calculating a node time period needing risk decision making according to reservoir flood control compensation flood regulation calculation; (3) starting from the node time period, counting reservoir area return water inundation loss E according to a downstream flood prevention safety decision, and counting downstream inundation loss E 'accordingto the reservoir area flood prevention safety decision; and (4) comparing E with E ', and selecting a flood control compensation scheduling mode. According to the method, the flood loss of the reservoir area or the downstream can be quickly identified, and a decision scheme with acceptable loss is provided for a management department as an optimal scheme.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, in particular to a calculation method for reservoir flood control scheduling based on reservoir area and downstream risk decision-making feedback. Background technique [0002] Reservoir flood control dispatching is a multi-stage, multi-level, multi-objective complex decision-making process, which not only needs to take into account the contradiction between reservoir flood control and profit dispatching, but also takes into account the flood control requirements of cascade reservoir areas and downstream. Due to the real-time, urgency and irreversibility of the reservoir flood control system, it is necessary to make early flood control risk decisions in case of major floods to minimize flood losses. [0003] Most of the current reservoir flood control dispatching is based on the established flood control conditions of the reservoir, and the corresponding outflow flow proc...
