China is the world's leader in water resources. However, the utilization rate of this type of energy is only 34 percent, which is much lower than in developed countries - 60-70 percent.
The Woodongde hydropower project, located in the lower reaches of the Jinsha River, between Liuguan County (Yunnan Province) and Gudong County (Sichuan Province), will be the fourth largest hydropower plant in China when it comes into operation.
The installed capacity of the plant will be 10.2 GW, and its annual capacity will be 38.93 billion kWh. The total amount of investment in the project is estimated at approximately $ 15 billion.
The Woodongde hydroelectric power plant, which is called the "smartest" mega-hydroelectric power plant in the world, will start operating in July 2020.
Located in southwest China, the hydropower plant is being built using advanced intelligent technology, including real-time temperature monitoring and intelligent cementing equipment, making it the smartest power project in the world and demonstrating the highest level of intelligent construction in the dam industry in China,
The Woodongde hydropower plant has built-in thermometers and cooling tubes in the concrete to determine the concrete temperature in real time. With the intelligent water supply system, the flow can be automatically controlled to intelligently implement the concrete cooling process.
The 2.8 million cubic meters of concrete in the dam uses low-temperature cement, which can withstand large temperature fluctuations that can cause concrete to crack and jeopardize the safety of the dam, which is a global problem in hydropower, media reported.
The temperature of concrete is 7.1 C at the construction site, and the air temperature is 29 C.
The hydroelectric power plant is the first dam in the world that fully uses low-temperature cement.
The Woodongde hydropower plant is designed as a concrete arched arch with a maximum height of 270 meters. The foundation thickness of the dam is only 51 meters, which makes the hydropower plant the thinnest 300-meter arched dam in the world today. The "thin" concrete will be able to store about 7.4 billion cubic meters of water in its tank.
The length of excavation of the main workshop of the underground power plant at the Woodongde Dam broke the world record with the height of 89.8 meters, which is equivalent to a 30-storey building.
The hydropower plant will be able to produce 38.9 billion kilowatts of electricity per year once its 12 units are operational. It is expected that the first unit will start operating in August 2020.
The first batch of generating units should be put into production in July 2020, and the project should be fully completed in December 2021.
A total of 12 units on the plant, each Francis Turbo Generator with a capacity of 850 MW, will generate power. Six turbogenerators with a capacity of 850 MW.
The turbogenerators for Woodongde will be one of the largest in the world and will also be the largest that have been supplied in terms of output power.
As clean energy, the amount of hydropower generated by Woodongde will save 12.2 million tons of standard coal and reduce carbon dioxide and sulphur dioxide emissions by 30.5 million tons and 104,000 tons annually.
Chinese are always better than rest of the world in some way. So I am not surprised of this. But any way, very good writing this is.
