Today (28th) at around 6:55 in the morning, the first batch of units of the Jinsha River Baihetan Hydropower Station completed 72-hour continuous trial operation with load, and will be officially put into operation today.
CCTV reporter Zhang Wei:
I'm in the underground powerhouse on the right bank of the Baihetan Hydropower Station. The Unit 14 and Unit 1 on the left bank that you see are undergoing final preparations before they are put into operation.
After the 72-hour trial operation of the two units is completed, they will be handed over to the Baihetan Hydropower Plant and officially put into operation for power generation.
The Baihetan Hydropower Station has installed a total of 16 hydroelectric generating units with a single unit capacity of 1 million kilowatts, which is currently the largest single unit capacity in the world.
It is understood that the electricity generated after the first batch of units is put into operation will be mainly sent to Jiangsu and Zhejiang to help the economic development of the Yangtze River Delta region.
Wang Zhilin, director of the Baihetan Project Construction Department of the Three Gorges Group:
How much electricity can such a huge unit
generate in
one revolution?
According to our calculations, each revolution of the wheel can generate about 150 degrees of electricity, which is
equivalent to the electricity consumption of an ordinary family in one month
.
A single unit can generate nearly 17,000 kWh per minute.
Baihetan Hydropower Station is located in Ningnan County of Sichuan Province and Qiaojia County of Yunnan Province on the lower reaches of the Jinsha River. The total installed capacity of the power station is 16 million kilowatts, second only to the Three Gorges Project and second in the world. The annual average power generation capacity is 62.443 billion kWh. All units will be put into production in July 2022.
Million-kilowatt hydro-generator set achieves a breakthrough
For the
first time,
Baihetan Hydropower Station
adopts a million-kilowatt-level hydro-generator set entirely designed and manufactured by China,
which has achieved a major breakthrough in China's high-end equipment manufacturing.
What is the concept of a single machine capacity of one million kilowatts?
This means that a Baihetan hydro-generator set can generate 1 million kilowatt-hours of electricity after one hour of operation.
A total of 16 million kilowatt units have been designed and installed in the entire Baihetan Hydropower Station, all of which are independently developed and manufactured by my country.
Yin Guojun, deputy general manager of Dongfang Electric: The
entire rotating part exceeds 2,600 tons.
After assembly, the operation has realized "zero counterweight".
It meets the requirements of high-quality goods in one startup.
Realize our dream of high quality for millions of units.
Because the Baihetan million-kilowatt unit adopts a number of world-first new technologies, its development is far more difficult than any unit under construction and commissioning in the world, and it is
known as the "Mount Everest" of the world's hydropower industry.
The successful commissioning of the unit will greatly promote the development of the entire hydropower industry, and also sign that my country is gradually becoming the center of hydropower innovation in the world.
Wu Weizhang, Deputy Secretary of the Party Committee and General Manager of Harbin Electric Group Co., Ltd.:
Because we have one million units of technology, we have driven the entire industry chain, including processing equipment and machine tools, as well as raw materials, supporting parts, and so on.
The commissioning of the Baihetan unit indicates that our technology in hydropower generation equipment has reached the world's advanced level. When our country expands this kind of project in the future, the technology is completely in our own hands.
Coming into operation, the comprehensive benefits of power generation hydropower stations appear
Baihetan Hydropower Station is the lower reaches of the Jinsha River, including Wudongde, Xiluodu, Xiangjiaba Hydropower Station, among the four cascade power stations with the largest storage capacity and the most significant cascade benefits. As the first batch of Baihetan Hydropower Station units are about to be put into operation, its comprehensive benefits Will become increasingly apparent.
According to estimates, after the Baihetan Hydropower Station is put into operation, it can save about 19.68 million tons of standard coal and reduce the emission of 51.6 million tons of carbon dioxide and 170,000 tons of sulfur dioxide every year.
By then, the Baihetan Hydropower Station will form the world's largest clean energy corridor together with the Three Gorges Project, the Gezhouba Project, and the Wudongde, Xiluodu, and Xiangjiaba hydropower stations on the Jinsha River.
Fan Xiaxia, deputy general manager of China Three Gorges Corporation: After the
power station is put into operation, the annual power generation will reach 60 billion kWh, providing a steady stream of clean energy for the Yangtze River Delta region. It is a national strategy integrating power generation, flood control, shipping, and environmental protection. engineering.
During the construction and operation of Baihetan Hydropower Station, it not only improved the infrastructure conditions of transportation and communication in the surrounding area of the power station, but also increased local employment by about 80,000 people during the peak period of power station construction. After all units are put into operation, it can contribute about 15.5 billion yuan in industrial added value each year. , To increase local fiscal revenue by 2.9 billion yuan and become a driving force for local economic and social development.

Currently, the Three Gorges Group is coordinating the construction of the beautiful Jinsha River, fully carrying out the construction of the Baihetan public welfare forest, and building an important ecological civilization barrier on the upper reaches of the Yangtze River.
