  • Detail

How did Hunan's new installed capacity account for 1/10 of the country's total in 2016, where the advantage of wind resources is not prominent

Abstract: wind turbines should have their own characteristics. For example, in the central and southern regions, many provinces have the problem of freezing. The problem of freezing has a considerable impact on the operating efficiency and power generation of wind turbines. If the wind turbine manufacturers in Hunan can effectively solve this problem, it will not only promote the wind power development in Hunan, but also the wind power development in the whole central and southern regions, and even the wind power manufacturing industry in China

Hunan people who dare to be the first in the world have once again reached the forefront in the development of mountain wind power and low wind speed wind power. Hunan Province, which does not have outstanding advantages in wind resources, accounted for 1/10 of the country's new installed capacity in 2016

recently, at the Hunan wind power industry summit forum, one of the highlights of the industrial forum of the annual meeting of Chinese entrepreneurs, Liu Nianlai, deputy director of the Hunan Provincial Development and Reform Commission and director of the Hunan Provincial Energy Bureau, revealed that as a demonstration province for the development of mountain wind power in the central and western inland regions, as of the end of March this year, Hunan Province has completed a total investment of more than 20billion yuan in wind power construction, built 44 wind farms with a capacity of 2.25 million KW, and 50 wind power projects under construction With a capacity of 2.5 million KW, another approved project to be built and carry out preliminary work is about 5million kW

at present, wind power manufacturers represented by CRRC wind power, Xiangdian wind energy and Sany Heavy energy, wind power consulting and design institutions represented by Zhongnan survey and Design Institute and Hunan Electric Power Design Institute, wind power construction enterprises represented by Hunan thermal power and Hunan Construction Engineering, investors represented by Huadian, Huaneng and other power generation groups, and manufacturers of blades, substation equipment, wire and cable parts have initially formed, including design consulting The complete industrial system of wind power, including product research and development, equipment manufacturing, wind farm construction and power transmission, increasingly shows the clustering effect of wind power industry in Hunan

the industrial chain was basically formed.

ten years ago, the wt1650 wind turbine of CSR Zhuzhou Institute at that time was combined to generate power in Jianghua, Chenzhou, Hunan Province, announcing that Hunan Province has achieved a "zero" breakthrough in large-scale wind power generation; In 2009, Chenzhou yangtianhu wind farm, the first large-scale wind farm in Hunan Province, generated 33 units, creating a precedent for low wind speed wind power

in recent years, the installed capacity of wind power has grown from scratch, effectively adjusting the energy structure of Hunan Province. According to the data from Hunan Provincial Energy Bureau, the installed capacity of wind power accounted for 5.26% of the total installed capacity of Hunan Province in 2016, an increase of 5.13 percentage points over 2010. In 2016, wind power generation accounted for 2.95% of the power generation in Hunan Province, an increase of 2.92 percentage points over 2010. Jinan new era Gold Testing Instrument Co., Ltd. has studied various materials

Zhuzhou is an important industrial city in Hunan Province. This "city pulled by train" has an indissoluble bond with the railway. Nowadays, with the help of "high-speed rail technology", the wind power industry in Zhuzhou is in full swing

Yang Weiguo, deputy secretary of the Zhuzhou municipal Party committee and mayor of Zhuzhou, said that he insisted on market guidance and innovation drive, and constantly improved the technological innovation system with enterprises as the main body, market orientation and the combination of industry, University and research. In recent years, Zhuzhou has focused on cultivating and supporting a number of wind power enterprises with industry leading advantages, forming wind power blades, converters, generators with "high-speed rail gene" represented by CRRC Zhuzhou Institute A relatively complete wind power industry cluster dominated by gear boxes and other parts. In 2016, Zhuzhou wind power industry achieved sales revenue of nearly 10billion yuan. In the next stage, we will build "Zhuzhou ˙ China Power Valley ", accelerate the construction of new energy development strategic alliance represented by wind power industry, strive to enhance the core competitiveness of wind power enterprises, and effectively promote the healthy and rapid development of wind power industry

Liu Nianlai believes that relying on the rapid development of wind power industry, Hunan has also made breakthroughs in wind power technology research and development. CRRC Zhuzhou Institute transplanted the mature R & D experience accumulated in rail transit to wind turbine products, and has a strong competitive advantage in the high altitude and low wind speed markets; Xiangdian wind energy has national R & D platforms such as the national wind power R & D (experimental) center; Sany can propose an intelligent control solution for large blades with low wind speed; Zhuzhou Shidai new material (12.300, 0.03, 0.24%) has strong technical advantages in blade design, molding process, process equipment and material technology research and development; The Central South Survey and Design Institute and Hunan Electric Power Design Institute have made a lot of achievements in the planning, design, general contracting, construction and operation of the southern land ultra-low speed mountain wind power project; Central South University and Xiangnan University have successively undertaken a number of wind power industry, University and research projects The working environment for placing instruments should be kept clean, and a number of technologies with independent intellectual property rights have been applied to wind power equipment

explore experience and explore Hunan path

Chen Yuehui, deputy chief engineer of Hunan electric power company, revealed that in 2016, Hunan's cumulative wind power generation was 3.93 billion hours, an increase of 76.45% over 2015; The utilization hours of equipment were 2124 hours, an increase of 0.46% over 2015. At present, the maximum output of wind power is 1.6 million kW (19:09 on February 19, 2017); Wind power output accounts for the daily power generation load. It is recommended that export enterprises build a safety assurance system focusing on "raw material procurement - raw material account management - factory safety and health control". The maximum proportion is 15.07% (0:00 on February 27, 2017)

