Since the reform and opening up, China's development has caught up with the United Kingdom and the United States, and many fields have achieved "corner overtaking". Especially in terms of infrastructure, China can be said to be a "ceiling" and a "god-like existence". The world was amazed at this "miracle project" but could not describe it in words, so it called up an "infrastructure maniac" to cover everything and show respect.
"The best architecture comes from China". Beijing Daxing International Airport, the world's largest new airport, the Qinghai-Tibet Railway, the world's highest railway, the Three Gorges Dam, the world's largest power generation, and the world's longest sea-crossing bridge, the Hong Kong-Zhuhai-Macao Bridge. If you talk about it, you can't finish it for three days and three nights.
What I want to introduce to you today is that there is good news again! Wudongde Hydropower Station has been put into operation for power generation, and China's infrastructure has created another "miracle", what is going on?
First of all, let's analyze the reasons for the establishment of hydropower stations
As we all know, China is determined to achieve "carbon neutrality" by 2060. Don't look at 2060, there are still 39 years before us, but the mainland's carbon emissions have exceeded 16 billion tons, and modern society is full of the smell of greenhouse gas emissions. And "carbon neutrality" means that in 39 years, all this will disappear and clean energy will take its place.
As a major thermal power country, this is a protracted hard war. At present, 60% of China's electricity consumption is based on thermal power, and the remaining 40% is supplemented by renewable energy (hydro, wind, solar, etc.). Among them, wind energy and solar energy are two power generation methods that are greatly affected by external influences (weather, day and night, etc.), and the advantages of hydropower at this time are very prominent.
Wudongde, which is as famous as the Baihetan Hydropower Station
Wudongde Hydropower Station, located in the lower reaches of the Jinsha River at the junction of Luquan County in Yunnan Province and Huidong County in Sichuan Province, belongs to the first echelon of four cascade power stations, and the rest are Baihetan, Xiluodu and Xiangjiaba. Since the full start of construction in 2015, it has been fully put into operation in June 2021, and has been firmly in the fourth largest hydropower station in China and the seventh largest in the world.
The project has an installed capacity of 10.2 million kilowatts, and six Francis hydroelectric generating units with a single capacity of 850,000 kilowatts will be installed on both sides of the strait, with an average annual power generation of 38.91 billion kilowatt hours. If calculated according to Beijing's electricity consumption in 2018 (114.238 billion kWh), Wudongde can bear as much as 30% of Beijing's electricity consumption, which is very high-yield.
Jinsha River is located in the Himalayan volcanic seismic zone, with a large water level difference and abundant hydropower resources, so the construction of hydropower stations has great advantages. The advantages are big and the difficulties are also great, the earthquake and flood control can not be bypassed, the geological conditions are complex, the dry and hot valley climate, hot and dry, and the temperature can reach more than 40 degrees, which brings difficulties to the construction.
In order to break the bottleneck, the implementation team continuously screened the building raw materials, and finally created a precedent in the history of dam construction in the world, using low-heat cement concrete. The mixed concrete is quickly sent to the pouring silo surface, and then the temperature of the dam is sensed in real time, and finally the Wudongde Dam is successfully cooled, because it is also known as one of the "smartest" dams in the world.
Wudongde is of great significance, and the Chinese people have been "blessed".
As an important cascade project in the mainland, Wudongde Hydropower Station not only plays a role in generating electricity, but also takes into account flood control, promoting local economic and social development and the poverty alleviation and prosperity of local immigrants, further consolidating the leading position of mainland hydropower in the world hydropower field, and is of great strategic significance to the economic and social development of Sichuan and Yunnan provinces and the "west-to-east power transmission".
This time, China's infrastructure has created another "miracle". What are your different views or ideas about the Wudongde Hydropower Station being put into operation for power generation? Welcome to leave a message in the comment area below to discuss, thank you for reading.
