Chapter 885 Clean Energy Corridor
Weng Yongqiang remembers very clearly that he followed Soviet experts to design the Sanmenxia Water Conservancy Project, climbed mountains and waded through water, overcame many difficulties, and finally completed the design, and then participated in the construction of the Sanmenxia Water Conservancy Project.
When he first participated in the design, he was only 17 years old. When the first unit of the Sanmenxia Hydropower Station was generating electricity, he was 36 years old when he left the Sanmenxia Hydropower Station.
Then he went to the southwest and participated in the design and construction of water conservancy projects in the southwest.
He has been working for 40 years.
China has also learned to design and build water conservancy projects from the Soviets to now being able to independently design and build large-scale water conservancy projects.
In the past 15 years, China has built a large number of water conservancy projects and produced a large number of achievements, leading the world.
China even went overseas to design and build reservoirs and hydropower stations.
Although he is about to turn 60, Weng Yongqiang is full of passion for work.
Yes, Weng Yongqiang believes that as long as the motherland needs him, he can still work healthily for 20 years and work until he is 80 years old.
Liu Tao smiled and did not do much.
If you ask these old people to rest, they will definitely not want to rest. They will feel uncomfortable and will soon develop various problems.
Liu Tao and Weng Yongqiang walked towards the dam. Like Xiangjiaba, a first-level vertical ship lift is set up on the left bank, with a maximum lifting height of 114.2 meters. It can pass a 2*500-ton one-top two-barge fleet or a 1,000-ton one-top one-barge fleet. It only takes 15 minutes for a thousand-ton ship to pass the dam, which is much faster than the average 5-hour dam passing time of the Three Gorges ship lock.
Of course, this does not mean that the ship passing design capacity of the four major hydropower stations on the Jinsha River is more advanced than the Three Gorges ship lock, but because the two have different ship navigation. The planned and designed navigation capacity of the Jinsha River is 1,000-ton ships, while the Three Gorges is different. The planned and designed navigation capacity of the Three Gorges Dam is 10,000-ton ships.
The next day, Liu Tao left the Xiluodu Hydropower Station and came to the Baihetan Hydropower Station.
Now the first batch of units of the Baihetan Hydropower Station has not yet started to generate electricity. It is expected to take about three or four months before the first batch of units can generate electricity.
Baihetan Hydropower Station is located in Ningnan County, Sichuan Province and Qiaojia County, Yunnan Province. The normal water level of the reservoir is 825 meters, with a corresponding storage capacity of 20.6 billion cubic meters. The underground plant is equipped with 16 units with an installed capacity of 16 million kilowatts and an average annual power generation of 60.24 billion kilowatt-hours.
After the completion of the Baihetan Hydropower Station, 22,000 mu of cultivated land and 102,000 mu of forest land will be submerged, and tens of thousands of people will be relocated.
The entire Baihetan Hydropower Station rises from the ground and is built on the mountain. The steep mountain canyon is shrouded in clouds and mist. The seven cable cranes standing quietly on both sides of the mountain are like seven fairies descending to the earth. These are seven 30-ton cable cranes, which are specially used for the lifting of concrete materials for the dam of the Baihetan Hydropower Station.
The chief engineer of Baihetan Hydropower Station is Sun Dahong, who is 65 years old this year. Sun Dahong is also an academician of the Chinese Academy of Engineering. In 1958, the country planned to build a super-large hydropower station in Baihetan, and Czechoslovak experts provided technical assistance. At that time, Sun Dahong was the backbone of the technical force.
Unfortunately, the two sides parted ways in 1961, the preliminary work of Baihetan Hydropower Station was stopped, and the survey team withdrew.
Sun Dahong participated in all the work of Baihetan and was transferred to the Ministry of Water Resources and Electric Power in the 1970s.
Panshan Group started the four major hydropower stations on the Jinsha River and found Sun Dahong. Sun Dahong resolutely chose to accept the position of chief designer of Baihetan Hydropower Station, set up a survey and design team, and finally completed the survey and design work of Baihetan Hydropower Station, and was appointed as the chief engineer of Baihetan Hydropower Station.
