【Core Reading】

Under the blessing of the "double carbon" target, the wind power industry has set sail.

On June 21 this year, in accordance with the Hunan Provincial Development and Reform Commission's approval of the "Resumption of the Development and Construction of the Fourteenth Five -Year Wind Power Project in the" Fourteenth Five -Year "of the province", the city will build 13 wind power projects during the "14th Five -Year Plan" period, and the installation scale will be built. 680,400 kilowatts, an estimated investment estimate of more than 5 billion yuan. Coupled with the 6 major wind farms in our city, Zhuzhou Wind Power's "team" is growing.

Banjin, who is "manufacturing famous cities", is how to re -position the wind power industry under the "double carbon" goal? In the construction of a new power system with new energy as the main body, what role will wind energy play?

A "wind" is blowing into millions of households

On July 11th, it was during the peak of the electric electricity in midsummer. In the Mingyue Mountain Wind Farm in Liling City, a tall and spectacular windmill stood on the peak of Lian Mian Mountain. Green wind power is delivered to millions of households through the grid here.

Mingyue Mountain Wind Electric Farm in Liling City.

"The first wind farm project of Fuling City, the three towns of the three towns of the three towns of the mountain, Jun Chu, and Chashan, has been grid -connected for half a year. At present, the current power generation has reached 34.42 million kilowatt -hours to power the city in Lingling and Zhuzhou City." The person in charge Feng Wei told reporters.

Above the mountains, the windmills are not only one of the one.

In recent years, there have been 6 windfield grid -connected grid -connected power generation in our city. Each county has at least one wind power project, including the Mingyue Mountain Wind Electric Farm in Liling City, Fenghuangshan Wind Electric Farm, Longfeng Longting Wind Electric Farm, Youxian County Taihe Xianfeng Electric Farm, Chaling County Sanxiangfeng Electric Farm, Yanling County Jinzi Xianfeng Electric Farm.

"The total number of power generation in the 6th wind farm is about 600 million kilowatt -hours." The relevant person in charge of Datang Huasin Zhuzhou Power Generation Co., Ltd. said, "According to the city's regulation of 11.7 billion kWh of power supply in 2021, Zhuzhou Fengneng power generation accounted for the whole society for the whole society. The proportion of electricity is about 5%, and the contribution of wind power to the city's power supply will continue to increase. "

Behind 5%is a reconstruction of new power systems with new energy as the main body.

Like many industrial cities, there are many industrial enterprises in Zhuzhou, the economic structure is "heavy", the demand for electricity consumption is large, and the energy resources consumption is large. It has always relied on traditional coal power generation. It is a key area for electricity load in Hunan Province.

"In recent years, coal prices have been high, and traditional coal power generation operating costs have been high due to increased fuel costs. Its operating costs are already six or seven times of wind power operation costs." introduce.

Taking the Phoenix Mountain Wind Electric Farm in Qiaokou District as an example, the wind farm has a year -on -year power generation of approximately 167 million kilowatt -hours, and the cumulative historical cumulative power generation is about 417 million kilowatt -hours, which is equivalent to saving 141,800 tons of standard coal and 358,600 tons of carbon dioxide emissions.

In Long Weizhi, wind power is not only zero -carbon power, but with technological progress, wind power is also becoming the most economical energy, and it plays an increasingly important basic support role in local economic and social transformation and development. On the way to cultivate famous cities and build happy Zhuzhou, wind power, as an important renewable energy source, is an important starting point for Zhuzhou's energy structure to transform and achieve the "double carbon" goal.

A "chain" is dancing with "wind"

Transformation "Multi -Energy Completion Integrated Energy Supplier"

With the "double carbon" flag, Zhuzhou has already heard the "wind" and moved.

Zhuzhou's maximum thermal power plant -Datang Huasin Zhuzhou Power Generation Co., Ltd. is good, and it is transformed from traditional thermal power companies to wind, light, and fire "more energy supplier".

