The dam is towering, the river is flat, and the water is flowing east.

At the peak period of high temperature and heat, when the reporter came to the Baihetan Hydropower Station in the lower reaches of the Jinsha River, it coincided with the production and installation capacity of 10 million kilowatts here. Huadong Region.

"On August 2nd, the No. 7 water wheel unit of the left -shore machine room was successfully put into production and power generation. At this point, 10 million kilowatt water rotor generator sets independently developed by my country on both sides of Sichuan and Yunnan have been launched in 10 units." China Three Gorges Group Baihetan Project Construction Kang Yonglin, deputy director of the department, told reporters.

In the underground plant on the left side of the dam, 8 million units with a height of more than 50 meters and more than 8,000 tons are arranged in order. These behemoths are incredible and stable. The reporter erected a few coins in front of Unit 7, and the average tattoo remained motionless. Kang Yonglin introduced that the turntable of a single unit turns about two times per second, and can be generated about 150 degrees for each turn, which is equivalent to one month's electricity consumption.

The total installed capacity of the Baihetan Hydropower Station is 16 million kilowatts, and the average current power generation can reach 62.443 billion kWh. In 2017, the main project was constructed. Following the first batch of two units on June 28 last year, the builders fought continuously and strived to put into operation at the end of this year.

How to transport such a large power to East China Electric Power Load Center? The reporter explored the steep rivers of the Jinsha River bank to the higher altitude.

Along the way, the tower stood in the mountains, and the silver line flying was on Daling. The AC power from the Baihetan Hydropower Station enters the cloth and exchange stations along this 500 -kilovolt ultra -high voltage transmission line, and then transforms into a DC electricity, and then "transfer" ± 800 kV high -voltage transmission lines to East China.

"500 kV ultra -high -voltage lines are like national roads, connecting important hubs, and the traffic capacity is relatively small, suitable for travel in the province. The best choice for Yuanmen '. "Huo Guoqiang, executive deputy commander of the State Grid Sichuan Sichuan Electric Power UHV Engineering Construction Command.

The Budai Streaming Station is located on a hillside in Buhuoshan County, Liangshan Prefecture surrounded by mountains. It covers an area of ​​930 acres and about 90 standard football fields. The length of the underground cable of the two phases of the project reaches 2500 kilometers, and the more than 80,000 core cables form the "nervous system" of streaming stations.

The steel frame of the exchange field is lined. The changing factory building is not dyed, the fan is densely set, the DC field tube is circled by the network. The sweaty workers "pulled back" the reporter to the reality of the peak of the country's "one game".

Lei Longfei, the head of the State Grid Sichuan Electric Power DC Center Buchang Stream Station, introduced that the station was two ± 800 kV stream stations and a one of the Baihetan -Jiangsu (Baijiang Line) and Baihetan -Zhejiang (White Zhejiang Line) The 500 kV transformation station "three stations and one" are constructed. After intense construction, the Baijiang Line replacement station has been put into operation on July 1 this year. It only takes 7 milliseconds, and the clean power can "flash" Jiangnan from Shushui.

There is also a high -voltage transmission line that spans more than 2,000 kilometers synchronously with the streaming station. In mid -October last year, the construction of the tension field of the Baijiang Line Zhaojue section entered the stage of the transmission line, and the unmanned area along the way had already entered winter. At that time, in order to ensure the progress of the project, the 80 construction team members of the State Grid Sichuan Electric Power Sending Electricity Construction Co., Ltd. lived on the mountain with tents nearby, waiting for the weather to turn clear, and see the construction of the joints.

The construction team members lived on the mountain for nearly 30 days, and the team leader Pu Taiping stayed for a longer time -in the early spring, he went up the mountain in the early spring, and stayed in the mountains until the winter season.

Struggle to make fruits. The 500 kV supporting project of Baihe Beach was completed in 9 months and completed in 9 months. It started in July 2021 and was partially put into operation at the end of this year, and was completed by June 2023.

"By then, Sichuan will convey more than 150 billion kilowatt -hours of electricity to the Yangtze River Delta region each year, reducing carbon emissions by about 140 million tons." Hu Guoqiang said.
