In 2023, the Ministry of Water Resources will successively issue documents such as the Guiding Opinions on Accelerating the Construction of a Modern Reservoir Operation and Management Matrix and the Pilot Work Plan for the Construction of a Modern Reservoir Operation and Management Matrix, clarifying the overall requirements and technical requirements for the construction of pilot reservoirs and pilot areas, so as to provide a basis for comprehensively promoting the construction of a modern reservoir operation and management matrix.
The "Key Points of Water Conservancy Project Operation and Management in 2024" clearly proposed: quickly build a modern reservoir operation and management matrix. Vigorously promote the first and first trial. Comprehensively promote the implementation of full-coverage, all-factor, all-weather, and full-cycle "four-pronged" management in pilot reservoirs and pilot areas, improve the "four systems (governance)" system of system, mechanism, rule of law, and responsibility system, strengthen the "four precautions" measures of forecasting, early warning, rehearsal, and pre-plan, strengthen the "four management" work of risk removal, physical examination, maintenance, and safety, strengthen digital empowerment, actively explore paths, take the lead in achieving breakthroughs, and achieve phased results.
How to build a modern reservoir operation management matrix?
Focusing on the modern reservoir operation and management matrix with the "four comprehensive" management, "four systems (governance)" system, "four pre-planning" measures and "four pipes" as the core content. The "four comprehensive" management of reservoirs has been fully realized, the system and mechanism of modern reservoir operation and management, laws and regulations and technical standards have been perfected, the "four precautions" measures for large, medium-sized and medium-sized reservoirs with key flood control and "a basin of water on the head" have been fully implemented, the long-term mechanism of "four pipes" has been established and improved, the safety of reservoirs has been effectively guaranteed, the benefits have been fully exerted, the modern reservoir operation and management matrix has been basically completed, and the precision, informatization and modernization of reservoir operation and management have been basically realized.
Four-Faith digital twin reservoir solution accelerates the construction of reservoir operation and management matrix
Based on the "reservoir management system", Four-Faith has built a comprehensive solution for digital twin reservoirs, guided by the actual business needs of reservoirs, using digital twins, Internet of Things and other technologies, integrating reservoir data resources and water conservancy professional models, and fully realizing the management matrix functions of "four comprehensives", "four systems (governance)", "four pre-planning" and "four pipes" of reservoirs.
"Four Complete"
1. "Three lines of defense" for rainwater monitoring and forecasting
Through real-time monitoring, forecasting and early warning of the rainwater situation of the reservoir, it helps to speed up the construction of the "three lines of defense", and carries out real-time dynamic monitoring of the reservoir area and downstream rivers. Combined with the hydrological model, data governance platform and digital twin platform independently developed by Xiamen Four-Faith, the whole chain simulation of "rainfall-runoff-confluence-evolution" is carried out to achieve the effective unity of extending the flood prediction period and improving the accuracy of flood forecasting.
2. Dam safety monitoring
The dam safety monitoring system grasps the water level, dam deformation, dam leakage and other information of the reservoir in real time, and realizes the comprehensive grasp of the upstream and downstream, left and right bank elements of the reservoir. Assist reservoir managers to understand the real-time operation status of reservoirs, discover potential safety hazards in time, and provide scientific basis for decision-makers to take timely measures to prevent risks. In case of danger, it can also be broadcast through the early warning broadcasting system, and the downstream residents can be notified in time to evacuate.
3. Inbound and outbound flow monitoring
By building a reservoir inflow monitoring system, reservoir managers can grasp the real-time water storage situation of the reservoir and adjust the water storage and release strategies in time to meet the water supply demand and the requirements of ecological and environmental protection in the basin in different periods.
"Four Pre-Plans"
1. Digital twin system
With the four predictions of reservoir flood control as the core business, the accuracy of flood forecasting is improved by optimizing the flood forecasting and dispatching module, the effective prediction period of flood forecasting is increased, the downstream inundation situation is simulated by combining one-dimensional and two-dimensional hydrodynamic models, and data support and auxiliary decision-making are provided for flood control and disaster disposal through scheduling plans and emergency disposal.
2. Model platform
The main focus of the model platform is on flood control and dam project safety.
Flood control scheduling: Construct a hydrological forecasting model for flood forecasting, a reservoir discharge scheduling model, and a two-dimensional hydrodynamic model for downstream flood inundation analysis with flood control scheduling as the core business
Dam engineering safety: Construct a dam structure safety model with dam structural safety as the core.
3. Knowledge base
The knowledge file contains information such as the plan database, the knowledge graph database, the business rule database, and the expert experience database of water conservancy projects.
4. Data governance
Four-Faith data governance platform provides data governance services for the whole process of data quality control, fusion interpolation, and standardized processing, and realizes the detection of abnormal data, the completion of missing data, and the processing of standardized data.
"Four Tubes"
Four-Faith has created a reservoir safety operation platform in view of the problems of difficult reservoir supervision and operation, high management cost, unintuitive data management, and slow emergency response. Through data fusion, big data computing, model analysis, etc., scientific and accurate management is realized, data barriers are broken down, management quality is improved, and solid data barriers are established for security.
The platform has functions such as visual supervision, video supervision, information data management, water level reservoir capacity calculation table, water situation analysis, rain analysis, displacement analysis, infiltration line analysis, inspection and maintenance, gate remote control, early warning broadcast notification, flood four predictions, mobile applications and so on. Help managers to realize the auxiliary data of reservoir risk removal and reinforcement, the informatization of daily inspection work, and the visualization of reservoir maintenance.