In fact, it is not surprising that thermal power companies have made great efforts to generate new energy power generation projects. On the one hand, in recent years, due to high coal prices, electric enterprises have been in trouble due to high costs; on the other hand, under the goal of "dual carbon", the energy supply structure has been adjusted, and the proportion of wind power and photovoltaic power generation is the general trend.

In the context of "dual carbon", the most obvious feature of energy structure transformation is the decrease in the proportion of thermal power and the increase in the proportion of new energy. Therefore, traditional energy companies actively transform and lay out new energy tracks to cope with the shrinking traditional energy market after the carbon peak.

"In addition to the traditional coal power generation, in the past two years, we have expanded to new energy power generation fields such as photovoltaics and wind power. With the advantages of the wind power manufacturing of Zhuzhou, it provides a one -stop service for the construction and operation of wind power projects." Long Wei Wisdom.

In December last year, 11 typhoon power fields of Mingyue Mountain Wind Electric, Fuling City, built and operated by Datang Huasin Zhuzhou Power Generation Co., Ltd. have been connected to power generation. At the end of July this year, the other 9 typhoon will also generate grid to power generation. At that time, the wind farm will be The power generation can reach 80 million kilowatt -hours.

The construction site of Mingyue Mountain Wind Electric Farm in Liling City.

Not only that, with the "holding hands" with CRRC Zhuzhou, with the advantages of the manufacturing of Zhuzhoufeng electricity, Datang Huasin Zhuzhou Power Generation Co., Ltd. is moving towards the province to carry out business. At present, a wind farm in Hengyang, which is responsible for the construction and operation of Datang Huayin, is being built, which has also become the first new energy wind power project that the company has been connected since the transformation.

Long Weizhi said that in the context of the "carbon peak and carbon neutralization" strategy, my country is clearly building a new type of power system with new energy as the main body. The potential is imperative.

The annual revenue of Tower Tower is 800 million yuan

As an important support for the wind turbine, the "strong" level of the wind power tower determines whether the wind turbine can operate well. The Hunan Ledes Metal Structure Co., Ltd. (hereinafter referred to as Ledes Metal), which is quietly located in the Dongjiayu Gaoke Park in Lujing District, is an important enterprise in the tower of the tower of the tower of the wind power industry chain in our city. The company's operating income reached 800 million yuan last year.

Led Metal is a wholly -owned subsidiary of China Energy Construction Group Hunan thermal Power Construction Co., Ltd. Since 2009, the wind direction of the new energy market is keenly captured, and Lid Metals have officially entered the wind power tower industry and entered the Dongjiayu Gaoke Garden in 2014.

From the original steel structure industry to enter the wind power tower industry, Ledes metal used a strong quality system to open the market. In recent years, the company has actively connects with international standards and has passed the quality certification, safety and environmental management system certification, and EU steel structure welding system certification, which has enabled product quality to be based on stable controlling quality activities.

Chenzhou Yangtian Lake Wind Electric Farm, Chongqing Shizhu Maple Wind Electric Farm, Xilin Guoli League Aqi 225MW wind farm, Zhanjiang Xuwen 600MW sea wind field ... from the province to the province, from the inland to the sea, now there are more than 80 nationwide in the country, In the wind farm under construction or put into production, a fan tower tower of Lid metal was used.

Lidy Metal Corporation Fan Tower Production Workshop.

"According to the installed capacity and demand of the wind farm, the lightest weight of the tower is also 290 tons. We have done the heaviest project so far to match the 13MW wind power unit model, and the tower weight reaches 800 tons." Li Li. Zhang Jin, deputy general manager of German Metal Corporation, introduced.

