Intelligent control system and method for ecological regulation of cascade hydropower station group

Abstract

The invention discloses a cascade hydropower station community ecological regulation intelligent control system, which comprises a multi-source monitoring module, an information management and control module, an intelligent reasoning module, an ecological regulation module and a system maintenance module. The invention also discloses a cascade hydropower station community ecological regulation intelligent control method. According to the technical scheme of the invention, the data of multiple sources are accurately monitored, intelligently integrated, hierarchically managed and controlled. Meanwhile, based on the intelligent allocation function of the multi-target ecological regulation process by means of the intelligent reasoning module, the targeted ecological optimization and regulation for a cascade hydropower station community, with the comprehensive ecological standard-reaching rate to be maximal as the target, is realized. Multiple ecological regulation requirements in the reservoir area, such as tributary algal bloom, sedimentation reduction at the tail of a water reservoir, sand peak during the flood season, the breeding of four major Chinese carps, downstream ecological water compensation and saltwater intrusion at a river mouth, can be fully met.

Description

technical field [0001] The invention belongs to the field of operation and control of water conservancy and hydropower projects, and in particular relates to an intelligent ecological control technology for cascade hydropower station groups. Background technique [0002] my country is the world's largest consumer of water and energy resources, but it is facing a severe situation of resource shortage and uneven temporal and spatial distribution. my country has built many world-class large-scale water conservancy and hydropower projects, which have exerted huge comprehensive benefits in energy security, flood control and drought relief, water resource allocation, transportation and shipping, and have become an important guarantee for the sustainable and healthy development of my country's economic society. As of 2014, my country's hydropower installed capacity has exceeded 300 million kW, and hydropower bases such as Jinsha River, Yalong River, Dadu River, Wujiang River, the u...

Problems solved by technology

[0006] (1) Existing technologies often focus on a single ecological regulation goal, and it is difficult to take into account the algal blooms in the tributaries of the reservoir area, sediment deposition in the reservoir area, natural reproduction of aquatic organisms, ecological water demand in downstream sensitive waters, and salt tide intrusion in estuaries caused by hydropower projects. Comprehensive influence of many aspects;

[0007] (2) The existing reservoir dispatching work is not closely integrated with on-site monitoring technology, and generally only relies on traditional hydrological monitoring methods, which not only have low temporal and spatial resolution of information data, incomplete attributes, etc., but also use complex experimental analysis methods and poor timeliness , there is a lack of a monitoring system that integrates advanced sensing and measurement technologies to automatically obtain water conditions in the basin, power station operation and equipment status;
