The world‘s largest single-unit capacity Jinsha River Baihetan Hydropower Station’s first batch of generating units put into operation
Correspondent Fu Hongjie Zhang Hong Our reporter Li Liyun Qu Jian
At 8:8 on June 28, the highly anticipated unit 14 on the right bank of the Baihetan Hydropower Station with the largest single-unit capacity in the world successfully carried a load of 1 million kilowatts! This is the world‘s first grid-connected power generation unit and the world‘s first unit to achieve 1 million kilowatts of full-load power generation.
The best of the best
After trial operation test, the guide bearing swing of Unit 14 is within 0.10 mm, which is better than the quality standard; the stator core vibration value, guide bearing bush temperature, thrust bearing bush temperature and other key indicators are also better than the quality standard.
Expert appraisal: Unit 14 on the right bank of Baihetan has become a top quality product!
At this moment, all participants couldn’t help but be moved: the world‘s largest hydropower project under construction and the most technically difficult giant hydropower crown was picked by China! Another “national card” stands out!
As a manufacturer of 8 units of the right bank power station, Harbin Electric Motor Co., Ltd., under the unified organization and coordination of the Three Gorges Group, placed the developed high-quality units on the commanding heights of the world‘s hydropower, leading the world‘s hydropower equipment technology into the “no man’s land”; During the commissioning, it is closely cooperating with China Energy Construction Gezhouba Electromechanical Company. On the occasion of celebrating the 100th anniversary of the founding of the party, I handed in a wonderful answer to the party and the country!
The innovation of Baihetan mega-kilowatt hydropower unit mainly includes two parts: one is that the generator has jumped from the original 800,000 kilowatts to the current 1 million kilowatts, and the second is that the turbine uses long and short blade runners, and at the same time realizes wide load and high efficiency. Stable operation.
On June 28, at the ceremony for the first batch of units of the Baihetan Hydropower Station to be put into operation, Wu Weizhang, deputy secretary and general manager of the Harbin Electric Group, said excitedly: The excellent indicators of unit operation prove that we have firmly grasped the power of this big country. In their own hands. The achievement of the results comes from the strong leadership of the Party Central Committee and the State Council, and from the national position, wise decision-making and systematic command of the Three Gorges Group. Standing at a new starting point, all cadres and employees of the Harbin Electric Group will also take this opportunity to transform the trust of the party and the trust of the country into a strong driving force. Under the leadership of the Three Gorges Group, uphold the concept of the millennium plan and keep the Baihetan project on schedule. Completed the handed down project.
Chasing dreams, white cranes will finally come true
Baihetan Hydropower Station is located at the junction of Ningnan County in Sichuan Province and Qiaojia County in Yunnan Province. It stands on the mainstream of the lower reaches of the Jinsha River. With a total installed capacity of 16 million kilowatts, it is currently the world‘s largest hydropower project under construction. After the power station is completed, the average annual power generation will reach 62.443 billion kWh.
The development of all eight 1 million-kilowatt hydroelectric generating units on the right bank of Baihetan is a result of the successful development of the Three Gorges, Xiluodu, Xiangjiaba and other giant hydroelectric generating units by the Harbin Electric Group, once again relying on first-class technical strength and superior manufacturing quality. Excellent service level, another world-class major engineering equipment development task undertaken.
The use of 1 million kilowatt units at Baihetan Hydropower Station was not accomplished overnight, but a journey to realize the dream of Chinese hydropower generations bravely entering the world‘s hydropower “no man’s land”.
As early as the National Scientific Planning Conference held in 1958, Chinese industry experts submitted the “Preliminary Opinions on the Demonstration of the Capacity of Three Gorges Project Hydropower Units”, putting forward the concept of “Millions of Hydropower Units”, which opened the starting point for the dream-seeking process.
In 2007, the Harbin Electric Group submitted a feasibility study report for the “1000 MW Hydroelectric Generating Unit Research” project to the Ministry of Science and Technology. In the same year, relying on the National Science and Technology Support Program Project “1000 MW Hydroelectric Generating Unit Research”, it undertook 7 projects. National science and technology support project research work.
In 2011, at the Baihetan Feasibility Phase Installed Capacity Selection Review Meeting, the state approved the feasibility of 1000 MW units and confirmed that all Baihetan Hydropower Stations use 1000 MW hydropower units.
In this process, Harbin Electric Group has successfully verified a number of research results of the “Baihetan Million-kilowatt Hydropower Unit” on the Three Gorges, Xiluodu, and Xiangjiaba units. Harbin Electric Motor has fully developed the Baihetan Million-kilowatt Hydropower Unit. The capacity of the kilowatt unit.