thanks to the progress of low wind speed technology, Hunan, which used to require different fixtures for different materials, has seen its exploitable wind power leap to more than 20million kW, which means that more than 80% of the wind power resources have yet to be developed

the terrain of Hunan is high in the West and low in the East, high in the South and low in the north, covering three types of wind power: mountain wind power, hill wind power and plain wind power. Generally speaking, it belongs to the region with low wind speed. Mountain wind power has low wind speed, multi wind direction, large turbulence, large defecation, many disasters, complex terrain and geology, so the cost is relatively high. Hu Jie, vice president of Sany Heavy Energy Research Institute, believes that in Hunan region, if we want to achieve a yield of 10%, the effective hours of fan utilization should reach more than 1750 hours; If you want to achieve a yield of 14% and 15%, the effective hours of fan utilization must reach more than 1900 hours

liuxiaosong, President of New Energy Institute of Central South Survey, design and Research Institute, told that Hunan wind power is mainly mountainous, which puts forward higher requirements for the design of wind farms and complete machines. Long blades and high towers are relatively direct ways to increase the power generation of low wind speed wind farms, but more importantly, the performance of fans as a whole should be improved by improving the self-learning ability of fans and optimizing the intelligent control system of fans

Zhou Sheng, general manager of new energy company of Hunan Electric Power Design Institute, believes that most of the current wind turbine layout schemes consider the optimal power generation, and less consider the overall economy in combination with the construction conditions. For low wind speed wind power, we should adopt the way of professional collaboration and professional integration, integrate electrical, civil and other links, and fully consider and repeatedly study the construction costs and benefits when optimizing the wind turbine layout plan, so as to ensure the overall economy of the whole wind farm is optimal

sharpen your knife without mistaking the firewood cutter. Liu Xiaosong believes that the terrain of wind power in mountainous areas is complex and changeable. It is recommended to arrange at least two wind measuring towers in a wind farm area, and the observation period should not be less than 1 complete year. Sufficient wind measurement in the early stage is conducive to achieving the expected return on investment of the project

Wang Di, deputy director of CRRC wind power technology center, revealed that low wind speed wind power in mountainous areas puts forward higher requirements for wind resource analysis. Based on this, CRRC Zhuzhou Institute cooperates with the National Climate Center and France medico to integrate the world's most advanced wind resource technology and experience to build a wind resource system platform, which is expected to be open for public beta in June this year

Liu Nianlai said that in recent years, the rapid development of low wind speed wind farms in mountainous areas in Hunan Province is a vivid interpretation of wind power technology innovation. In the future, sustainable innovation should be achieved in development mode, technical reserves, comprehensive skills, delivery and consumption, etc

"low wind energy resources are more dispersed, and large-scale centralized and continuous development will be unsustainable. Decentralized development, nearby access and local consumption will be more feasible, and decentralized wind power will be the development trend." Liu Nian said, "mountain wind farms are doomed to the complexity of the site topography. Wind turbine enterprises and design institutes should focus on the research of overall solutions, realize the transformation from selling equipment to selling services, from single supply to comprehensive disposal, and comprehensively improve the comprehensive technical level."

long Yunhan, director of Shenhua new energy central China regional preparation office, said in an interview that Shenhua is very optimistic about the low wind speed wind power market in central and southern China, and will work with CRRC Zhuzhou Institute, which has geographical and technological advantages, to develop about 3million kW wind power projects in the next three years

Hunan wind turbine manufacturing should adapt to local conditions

"the development of low wind speed wind power has led to the increase of blades, towers and installation difficulties. Under this condition, the price of wind power is still declining due to fierce market competition and developer pressure. This is detrimental to the scientific and technological innovation and sustainable development of the entire wind power manufacturing industry." Qi Hesheng, Secretary General of the wind energy equipment branch of the China Agricultural Machinery Industry Association, said, "on the one hand, it is under the pressure of developers, on the other hand, it is squeezed by parts suppliers. The unit kilowatt price of wind turbine has fallen from 12000 yuan in 2000 to less than 4000 yuan now."

in the view of Li Junfeng, former director of the National Center for strategic research and international cooperation on climate change, compared with the photovoltaic industry, China's wind power industry has not reached the level of the global technology research and development and scientific and technological service teams operate around the Chinese market and industrial chain. He believes that the wind power manufacturing industry should learn from the accumulated experience of the rail transit industry and put quality, stability and reliability at a higher position

Liu Xiaosong suggested that the manufacturing of complete wind turbines must be adapted to local conditions and developed differently. "Wind turbines should have their own characteristics. For example, in the central and southern regions, many provinces have freezing problems. The freezing problem has a considerable impact on the operating efficiency and power generation of wind turbines. If the wind turbine manufacturers in Hunan can effectively solve this problem, it will not only promote the wind power in Hunan, but also the wind power development in the whole central and southern regions, and even the wind power manufacturing industry in the country." Liu Xiaosong said

"CRRC is promoting the 1+n+1 industrial development strategy, in which the wind power industry is built as the second pillar industry besides rail transit. A relatively complete industrial chain represented by the wind power complete machine and wind power blades of CRRC Zhuzhou Institute has been formed in Zhuzhou City. According to the planning goal, the annual sales revenue of CRRC wind power complete machine will exceed 10billion yuan by 2020." Fan Baolin, deputy general manager of CRRC Zhuzhou Institute, said, "at present, the lowest wind speed that can be economically developed is 5 meters/second. With the release of new units, 4.8 meters/second wind resources will also have economic development value."
