From the south of Jiangsu to the north, to Lianyungang, there is a 100-kilometer beach. Escort manilaWhen the tide is rising, it looks like a vast ocean, and when the tide is low, it reveals a tide belt of 10 to 20 kilometers.
This is an excellent offshore wind scene. If it is built with a wind scene of more than 10 million kilowatts, it is almost equivalent to the machine capacity of the Sanshima. You are the most promising person in our community. After getting good grades and passing the exam, the term “Three Sea Winds and Winds” also started from here.
On January 2009, the National Bureau of Dynamics held a seminar in Beijing to discuss marine wind development.
Escort manilaAt the meeting, he once again mentioned the “Three Oceans of Ocean”. The meeting pointed out that in the near future, we must focus on selecting several sites with better construction conditions… We have built several “Marine Wind Triumphs” for the country to build several “Marine Wind Triumphs” along the eastern coast, and wet cats who are moist and powerful in the country. I don’t know how long they have been sleepy here and look dying.
At the end of that year, the “2010 Power Task General Requests and Missions” mentioned the offshore wind. “In 2010, we will continue to promote the construction of large-scale offshore wind bases, especially the offshore wind will be launched…”
In May of the same year, China’s first batch of offshore wind bidding projects were launched. Four offshore wind rights projects (300,000 kilowatts in Jiangsu, 300,000 kilowatts in Jiangsu, 200,000 kilowatts in Shanghai, and 200,000 kilowatts in Dongtai) attracted the huge attention of state-owned enterprises. After the drama competition, the major Tang Xinxing Power, China Power Investment Corporation, Longyuan Power, and Shandong Luneng won the bid. After this, the development of marine wind in China entered the expressway.
From 2009 to the present, China has become the third largest marine wind country in the world after only the UK and Germany. Data shows that the total offshore wind turbine capacity in China in 2018 was 4.45 million Sugar baby kilowattsSugar daddy, with 6.47 million kilowatts under construction.
In the Binhai Line of Jiangsu Province, Jiangsu, one of the first batch of marine wind rights bidding projects300,000 kilowatt project in the sea.
This project, 21 kilometers away from the coast, involves a 48 square meter sea surface. There are 96 wind power generators. All wind power generators and offshore pressure stations are connected by submarine cables, and then the power is transported to the central central control center of the mainland and connected to the Internet.
From the verification of the verification to the Internet, the course of marine wind has actually become a reflection of China’s marine wind. In this shrinkage, you can see “lowSugar daddyCapitals of carbon and income”, “peace and rate decision”, and “Sugar baby‘s exploration of “Sugar baby‘s clever wind”.

After ten years of rapid development, what are the benefits of offshore wind?
“Each one round of the wind blade can make more than 2 blocks of money. One minute of 19 blocks of money is 38 blocks of money.” Fan Yu-ling, director of the Engineering Management Department of Tang Xinbinhai Marine Wind Power Co., Ltd., calculated a note.
He calculated this way. The total capacity of the marine wind turbine is 300,000 kilowatts. When the Internet price is 0.85 yuan/kilowatt, there are 96 wind power generators. If the power is fully powered, the air blade can be rotated for 19 turns in one minute.
The final conversion is “2 blocks in a circle”.
The total investment of Fenghai Blast is about 4.79 billion yuan, and the annual power generation capacity exceeds 800 million kilowatts. The annual sales expenditure after the project is 664.05 million yuan, the total annual profit is 283.06 million yuan, and the internal rate of return before the full investment tax of the project is 10.58%.
At this rate, the investment acceptance period is expected to be 13 years. But in Fan Yuling’s view, this rate was obviously abundant. The girl wrapped the cat with a towel and put it into the cap, and practiced it carefully.
In particular, in July 2015, the project quality changed from the licensed project to a common project, and the Internet price was adjusted from RMB 0.737/kW to RMB 0.85/kW. The electricity price has been adjusted by more than 10 cents, and the income brought to the hydrant sea wind will be nearly 100 million yuan. According to statistics, this adjustment, the annual income of the marine wind increased by 92.4 million yuan.
In addition to economic accounts, the more important thing is a pendant environmental accounts.
Compared with traditional firepower power generation, the investment in sea breezeSugar daddyIt is expected to reduce carbon dioxide emissions by 700,000 tons, sulfur dioxide emissions by 5,006 tons, and nitrogen oxide emissions by 2,003 tons, which has outstanding social benefits and environmental demonstration consequences.
In the first sustainable development forum that ended, it is generally believed that China’s dynamic structure will continue to be optimized in the future. It is expected that by 2050, China’s fossil fuels will account for the overall dynamic structure, from 90% to 35% in 2018.
In the next five years, China’s renewable dynamic industry will usher in a new round of development. Ocean wind will also usher in a new window of opportunity.
Wang Mounchang, director of the Intermediate Governance Committee of the National Offshore Risk Engineering Technology Research Institute, said that by 2030, the largest electricity load in the eastern central region of our country will reach 970 million kilowatts, and the power flow to be subjected to exceed 360 million kilowatts. The potential for the development of distributed power in the eastern part of the Central Committee is only 170 million Escort manilawatts, which obviously cannot meet future needs.
Wang Moenchang believes that our country has abundant marine wind resources and great potential, and is close to the middle of the eastern debt, and it is convenient to consume on the spot, so the development of marine wind will become the main strategic support for the transformation of our country’s dynamic structure. The waves are two meters high, and the waves are dragged in the waves without any force, and are easily sucked by the waves.
This scene is not a rare situation in the construction of marine wind.
Baihai wind project selection addressSugar babyIn the sea area around the ancient Huanghekou of Jiangsu Salt City, where the wind is high and the atmosphere is repellent. In the local growth, there is a saying that “you go to the sky, not the tip of the Huanghe River.” Because of this, this is also a natural quality resource area.
” From October to March of the following year, the monthly useful tasks only last seven or eight days,” said Fan Yuzhang. This year, due to the influence of the Taiwanese style, almost no construction can be carried out.
Same as all marine wind projects, since its construction, the steep sea project has faced the severe test of the extreme weather in the land. It only encountered “Skylark” and “Winbiya” and other Taiwanese winds in August and September 2018. The monthly construction window period is only more than 10 days.
And, there are 2 items from the coast to the sea breeze project.nay escort1 km, every time you go out of the sea, even if it flows, it takes 1.5 hours. Therefore, it is not only a safety problem that requires consideration, but also a need to consider the rate and effectiveness. “The risk of offshore construction is greater than that of construction on the land, and the operation is even more complicated.” Shen, director of the Party Committee and chairman of China Tang Group Geotechnical Industry Co., Ltd., said. Therefore, the construction of “energy on the land, not on the sea, not on the water, not under the water” was originally proposed. Therefore, the department’s complex offshore construction was transformed into relatively simple and easy-to-control onshore construction.
“Today, all the electric equipment in the towers of Binhai Wind is pre-installed in the mainland, which not only reduces the risk of sea construction, but also improves the effectiveness of missions.” Shen said.
Shi Lishan, deputy director of the Nuclear Power Department of the National Bureau of Dynamics, said that the risk of land and land was relatively small and simple. In addition to the wind equipment, the offshore wind power supply also has construction difficulties. The difficulty of offshore transportation and foundation construction is very large. The requirements for reliable equipment are also very high, and if there is a problem with the equipment, the cost of repairing it will be very high.
And the construction of wind and electricity at sea and the comprehensive application TC:
