Cascade reservoir hydropower station group scheduling control system and method for fish habitat protection

Abstract

The invention discloses a fish habitat protection cascade reservoir hydropower station group scheduling control system and method. The system comprises an information collecting module, a data monitoring module, a habitat simulation module, a scheduling simulation module and a real-time regulation module. According to the invention, the basic information and real-time information of various fish habitats in upstream and downstream reaches of a river are fully combined; through simulation and scheduling simulation analysis of various fish habitats in various river reaches, different ecology assurance rates are set for various river reaches; the relationship between the ecology assurance rates and ecology flow ranges is clarified; the flexibility and efficiency of ecology scheduling control are improved; united ecology scheduling of a cascade hydropower station group is realized; and the fish habitat protection cascade reservoir hydropower station group scheduling control system and method have the advantages of high practicability and wide promotion prospect.

Description

technical field [0001] The invention relates to a cascade reservoir hydropower station group scheduling control system and method for protecting fish habitats in multiple river sections, and belongs to the technical field of engineering operation scheduling in the field of water conservancy and hydropower. Background technique [0002] The optimal scheduling of cascade reservoir hydropower station groups is an optimal scheduling problem of multi-objective, multi-constraint and complex water conservancy projects. Especially for hydropower station systems that undertake multiple tasks such as power generation, water supply, and ecology, the research on optimal scheduling technology and the development of scheduling control systems are of great importance. Certain difficulty. [0003] my country has built hydropower bases on the Jinsha River, the Yalong River, the upper reaches of the Yangtze River, the Lancang River, and the upper reaches of the Yellow River, and cascade reser...

In related research, the patent application number CN201610808570.2 discloses a method of cooperating with the operation of the logger door to control the ecological regulation of cascade reservoirs and improve the spawning grounds of fishes that produce sticky eggs based on the characteristics of the logger door that can flexibly control the temperature of the discharged water. The cascade reservoir control system and method of water temperature and hydrodynamic conditions, "Eco-friendly Reservoir Scheduling Based on Improved Genetic Algorithm" combined with the local conditions of the Jinping cascade reservoir, selected the ecological water demand process of the local Schizothorax schizothorax As the ecological water demand of the river section, the flow ecological constraints of the hydraulic turbines of Jinping I and II hydropower stations are set, but the most suitable ecological flow in the fish habitat model is used as the constraint condition, which ignores the multi-objective problem to a certain extent. Overall consideration, this problem is also pointed out in the conclusion of this article, but the definition of the ecological assurance rate and the formulation and realization of the multi-objective program are not specifically analyzed
