What is the development prospect of China's water conservancy and hydropower

Water conservancy, as an integral part of the national economic system, has a special and important position in China, playing a fundamental role in preventing floods and maintaining safety, supporting economic and social development, and maintaining the health of natural ecology.

River and lake environment of the beautiful and livable construction is a long way to go, rivers and lakes is the main carrier of water resources, with self-purification, guide the flow of water, protection of the environment, moisturizing the land, to make up for the groundwater a series of functions in the natural ecosystem has a unique role, is the natural world and the human society to maintain the functioning of one of the most important elements. In recent years, rivers and lakes in the provision of basic water sources on the basis of its environmental functions are increasingly being emphasized, the unique natural ecology of the river and lake environment, meandering, nourishing forests, regulating the climate and other aspects of the characteristics of the river and lake environment make the river and lake around the land environment more suitable for human survival and development. Green mountains are gold mountains, the river and lake environment plays an important role in "green water", is to enhance people's high quality of life indispensable natural environmental resources, river and lake environment improvement and maintenance will be our country in the new historical development stage and later long-term development of the important needs.

Improvement of the river and lake environment includes the adequacy of the water volume in the river, the amount of water maintained in comparison with the historical water volume, the safety of water quality, the degree of hydrophilicity of the shoreline, the integrity of the vegetation, as well as the main flora and fauna, and the improvement of the water environment within the watershed and so on, especially for the complexity of China's topography, the diversity of geomorphology, and other characteristics, the construction of the ideal river and lake environment of the livability of the task is very important and a long way to go.

The current water conservancy project enterprise management will become the mainstream of water conservancy project operation and management, with the increasing number of water conservancy projects, and gradually establish the corresponding technical specifications for project management, the establishment of efficient, low-cost and safe mode will be the key issue to face in the future. Visualization technology combined with GIS, particle simulation, virtual reality, edge computing and other technologies, digital twinning Minjiang River Basin Water Conservancy Project, realizing real-time monitoring of dams, embankments, spillways, sluices, channels, water crossings, rafts, fish passages, hydroelectric power stations, water quality, the environment, water level, rainfall and so on, and realizing sustainable use of hydraulic resources.

Using 3D configuration to restore the power production process, monitor the running status of the unit, and improve the efficiency of power generation. Supporting the integration of various video resources to form a unified video stream, Hightopo's self-developed digital twin technology correlates the video signal sources from the top of the dam, the generator level, and the cameras in the power distribution room. Through the scene interaction to retrieve the corresponding monitoring video, to meet the real-time situational awareness of the operation and maintenance personnel, historical data back to the comparison and other needs.

After entering the main plant, you can freely roam around in first-person view (W A S D arrow keys combined with mouse operation), and view the detailed operating parameters of the generator, the camera monitor screen, and other information. It supports drawing and saving common inspection routes, and automatically roams according to the fixed routes after each entry to meet the personalized inspection needs. Through the process of inspection simulation or inspection car inspection, you can stop to view the equipment information when passing through the equipment.

Large hydroelectric power stations are characterized by large installed capacity, affecting regional power supply. Once the station's reservoir, dam (including sub-dam), power plant house, diversion canal and other failures, will cause extensive power outages, seriously affecting the harmony and stability of society. The intelligent security system of the hydroelectric power station associates the monitoring signal source in the station, displays the on-site monitoring screen, monitors the regional intrusion, smoke and fire, failure, etc., and guarantees the good operation of the facilities and equipment in the station.3D Icons in the scene can be clicked to view the corresponding monitoring screen, personnel name, alarm time, and alarm details.

The 2D interface is labeled with camera distribution, video statistics, behavioral analysis alarms, station personnel distribution, personnel alarms and other information. Through the visualization system, the video surveillance system, entrance and exit management system, intelligent one-card system, intrusion alarm system, operation process management system, perimeter water detection system and emergency command system can be integrated and managed.

Collecting DOM (Digital Orthophoto) and DEM (Digital Elevation Model) data within the river basin, and based on the real urban river status information and surrounding scenery information, the 3D spatial data of the river channel and river bottom are modeled in 3D geometry; then the finely modeled hydroelectric power station model is superimposed and rendering optimization is carried out; and finally, the rendering is carried out by using display lists, texture priority, detail level model (LOD) and other rendering techniques to realize real-time realistic virtual scene display of 3D river and provide rich means of human-computer interaction.

It can simulate the change of the shoreline around the river flow according to the historical water level data, which helps to judge the critical value of the water level and regulate the water level in advance to prevent flooding or notify the surrounding residents to move in advance.

Based on the collected historical data of water quality of river streams and reservoirs, the HT cloud rendering technology is used to take out a certain section of three-dimensional waters, and the high and low water quality data is displayed in a three-dimensional cloud map, and supports the operation of the timeline, inverting the changes in water quality throughout the year. According to the inversion data, we can judge the content of chemical residues in the water, the salinity in the water, the salt content of the downstream river water, the number of schistosomes in the water, the number of microorganisms and bacteria, and the number of aquatic plants and algae. When serious water quality problems occur, timely remedial measures are taken.

At present, water conservancy projects of a single nature are becoming more and more refined, resulting in numerous individual projects of very small scale, but the preliminary work of project establishment is still complex, so how to reasonably set the size of the project in order to enhance the speed of project establishment and management efficiency has become **** knowledge. In addition, mountains, water, forests, fields, lakes and grasses are interconnected as a whole, suitable for integrated management, there are also many projects themselves have comprehensive characteristics, with a variety of uses, such as the top of the dam of the reservoir is a major traffic artery, the reservoir has become a lake, a lot of projects covering the water resources of the whole industry chain links merged to carry out, unified management, and so on.
