00:00:21155 is the opening year. China's economy
00:00:24is in a dynamic state
00:00:25.
00:00:30Three new things, rising strongly. Consumption
00:00:33is upgrading, with a vibrant atmosphere. Major
00:00:37projects are bringing new development prospects.
00:00:40Reporters are on the front lines, opening
00:00:44up new forces.
00:00:46.
00:00:48Luzhou Laojiao Guojiao 1573 reminds you to watch
00:00:52.
00:01:00The history you can taste ,

00:01:10. Let the facts speak for themselves
00:01:12.
00:01:15Focus Interview .
00:01:19Hello, viewers and friends, welcome to Focus Interview. Today we continue
00:01:23to watch the series "New Forces at the Beginning of the Year".
00:01:2615:17, our country's overall investment and soft construction.
00:01:37To promote the implementation of major national strategies and the construction of safe capacity projects in key areas, a total of 109 major projects have been deployed. This April, the Central Political Bureau meeting again proposed to accelerate the construction of water
00:01:41networks, new power grids, computing networks
00:01:44, new-generation communication networks, urban underground pipe networks, and logistics networks, totaling six
00:01:48networks. The opening year has passed halfway. How is the construction
00:01:52progress of these projects, and how will they change our lives
00:01:56? Let's go to the Yangtze River to take a look.
00:02:00The reporter came to the Three Gorges of the Yangtze River, this palace area. This is less than two
00:02:04kilometers from the Three Gorges Dam. It is the area where the construction of the new Three Gorges
00:02:08channel first began. Now this piece of land may not yet show any
00:02:12signs related to water, but in 10 years, a
00:02:16channel about 6.6 kilometers long will be built here. It will have a five-level
00:02:19ship lock, with a single ship up to 280 meters long and 40 meters wide, which is equivalent to
00:02:23the area of two standard football fields, with a minimum draught of 8 meters
00:02:27. Ten-thousand-ton giant ships will no longer be affected. From the logistics
00:02:31itself, it can save the entire society nearly
00:02:3416 billion in costs each year. He said that the circulation of the Yangtze River economic
00:02:38belt, the adjustment of major industrial layout along the river
00:02:42, this impact is more far-reaching. In the early stages of the Three Gorges
00:02:46project construction, the Three Gorges dual-line ship lock was designed with a throughput capacity of 100
00:02:50million tons. It is expected to reach that by 2030. What
00:02:53was unexpected was that in 2011 , the cargo throughput of the Three Gorges ship lock
00:02:57exceeded 100 million tons, 19 years ahead of schedule.
00:03:31In June this year, the project officially began. More than a month later, the reporter followed the person in charge of the
00:03:35project management department and felt the heat of construction in the preliminary excavation
00:03:38area.
00:03:46The entire excavation volume is more than 8.5 million cubic meters
00:03:49, which accounts for approximately one-twentieth of the total excavation
00:03:52volume of our entire Three Gorges New Channel project. Our preliminary excavation
00:03:56area serves as a pilot field, and it is for me.
00:04:42From a distance, although the blasting volume is not small, the earth and rock turned into
00:04:45crushed stones after the blasting, and there was not much displacement. Vehicles outside the
00:04:49blasting isolation zone were still operating normally. From the current inspection
00:04:53results, our method is effective. What we are doing now has a negligible
00:04:57impact on the Three Gorges Dam. Blasting operation, the excavated soil and rock will also be separated from the green earthwork and rock
00:06:42At the same time, we also have an environment for the habitat of our sturgeon. When we
00:06:46build new dual-line locks , we choose an outlet
00:06:49that has the least impact on the ecology and simultaneously ensures the safest
00:06:53passage. In addition to earthworks , the reporter saw that at present, at the Three Gorges Water
00:06:57Transport New Channel construction site, the relocation of these 500 kV ultra-high voltage transmission
00:07:00lines is also in full swing. These
00:07:04lines have been sending the power generated by the Three Gorges Dam
00:07:08to various parts of the country, but the old lines will affect new ships.
