Zhejiang News Client Seeing Reporter Hu Jingyi Reporter Zhao Jing Correspondent Fu Yu Qing Chen Zeyun

What is the scene of the "contribution" of the sun and the moon?

Recently, the country's first tide complementary photovoltaic power station, the National Energy Group Longyuan Power Group, Zhejiang Wenling Chaoguang Supername Photovoltaic Power Power Station, which is the first time that my country has developed solar energy and tide. The spectacular scene allows people's attention to the major topics that can be used by the ocean again.

The vast ocean, the energy hidden in it is inestimable. However, compared to the shining photovoltaic and wind power in recent years, human beings have used the footsteps of the ocean to be slightly slow. Regardless of whether it is the country or the world, the ocean can use in the early stages of research and development. The high technical threshold, the large investment scale, and the long period of time are the main challenges.

In Zhejiang, thousands of islands, 6,500 kilometers of coastline, and 260,000 square kilometers vast waters provide a broad test space for the use of the ocean. Recently, the reporter from near the shore to the distant sea, visiting the three representative projects of tidal energy, trend, and wave energy to explore their revelation of further discovering blue kinetic energy.

Ingenious resources

Industrial heritage is rejuvenated

Wenling Jiangsha, a name of a geographical textbook of primary and secondary schools in my country.

In May 1980, as the first two -way tidal energy power stations in my country, the first self -study, design, manufacturing, and installation of the Jiangsha Tide Test Power Station, the first unit was put into production and power generation. At that time, the installed capacity of the power station was 3,000 kilowatts, and the annual power generation was more than 10 million kilowatt -hours. It ranked first in the country and the third in the world. To commemorate it, it is also engraved on the bronze road inscriptions in the Millennium of Beijing.

The webmaster Wang Haoping is 51 years old. Since the school gate is stepped out, he has entered the power station.

At that time, the power station that mainly assumed scientific research tasks. Today, how can we exert greater value?

In September 2020, the proposal of the "double carbon" goal is undoubtedly an excellent opportunity. "We see the opportunity to rejuvenate the industrial heritage from it." Said Zhang Junhao, director of the Ministry of Engineering Construction of Zhejiang Company, Longyuan Power Group of the National Energy Group.

Where do you start? Everyone focuses on the reservoir area of ​​the test power station. "The tidal power generation needs to be built by the seaside, and the internal and external water levels are formed by the ups and downs of the tide. Finally, the potential power is used." Zhang Junhao explained that the water surface of the Jiangsha tidal pilot power station can make a big article.

After several rounds of planning discussions, the company decided to invest about 400 million yuan in installing photovoltaic power generation components in the reservoir area to create a new model of tidal and photovoltaic coordination. In less than a year, the Jiangsha Tide Test Power Station has a huge complementary partner. Its total installed capacity reaches 100 MW. It is expected that during the 20 -year operating period, the average annual power generation hours can reach 1092 hours. Annual power generation exceeds 100 million kilowatt -hours, which is equivalent to meeting household electricity needs of about 30,000 households for one year. Compared with thermal power, about 31,654 tons of standard coal can be saved each year, and 84,479 tons of carbon dioxide emissions can be reduced.

The Jiangsha Tide Test Power Station and the "New Partner" constitute the first tide -and -complementary photovoltaic power plant in the country.

"We also develop and build a digital platform for production, establish a health warning model of landscape equipment, and use AI intelligent diagnosis and other technologies to realize the functions of drone one -click cruise, fault positioning, report analysis and other functions." "Intelligent heart", facing the area of ​​the size of 187 standard football fields, operations and maintenance personnel can quickly remote diagnosis with the help of digital intelligence tools to achieve young people on duty and no one.

In the power station, there is also a huge "charging treasure" -5 MW -time energy storage equipment. According to Zhang Jiangfeng, a network source coordination technician of the State Grid Zhejiang Academy of Electrical Sciences, due to the randomness of solar energy, the measuring merger merged may affect the stable and safe operation of the power grid. The "second -level" is promoted to the "millisecond", which can quickly and flatten power fluctuations, and realize that clean energy "should do both" and make full use.

Standing on Wenling Qiyitang, on the left is Dahai, Dam and Jiangsha Tide Test Power Station. On the water on the right reservoir area, more than 185,000 photovoltaic power generation components are paved to the front line of Haitian, and there are smart drones. Patrol over above, a new weather.