To this end, Led Metal has also begun to deploy the industry in the country. At present, the company is located in the northern branch of Songyuan City, Jilin Province. It has 2 tower cylindrical production lines. At present, the monthly output is about 20 sets of land wind power tower. The annual output of the tower is 70,000 tons. The branch has two tower production lines. It can produce more than 15 sets of sea wind power tower per month, and the annual output of the tower is 80,000 tons. At the same time, the factory area is also equipped with a freight terminal, dock and port pool, which can stop 10,000 tons of ships.

"Last year, the company's only wind power tower business, the annual operating income reached 800 million yuan, accounting for nearly 80 % of the company's total camp." Zhang Jin said that this year, the company also has 400 million yuan in orders, and the company has also been in hand. All will be delivered within the year.

The second in the country with wind power blades

In March of this year, the TMT185 blades produced by the Time New Materials and produced by the Monxi Branch were officially offline. The length of the leaves was 91 meters. It was the longest on -site wind power blades that had been offline at that time. This also marks that the new materials of the times have gone at the front end of the industry in terms of design capabilities and manufacturing capabilities.

Wind power blades are key components where wind power units convert wind energy into mechanical energy, accounting for about 15%to 20%of the cost of wind power, second only to the tower. The thin shell structure.

As a leading enterprise in the field of wind power, the wind power blades business of the new material has developed rapidly in recent years. Focusing on the development trend of "large -scale, lightweight" of wind power leaves, the company continues to adjust the product structure, focusing on large leaf types such as 146, and carried out a series of product innovation.

For example, the first TMT72.5 maritime blades have been developed, with a new structure and lightning protection system; jointly developed 161B carbon fiber tensor squeezed blades and the earliest domestic 3.xmW "70 meters+" leaves, which uses high -profile fiber to solve the super The technical difficulties of the long blades improve the rigidity; the development of domestic PET materials has established the evaluation capabilities of the leaves and components, which has passed third -party authoritative certifications; the first to develop and produce the production and production of sea and land use wind power generation blades, and so on.

According to the "2020 Global Leaf Supply Chain Report" released by GWEC (Global Wind Energy Council) in 2021, the production capacity of the new materials has reached 10000MW/year, and the supply chain has 6. Second, the top three in the world.

Since the beginning of this year, the new materials have maintained the growth of the wind power business. In the first quarter, the revenue of wind power blades was 1.388 billion yuan, an increase of 7.8%year -on -year, accounting for 36.51%of the total operating income.

Public information shows that in the future, in terms of technology, the new materials of the times will still be based on the low wind speed and the Da Muwa -class blade market, keeping up with the development of the "Sanbei" and "Shuanghai", and fully realize the internationalization of wind power leaves. For low wind speed areas in the central and central and southern parts, the development of leaves with 4MW and above levels, including further lightweight cost reduction; for the three north regions, focus Overseas leave export research and development team.

Considering the competitive landscape at home and abroad, the new materials of the times are also actively seeking new increases, supporting local supporting facilities through domestic and foreign base construction. At present, the company plans to raise funds of RMB 73.16 million to invest in a wholly -owned subsidiary in Songyuan City, Jilin Province. Business, it is planned to build 4 new 5MW and above wind power blades production lines. After the project is reached, 240 sets of leaf capacity will be formed. "Overseas will give priority to building production bases in Southern Asian countries and regions such as Vietnam." Said Li Zhi, deputy general manager of Times New Materials Electricity Products Division.

A "net" will stand on the "wind" port

The future prospects of competition with the coal power market are expected. In the construction of new power systems with new energy as the main body, how should Zhuzhou "move forward"?

"New energy such as wind power, photovoltaic and other new energy to a certain extent 'rely on the sky to eat', which has the characteristics of volatility and intermittentity. In the future, large -scale and high -proportion access, how to ensure the stable supply of power and achieve high -level consumption utilization, which is more concerned about the industry. Question. "Wang Yixu, head of the new energy department of Datang Huasin Zhuzhou Power Generation Co., Ltd.

