Intelligent control system and control method for water conservancy projects to ensure the safety of estuary water supply

Abstract

The invention discloses a water conservancy project intelligent regulation control system and regulation control method for guaranteeing water supply safety of a river mouth. The system comprises an environment element in-situ monitoring module, an environment element information management control module, an upstream remote regulation control module and a downstream local intelligent emergency module, wherein the environment element in-situ monitoring module is used for monitoring hydrology, water power and water environment elements of key positions of an upstream reservoir and a downstream river mouth in real time; the environment element information management control module is used for managing and controlling hydrology, water power and water quality element information of different sources and different types; the upstream remote regulation control module is used for implementing long-distance accurate optimization scheduling on the upstream reservoir in a water supply safety sensitive period of the river mouth to improve overall water supply safety of the downstream river mouth; and the downstream local intelligent emergency module can implement targeted emergency measures in the downstream local position through intelligent response for the implementation effect of the upstream remote regulation control module to ensure water supply safety of emphatically protected water areas of the river mouth.

Description

technical field [0001] The invention relates to the technical field of water supply safety, in particular to an intelligent control system and control method for water conservancy projects to ensure the safety of estuary water supply. Background technique [0002] The estuary is the link between the river and the ocean, often with superior geographical conditions, developed regional economy and large population. Water supply security is an important guarantee for the sustainable development of the regional economy and society, and is also closely related to the daily life of the people. Saltwater intrusion is one of the common hydrological phenomena and dynamic processes in coastal estuaries: Under the joint action of runoff and tidal dynamics, the incoming water from the upstream river mixes with the high-salinity seawater outside the mouth to varying degrees; when the seawater outside the mouth is higher than the water level of the river, the seawater It will pour back in...

Problems solved by technology

For example, the article "Analysis of the Three Gorges Project on Improving the Situation of Salt Tide Intrusion in the Yangtze River Estuary" made a preliminary discussion on how to further increase the Three Gorges Project's resistance to salt water upstream, and suggested that the reservoir should store water in advance and increase the amount of water released in the driest month; "Based on figures The article "Research on the Operation of the Pearl River Water Replenishment and Pressure Salt Reservoir Based on the Basin Model" and the invention patent with the application number 201310075605.2 "Reservoir, Gate Pump Group Combined Salt Suppression Dispatch Method", both discuss the digital model of the Pearl River Basin as the basis and the key control within the watershed. Optimal control method of major water conservancy projects in the Pearl River Basin where the node's minimum salt-inhibiting discharge is the limiting condition. However, the former only involves the research on the regulation scheme of the main reservoirs in the river basin and does not take the non-controlling water conservancy projects of the estuary into consideration, and the latter is not applicable At the estuary with navigable needs

It should be pointed out that the existing technical solutions or model discussions do not provide practical and specific implementation solutions