00:07:46China is using
00:07:49its own way to realize modernization.
00:08:13In April this year, the Central Political Bureau meeting proposed to accelerate the construction of
00:08:16water networks, new power grids, computing networks, new-generation communication networks,
00:08:20urban underground pipe networks, and logistics networks, totaling six networks.
00:08:24Among them, the new power grid is the core platform and important carrier
00:08:27for our country to build a new power system and new energy
00:08:31system during the 15th Five-Year Plan. It will be based on the main power grid and distribution network, supplemented
00:08:35by smart microgrids, to form a power grid system with coordinated operation of main,
00:08:39distribution, and micro. The new power grid's most basic aspect is this.
00:09:13This is the Yuezhou Converter Station at the junction of Ningbo and Shaoxing, Zhejiang.
00:09:17It is the terminal of the Gan-Zhe Ultra-High Voltage DC Transmission Project. So, the big guy
00:09:21being installed behind me is the heart of this converter station
00:09:25, the world's largest flexible DC converter transformer. After
00:09:29its conversion, the high voltage of up to 800 kV
00:09:33from the west will enter the power grid of Zhejiang Province, allowing the residents
00:09:37and enterprises here to also use the electricity from the west
00:09:40. We transmit through 800 kV.
00:09:42After arriving at Yuezhou, Zhejiang, it is converted and stepped down at this Yuezhou
00:09:46converter station, and then enters
00:09:49thousands of households .
00:09:53It can transmit 36 billion kilowatt-hours of electricity
00:09:57to Zhejiang every year, of which more than half
00:10:01, over 20 billion, is from new energy sources such as wind
00:10:04and solar. During the 15th Five-Year Plan, ultra-high voltage transmission lines
00:10:08running east-west and north-south will form the backbone of the new power grid. At
00:10:11the same time,
00:10:25At the end of July, in the Ningbo Qianwan New Area , the reporter saw workers completing
00:10:28the final framing work on the roof of a newly completed
00:10:32car park
00:10:33.
00:10:39The roof of the 19th floor of the enterprise where I am currently located is completely covered
00:10:43with photovoltaic panels. On such a sunny day, it can generate over 60,000
00:10:47kilowatt-hours of electricity. When production is busy, this electricity can be used by the enterprise itself. During
00:10:51holidays, this electricity can be fed back into the city's power grid. This
00:11:25originally meant that the city's distribution network, which was responsible for the last mile of power delivery, turned
00:11:29into a two-way power transmission line, which also brought new pressure
00:11:32to the city's power grid. How can we effectively absorb distributed photovoltaic power
00:11:36without causing too much trouble to the power grid ? During the interview, the reporter saw
00:11:40a planning simulation platform, specifically for providing optimal planning
00:11:44suggestions for distributed photovoltaic access to the city power grid. We have
00:11:48this new photovoltaic access. If we only need to select
00:11:52the access location corresponding to this platform,
00:12:35But at the same time, Ningbo is located on the southeast coast, with frequent thunderstorms
00:12:39in summer. When a dark cloud floats over, what should be done
00:12:42? On July 19th this year, just after 11 a.m., many
00:12:46places in Ningbo were covered with dark clouds and thunderstorms began. The power output of the photovoltaic
00:12:50that was originally generating full power dropped sharply. That day, our curve was like
00:12:54this.
00:13:56For every enterprise and family , the greatest expectation for power
00:14:00supply is that it can be more stable, and even in unexpected situations
00:14:04, power should not be cut off 15:57 How to make our power
00:14:07grid more resilient? The reporter visited the last station in Ningbo, the backend
00:14:11brain of the power grid automation system
00:14:14.
00:14:17Zhang Jiming is a power grid automation technology expert. When the reporter met him, he
00:14:20was checking with his colleagues the two typhoons that passed through Ningbo
00:14:24in July this year.