During the same period as the Jiangxia Tide Pilot Power Station, our province also developed a number of small tidal energy projects in the last century. The relevant person in charge of the Provincial Energy Bureau said that while continuing to increase the scientific research of tide, it can improve economic benefits and revitalize the old industrial heritage by developing a variety of energy and comprehensive use of land.

Located LHD Trending Power Station in Xiushan Island, Pushan County, confessed

Primitive innovation

Accelerate the upgrade of core equipment

Repeated world -class problems, the "Zhejiang standard" showed by the LHD trend power station located in Zhoushan, Zhoushan.

Since 2017, the LHD trend power station has continuously connected to the fifth anniversary of the grid -connected power generation, and the cumulative grid -connected power generation has exceeded 2.8 million kilowatt -hours. Monthly investing in grid -connected operation marks that my country's trend can develop technology level to a new level ...

With the support of the previous operation results, the LHD Trend Energy Power Station twice selected the "Global Ocean Energy Energy 20 Highlight Project" and "Global Trends Highlight Project" released by the International Energy Agency's Marine Energy System Technical Cooperation Program (IEAOES-TCP), which further improved The international attention of my country's marine energy. No one expected that Lin Dong, a well -known Wenzhou entrepreneur in "Green Sheng Beef Jerry", achieved achievements in the field of ocean energy.

"Primitive innovation is the most important. Our technical route is completely different from other trends in the world." Lin Dong said. "From 0 to 1", the project first applies the "platform plus turbine modular power generation principle" to the bottom of the sea, and the kinetic energy of the turbine transitions to promote turbine to power generation; "from 1 to 100", technology is continuously iterated. The three generations of units invested less than 1.5 times, the single -machine capacity increased by 5.3 times, and the power generation capacity increased by several times.

Lin Dong showed reporters to the first month of power generation data of the "Endeter Endex": 120,000 kilowatt -hours of network electricity on a single month, refreshing the record again! At present, the power generation project has obtained 63 patents authorized in international and domestic, but the pace of research and development will not stop there. Lin Dong's next goal is "upper scale and efficiency", which eventually allows the trend to be lower than thermal power.

There is not enough core technology innovation, and the upstream and downstream of the industrial chain must be innovative. Thousands of large -toned parts need to be used to find manufacturers in the three places of Hangzhou, Naga, and Zhou according to the drawings. "Two -thirds of the parts processed for the first time are failed products, and the project funds have made R & D tuition fees." Lin Dong said with a smile. It turns out that the reality of the sea floor has "accidents" that are difficult to estimate by computer simulation simulation. Salt and fog corrosion, sealing leakage, seabed garbage invasion ... All need to improve production according to the test data.

Until now, the current measuring instrument is still "blockbuster". The data of the current measuring instrument is related to the crew of the unit, and the currently developed measuring instrument developed by countries on the market can only be continuously used for not more than 10 months. We can only be replaced. "For this reason, we are also independent research and development of durable products." Lin Dong said.

Last year, the Zhejiang Provincial Development and Reform Commission and the Energy Bureau issued the "Fourteenth Five -Year Plan" of Zhejiang Province's Renewable Energy Development, which mentioned that during the 13th Five -Year Plan period, the province's trend can achieve major breakthroughs in research and development. The technology is generally close to the international advanced level. Essence A batch of installed capacity of the trend of ranging from 60 to 650 kilowatts completed the real sea condition test in the Zhoushan waters. The trend of universities and scientific research institutions can be constructed in Zhoushan and put into test operations in Zhoushan.

"At present, the development of technology development in our province is still in the stage of demonstration. We will continue to promote the development and demonstration application of the development and use of new technologies and new equipment to accelerate the upgrade of core equipment, and maintain the province's province's research and development and application of marine energy technology technology research and development and application. Leading. "The relevant person in charge of the Provincial Energy Bureau said.

"Jueku" new wave energy generator crew tested the respondents in the large wave pool to test the illustrations

Government -enterprise coexistence

Explore the road of marketization

Industrial development costs are very high, and large -scale application difficulties are very difficult. This is already a consensus in the field of maritime energy. But no matter how far the journey is, there must be a courage to climb the peak. The wave energy project located in Shengsi, Zhoushan has formulated a "roadmap".

At present, diesel is often used on remote islands that do not pass submarine cables. "The cost of 93%to 95%is at the raw material side, and the cost of electricity is above 3 yuan, and at the same time, it will generate air pollution." Han Yang Energy Technology Equipment (Nantong) Co., Ltd. executive director and general manager Han Lei introduced that if we can use waves, we can use waves to wave waves. It is undoubtedly an ideal solution to be able to generate electricity and set up an independent micro -grid for remote islands or maritime facilities. This is also the business application direction of Hanyang's energy aiming.