It was because Sun Dahong made outstanding contributions in theory and engineering at Baihetan Hydropower Station and Three Gorges Hydropower Station that Liu Tao recommended Sun Dahong as an academician of the Chinese Academy of Engineering.
Similarly, this year he also recommended Ye Xianggao and Weng Yongqiang as academicians of the Chinese Academy of Engineering. These people are all talented and knowledgeable.
After inspecting the Baihetan Hydropower Station, Liu Tao took a helicopter to the Wudongde Hydropower Station. The total installed capacity of the Wudongde Hydropower Station is 10.2 million kilowatts, and 12 hydro-turbine generators with a single unit capacity of 850,000 kilowatts are installed.
On the dam, the clouds cleared and the rain stopped, and the warm winter sun sprinkled a dazzling golden color. The maximum height of the dam here reached 270 meters. It is a hyperbolic arch dam and also a super-high arch dam.
The dam is the core main building of the hydropower station. During the pouring of the dam concrete, the heat released by cement hydration will form a relatively high temperature inside the dam body. If the temperature is not well controlled, cracks will occur in the concrete structure, thus affecting the safe operation of the dam.
In order to solve the problem of temperature cracks in the dam, the Wudongde Hydropower Station uses low-heat cement concrete throughout the dam, and no temperature cracks have appeared since its construction.
The entire construction of the Wudongde Hydropower Station has set eight world first records, which is absolutely remarkable.
When all the units of Wudongde Hydropower Station are put into operation, the power generation of just one day can meet the living electricity demand of 300,000 people for a whole year.
Just half a month ago, the first unit of Wudongde was officially put into operation.
The chief engineer of Wudongde Hydropower Station is Liu Ming, the first graduate of Tsinghua University after the resumption of the college entrance examination. He was assigned to Kunming Survey and Design Institute and quickly stood out. After joining the work, Liu Ming also studied for a master's degree in water conservancy and hydropower. In 1984, he served as the leader of the dam design team and in 1989, he served as the deputy chief engineer. After the original chief engineer had problems, Liu Ming took over the burden of deputy chief engineer. Liu Ming is only 35 years old this year, which can be said to be young and promising.
The four major hydropower stations on the Jinsha River, the Three Gorges Dam, and the Gezhouba Dam in the upper reaches of the Yangtze River will form the world's largest clean energy corridor.
In two or three years, the four major hydropower stations on the Jinsha River will be able to generate 180-200 billion kWh of electricity per year, and almost all of this electricity will be supplied to the East China region. In addition, the Three Gorges Dam will generate 80-100 billion kWh of electricity per year after completion, and the Gezhouba Dam will generate 14.1-15.7 billion kWh of electricity per year, which will total about 300 billion kWh per year, thus solving the current power supply dilemma in the East China region.
During the previous negotiations, the provinces of South China and East China had to agree. One very important reason was that the development of these places relied on the large amount of power transmission from the southwest, and the provision of steel and other production materials from other places, as well as a large amount of manpower and markets.
China's development has always been a national chess game, which is destined to focus on the whole country, not just the development of one place.
Liu Ming took Liu Tao to visit the dam and the office.
There are many computers in the office. Although the four major hydropower stations on the Jinsha River were designed relatively early, they were all connected to the Internet. The operation is highly automated, and all kinds of monitoring instruments and equipment can be viewed on the computer.
In order to develop this set of software, ten universities including Southwest Associated University, Tsinghua University, and Beijing University worked with the Computer Research Center and Software Research Center of Panshan Group to develop it in more than a year.
In addition, there are independent servers here, mainly local area networks, and a few are connected to the outside Internet.
In terms of telephones, in addition to landlines, mobile phones, and intercoms, satellite phones are also equipped. This is to prevent special situations. For example, if the network cable is cut or the telephone line is cut, you can also contact the upper level through the satellite phone, feedback the situation to the upper level, and ask for help from the upper level.
