Low-impact emergency ecological dispatch method and system for gate and dam groups based on adjustable capacity

Abstract

The invention provides a low-impact emergency ecological scheduling method and system for gate and dam groups based on adjustable capabilities, which can effectively improve the ecological benefits of a watershed. The low-impact emergency ecological dispatching method of the gate and dam group includes: Step 1. Establish an evaluation system for the emergency dispatching and adjustable capacity index of the gate and dam group for the purpose of ensuring the ecological flow of the key control section of the watershed: 1. Evaluation index selection: from the perspective of water quantity, water quality and engineering These three elements select appropriate evaluation indicators to build an evaluation index system for emergency dispatching and adjustable capacity of sluices and dams with the goal of ensuring the ecological flow of key sections of the watershed; The optimal combination weight of the index; 3. Calculation of the adjustable capacity, and calculate the adjustable capacity value of the gate and dam; Step 2, generation and optimization of the low-impact emergency ecological dispatch plan for the key control section of the gate and dam group in the watershed: 1. Ecological water shortage Calculation; 2. Generation and optimization of emergency dispatch plan.

Description

technical field [0001] The invention belongs to the technical field of gate and dam dispatching, and in particular relates to a low-impact emergency ecological dispatching method and system for gate and dam groups based on adjustable capabilities. technical background [0002] River ecological flow refers to a certain flow process that needs to be maintained in the river course in order to maintain the natural hydrological characteristics of the river and the structure and function of the ecosystem. Ensuring ecological flow is of great significance to maintaining the health of rivers, serving national water security and ecological civilization construction. However, in recent years, the rapid development of economy and society and the deepening contradictions of water resource shortage have caused ecological water to be occupied by production and domestic water, and the diversity of aquatic organisms and even the integrity of river ecosystems have been severely damaged. In ...

Problems solved by technology

However, the current research on ecological regulation focuses more on the construction of medium- and long-term optimal ecological regulation models, and the control object often focuses on a single reservoir, which cannot meet the overall planning requirements of the river basin management department.

From the overall perspective of the gate and dam group in the river basin, there are few studies on emergency ecological dispatching.