Recently, the third -generation "Jueku" new -type wave energy generator set in the Fisherman's Wharf of Wulong Township, Shengsi County has entered the sixth month of the real sea test. It is small and "no place". It can be generated in microwaves above 0.2 meters and has a wide range of application. The average efficiency is more than 15%higher than photovoltaic power generation. The cost, the cost of electricity has dropped to 0.44 yuan. "At present, there is no problem with small -scale installation, and commercial promotion only competes for the day and night." Han Lei was full of confidence.

In his "roadmap", the two application paths gradually became clear. The first is the small -scale commercial installation. Relying on the docks, dykes, maritime oil and gas platforms, breeding fishing grounds and other buildings, single -generation generators are placed on the sale of electricity or equipment to customers. "For the island, compared with solar energy and wind energy, waves can have higher energy density and longer -year power generation time." Han Lei said that at present, the team is still developing from 10 generator crews. The MGA array expands the scale of power generation and improves economic benefits.

The second is to combine with offshore wind power to create a comprehensive development model. "The waters of the installation fan are generally difficult to connect. Putting waves of power generation units on the sea can improve the utilization rate of three -dimensional space and create higher per mu." Han Lei said. More importantly, through the sharing of submarine cables, transformers and other equipment, the transmission cost of wavy power generation power generation will be greatly reduced, which is the "cloth formation method" that complements each other. In this way, the generator crew will also be unbinded with near -shore buildings to open up a broader COSCO ship.

This "roadmap" coincides with the "Fourteenth Five -Year Plan" in Zhejiang Province. Actively explore the promotion and application of ocean energy supply and marine aquaculture power supply, and encourage comprehensive development test demonstrations of marine and sea wind power. "At present, the most lack of funds, partners and opportunities, especially comprehensive development, requires strong business partners." Han Lei hopes to be seen by more people in the context of the "double carbon" era. The good news is that this sea test has attracted the attention of many central enterprises and state -owned enterprises.

In addition to developing the market for users, Han Yang Energy is also looking for business opportunities between peers. Next, the team plans to cooperate with Shengsi County to jointly create a wave energy test base to attract more clean energy projects to settle in. "Real sea conditions testing is completely different from the laboratory simulation. Real problems such as marine life, seawater corrosion, typhoon weather, etc. will be considered." Han Lei said that the base can provide other companies with the test venue of the prototype. In the future, this business model Maybe it can help the ocean to develop the industrial cluster and the industrial chain.

Our province has engaged in green high -tech research on sea -related enterprises, and provincial industrial funds are given market -oriented support. The person in charge of the Provincial Energy Bureau said: "We will also guide enterprises to make good use of green financial policies to help the province's ocean can use the development of industries."

In addition, policy support is also an important part of business promotion. In August 2019, the Provincial Development and Reform Commission "customized" the first trend in my country for the LHD project. Until now, the LHD large marine trend energy research center is still collecting a check of 2.569 million yuan, which is the first electricity fee charged by the LHD project to Power Power Company of State Grid. "Although the income is not conspicuous compared to hundreds of millions of yuan in these years, this is the beginning of opening the commercial market." Lin Dong said.

What can the ocean be?

There are huge motivation resources in the ocean. As renewable clean energy, the development of the ocean is of great strategic significance for the use of marine resources, accelerating the transformation of energy structure, and responding to global climate change. In the context of our province's marine economic development and "double carbon" goals, ocean can become a hot spot for future new energy development.

The ocean can be diverse, mainly including tidal energy, trend energy, wave energy, temperature difference energy, salt difference, etc.

Let's take a look at tidal energy, trend energy, and wave energy:

Tidal energy

The potential energy of the tidal vertical direction, that is, poor water level, is similar to the Three Gorges Dam. After investigation, the tidal energy resources of Zhejiang and Fujian provinces accounted for about 81 % of the country.

Trend

The kinetic energy of the tidal horizontal direction, that is, the impact, the principle of power generation is similar to the wind power generation. Zhejiang is one of the most abundant regions of domestic trendy energy resources. In the seas of Zhoushan alone, the trend can develop and utilize more than half of the country, equivalent to 23 Qinshan nuclear power plants.

Wave energy

Captured the energy contained in wave shocks and swinging. In the coastal areas, waves can flow density of about 2 kilowatts per meter to 7 kilowatts. In a place with high density, the energy flow of waves outside the coastline of the coast is enough to provide lighting for 20 families, and the development potential is large.
