In order to promote the upgrading of the energy structure, China is vigorously constructing hydropower stations. Recently, China has taken another shot and created a super project on the cliffs. It is a new construction in China. And the Wudongde Hydropower Station that has been put into use, and the completion of this hydropower station, directly won the title of the world’s seventh hydropower station. Relying on power generation alone, this hydropower station can make billions in a year for China. The Wudongde Hydropower Station is just a hydropower station built by China on Jinsha River. There are still many hydropower stations under construction or in the planning state. It is conceivable that hydropower will occupy the proportion of China’s energy structure in the future. a big part.

Wudongde Hydropower Station is located at the intersection of Yunnan and Sichuan provinces. The high mountains and deep valleys have always been regarded as the nightmare of infrastructure projects, but it is precisely Because of the large terrain drop and the Jinsha River flowing through it, it is very suitable for the construction of hydropower stations. If the abundant hydropower resources can be effectively used, China's energy structure will also be improved as a result, avoiding thermal power generation. Standing in the dominant position in the proportion of China's energy structure, because compared with thermal power stations, hydropower is a renewable energy source and does not produce carbon dioxide, which can effectively avoid the aggravation of 's greenhouse effect, which is worth mentioning The problem is that after the completion of the hydropower station, it can be put into continuous production, and the thermal power station needs to continue to introduce coal after it is completed to be able to generate electricity. Therefore, in the long-term cost, the price of thermal power is also more expensive than hydropower. With the increase in the amount of hydropower, This move will also help maintain China's low electricity prices.

As early as ten years ago,China has successfully completed the Three Gorges Dam , and the completion of this dam has eliminated the problem of electricity shortage in eastern China, especially in rural areas, the situation of regular power outages in the summer has been greatly improved. This is precisely It is the credit of the hydropower station, and now with the development of science and technology, China’s demand for electricity has begun to increase substantially. Under the premise of restricting thermal power generation, the deep development of hydropower has become the best choice in China, and the Wudongde Hydropower Station is precisely what It was born under this background.
This hydropower station is by no means a simple hydropower station. As the fourth hydropower station in China and the seventh in the world, the dam of this hydropower station reaches 270 meters in height, lying in the valley, blocking the flow of the Jinsha River. , Thus forming a huge drop, this hydropower dam is not only high in height, and the thickness of the bottom of the dam is only 51 meters, so it becomes the world’s thinnest ultra-high dam, and it is also the world’s first full dam to use low-heat cement The super-high arch dam made of concrete has created a new world record. With the continuous increase of the water storage height of the dam, the arch dam needs to block the 8.09 million tons of thrust formed by the water body in the reservoir area. I want to use such a thin dam. To block the huge water pressure in the reservoir area, the difficulty can be imagined.

At the same time, in order to meet the demand for power generation, this hydropower station has installed 12 advanced generator sets with a total installed capacity of 10.2 million kilowatts. Approximately 40 billion kilowatt-hours of electricity can be produced each year. With the continuous debugging and optimization of the hydropower station in the later period, and the upgrading of the generator set, the power generation of this hydropower station is expected to rise to a higher level, thereby creating huge economic benefits for China .
generates 40 billion kilowatt-hours of electricity a year, so what is this concept? Take Shanghai, the city with the largest electricity consumption in China, as an example. This city consumes about 160 billion kWh of electricity a year. A Wudongde hydropower station can meet Shanghai's quarter of the electricity demand, coupled with wind power generation and new construction. Nuclear power plant,The power security in eastern China can be guaranteed. With the continuous improvement of the power transmission project from west to east, these hydropower stations in the west will become the hematopoietic stem cells for China's economic development.