In his opinion, the current wind power resources of Zhuzhou are mainly concentrated in the southern region, and the local wind energy resources are more abundant. To make full use of wind power, we must strengthen the construction of power infrastructure.

Zhuzhou is one of the high load centers in the province, with a large demand for electricity and a concentrated load area. This is both the current situation of Zhuzhou and providing development space for the future. "Once the entire wind power construction, power generation, and power consumption network, Zhuzhou's power energy structure will be quickly optimized to form a virtuous circle."

In recent years, the rapid development of the wind power industry has become one of the main models. This is largely due to the government's encouragement and support of the government, such as the protection of Internet electricity prices, compulsory grid, electricity price subsidies, and various tax preferential policies.

"To truly develop decentralized wind power, it is necessary to solve practical problems such as complex approval procedures, unclear power grid access requirements, difficult financing, and difficulty in land acquisition." He said.

With the development of the "Qianxiang and Wancun Yafeng Plan", the development of decentralized wind power will open the growth space of wind power, and the potential market space of decentralized wind power reaches 1000GW, and the domestic wind power industry will significantly benefit.

Fan "replace" on the agenda

Recently, Hualian Changwu, which is located in Liaoning Province, has completed the first hanging project such as "upper big pressure". The 58 850kW old units of the project will be replaced with 12 WT4000/D160/H100 4MW units provided by CRRC Zhuzhou. This is also the first "upper large -voltage" wind power item.

"The upper big voltage" is simply a large generator set and shut down small generator sets. The main purpose is to reduce energy consumption, reduce pollution emissions, and reduce backward production capacity.

At present, my country's wind power capacity has reached 328 million kilowatts, and the number of service crews exceeds 155,000 units. The post -market business with operation and maintenance techniques, performance upgrades, and retirement recovery has risen rapidly, becoming the "14th Five -Year Plan" or even "ten ten" and "ten ten". During the May and Five -Year Plan period, one of the topics of high -quality development of my country's wind power attracted attention from the industry.

In March 2021, the National Energy Administration proposed the "Notice on Realization of Wind and Photovoltaic Power Generation Development and Construction in 2021", and proposed to start the technical reform and upgrading of old wind power projects, and encourage owners' units to use technical reforms and replacement methods. , Focus on the technical reform and upgrading of wind turbines with a single machine capacity of less than 1.5MW. At the same time, the wind farm, which has been operating for more than 15 years to carry out transformation, upgrading and retirement, and clarified the specific plan for the reconstruction and upgrading project subsidy.

The 850KW wind power unit installed in the two wind farms of Huadian Changwu and Kangping was put into operation in 2006. It has been operated for 16 years. The cost of equipment maintenance has increased year by year, and the usage of fan usage continues to decline. In this context, Liaoning Huadian New Energy Co., Ltd. has begun to vigorously promote the active strategy of the development of new energy projects, fully research policy requirements, optimize existing wind farm resources, and put forward the ideas such as old wind turbines.

Following the pulse of the times, relying on the deep foundation of China CRRC and Huadian Group's strategic partners and the advantages of the technical solution of CRRC Zhuzhou, the two parties quickly completed the technical agreement negotiations and determined the delivery plan.

It is reported that after the transformation and upgrading, all new units are expected to be connected by about 150 million kilowatt -hours after grid grid, and the number of hours of utilization reaches 3200 hours. The successful implementation of the project not only solves the problem of power generation efficiency and economic income of the project itself, but also responds to the policy, regional regional, regional adjustment of power structure, promoting sustainable development of wind power, and the construction of similar projects in the country. Provide a comprehensive reference basis and practical experience.

In addition, the coordinated Qingshan Green Water (Tianjin) Company of CITIC Zhuzhou also conducted innovative exploration in a series of matters such as environmental protection, resident influence, foundation recovery, and solid waste disposal during the demolition of the project, for the follow -up After the large -scale retirement of the wind farm, the green demolition and disposal have accumulated valuable experience.

