Recently, it was learned from the General Office of the Ministry of Water Resources that the project titled "Research and Application of Key Technologies for the Construction of Digital Twin System for Cascade Reservoir System in the Lower Reaches of the Jinsha River" led by CYPC of CTG has been approved as the National Key Research and Development Program. The approval of this project marks an important step taken by CTG in the field of intelligent water resources management, which is of great significance for improving the scheduling management of reservoir system and enhancing flood control and disaster reduction capabilities.

The cascade reservoir system in the lower reaches of the Jinsha River is an important water conservancy project in the Yangtze River Basin. These reservoirs not only undertake multiple tasks such as flood control, navigation and power generation, but also play an important role in the strategic allocation of national water resources. The flood control capacity of four cascade reservoirs, namely Wudongde, Baihetan, Xiluodu and Xiangjiaba, is 15.49 billion cubic meters, accounting for 41% of that of the world's largest clean energy corridor. The total installed capacity of these four cascade hydropower plants is 46,460 MW, accounting for 65% of that of the world's largest clean energy corridor.

The project titled "Research and Application of Key Technologies for the Construction of Digital Twin System for Cascade Reservoir System in the Lower Reaches of the Jinsha River" was launched in 2025. Yang Xu from the Three Gorges Cascade Dispatch & Communication Center, a key member of the project, introduced that the project will make full use of the Internet of Things, big data, cloud computing and other advanced technologies to build a digital twin that is identical to the real reservoir system in the virtual space by means of digital twin technology. This digital twin can reflect the real-time operation status of the reservoir system, including key information such as water level, flow rate and water quality. When the operational status of the reservoir system changes, the digital twin system can immediately give early warnings and provide decision support for management personnel. This project will realize real-time monitoring and early warning of the operation status of the reservoir system, thus providing scientific basis for scheduling management of the reservoir system, and achieving comprehensive perception, accurate simulation and scientific decision-making of the reservoir system.

Yang Xu stated that it is necessary to take into full account the complexity and uncertain factors of the reservoir system in the process of building the digital twin system. Therefore, the Three Gorges Cascade Dispatch & Communication Center will strengthen data collection and monitoring to ensure the accuracy and reliability of the digital twin system, thus making explorations for the national undertakings of water resources management, flood control and disaster reduction.