Since 2021, the transformation of the "upper big pressure" wind farm is setting off a climax. Studies have shown that during the "Fourteenth Five -Year Plan" period, the size of the old wind farms with a length of more than 20 years in domestic operations is about 900mW, and the size of the old wind farm with a length of more than 15 years will exceed 30,000 mW. Great potential.

For wind power companies, this will be a new market opportunity. In the field of deep cultivation in the field of wind power for 16 years, China Che Zhuzhou currently has more than 1,000 operating and maintenance engineers, more than 200 wind farms, and more than 9,300 typhoons. The goal of the leader is moving forward, comprehensively deploying intelligent diagnosis, technical upgrades, inspection and testing, component maintenance, spare parts sales, wind farm unit upgrade, training consulting and other business areas of the wind and power generation equipment Lead the development of clean energy services, and the wise drives green sustainable future. The operation and maintenance market is "opening"

On August 20, 2021, with the authorization of GWO of Global Wind Energy Organization, the Beijing Check Heng Certification Center awarded GWO BR (Blade Repair Training) leaves for maintenance training service certification to the Zhuzhou Times New Material Technology Co., Ltd. (hereinafter referred to as the new material of the times). Certificate.

Times New Materials became the first and only wind power blades manufacturing enterprise at present in Asia.

In order to obtain certification, Times New Materials has established a special working group since January last year. With the overall planning of the college of the Times of China and the support of the wind power of CRRC Zhuzhou, the project team completed the 8 system documents of the system documents. Preparation and development of 22 leaves repair training courses (the cumulative course of the course is 4,200 minutes), the establishment of 2 practical training dojo (covering 74 equipment and facilities, seven major leaves repair activities), and 6 leave maintenance modules Internal training lecturer. In the end, professional censorship was passed and a certificate was obtained in one fell swoop.

Since the "Thirteenth Five -Year Plan", with the increase of the existing fans of the warranty, the wind power operation and maintenance market has gradually heated up. As of 2020, the number of domestic markets theoretically exceeds 80,000 fans and the capacity exceeds 140GW. Such a huge existing asset operation will inevitably produce huge and diversified operation and maintenance needs.

At present, the capacity of blades in the operation and maintenance market is uneven, and the risk of operation and maintenance has increased sharply for the owners. The weight.

Since 2021, Times New Materials Electricity Products Division has established a after -sales operation and maintenance business department to make the original market, technology, and service modules in deeper subdivision and expansion, and further improve the after -sales operation and maintenance capacity and quality of the leaves. One is one. In terms of independent establishment of internal blades operation and maintenance engineers, the skill grading training and certification system. On the one hand, actively participate in the GWO blade maintenance training service qualification certification of the global wind energy organization, in line with the international blade maintenance standards, and promote the establishment and defective maintenance of the domestic leave operation and maintenance industry standards Standardization and standardization.

At present, the operating and maintenance business sector of the new materials in the times uses regional management system operations. It has set up six leaves after sales service stations in South China, Central China, East China, Northwest, North China, and Northeast China. A number of services such as leaves maintenance, leaf technical reform, and leaf training consultation.

Taking the leaves of the blades as an example, the new material has established a comprehensive leaf damage grading standard, and based on the company's blade after -sales service informatization platform, the blade maintenance standardization process and blade maintenance database have been established to trace the maintenance data. Since 2009, more than 10,000 leaves have been completed in conventional maintenance, and hundreds of leaves have been technical maintenance. In terms of leaf technical reform, only 99 unavailability of ice blades (systems) had been installed from 2013 to 2020, and the output value exceeded 150 million yuan.

At present, relying on the production base of Zhuzhou, Hunan, the new materials of the times can carry out theoretical and practical training of wind power blades manufacturing and maintenance, so that students can master the blade inspection capabilities of the wind power generation unit, formulate maintenance plans, and implement maintenance work. Employees provide important training resources.
