Mobile WebSiteWind, water from; wind, surging. If the interpretation of the massive in recent years, thriving wind power industry, this group of words can be described as image. From the land and sea, from high altitude to low wind speed, among the third largest power supply wind power carried by the new energy banner, is the wind breeze, rustling.
Data as evidence. According to the "wind power development" thirteen five "plan" shows, "second five" period, China's wind power installed capacity for five consecutive years leading the world, the cumulative new 98 million kilowatts, accounting for the same period the country's total installed capacity of 18% , The proportion in the power structure increased year by year.
So, from the ocean to the Gobi, white winds mushroomed, towering stands. The fan under the most solid foundation, is a wind power technology breakthrough and innovation, it is they, confirming the pursuit of "wind" who wind and the wind, the wind and dance track.
"Nuggets" Blue Ocean
Compared with the terrestrial wind power, offshore wind power has excellent wind conditions, the average annual use of high hours, do not take up land resources, from the power load center and other advantages.
However, large-scale offshore wind power grid is facing many challenges. For example, the offshore wind farm booster stations and wind turbines are located in the sea, its operation and maintenance is more difficult than the land wind farm, the offshore wind power highly reliable integrated design technology, forecasting technology and remote cluster control technology are put forward New requirements.
In order to support the large-scale development of offshore wind power in China, "Twelfth Five-Year Plan" period, 863 plan advanced energy technology specifically for this deployment
In the process of research, the research on the characteristics of wind / DC grid connection and the operation control and protection of offshore wind power is carried out. The operational control strategy of reactive power configuration scheme, fault crossing technology scheme and dynamic voltage coordination control strategy of offshore wind farm is put forward. The submarine cable overvoltage and protection test platform for offshore wind farm collection and delivery systems can be applied to submarine cable tests at 500 kV and below. The offshore wind power collection system / substation high reliability optimization design and Integrated technology program, into the national energy industry standard "wind farm project 110 ~ 220 kV sea substation substation design specifications"
"This topic is based on the development of offshore wind power in China and the urgent problems to be solved, and the offshore wind farm near the load center as the research object, the relevant experimental platform construction and system research and development, and to achieve demonstration applications, improve China's offshore wind energy Resource development of the technical level. "The industry concluded that.
Research on Focused Wind Power Transmission and Control
In order to form a leading product and core technology with independent intellectual property rights, in December 2011, the Ministry of Science and Technology approved the project, the formation of "national wind power transmission and control engineering technology research center."
After four years of construction, February 23, 2016, the Ministry of Science and Technology on the center of the acceptance. 4 years, the center focused on wind power transmission and control areas, carried out the wind power transmission, control, manufacturing, testing and other key core technology research, the establishment of the 10 design and research (the), three laboratories and an overseas R & D center , Commitment to the national, provincial science and technology project project 4, completed 14 related research topics.
In the process, the center formed a wind power gear box lightweight design, intelligent transmission and control and other common technology, independent development of the 6 MW wind turbine gearbox, yaw pitch drive, electronic control system, lubrication system with international Advanced level of wind power new products, to fill the gaps, and to achieve the wind power design and manufacturing technology and system control technology results transformation and application for China's wind power technology and industrial development has made contributions.
Force distributed medium and small wind power
According to the application of foreign small and medium-sized wind power to promote the experience of small and medium-sized wind turbine directly connected to power generation is economical and reliable. Compared to large-scale wind power, the domestic small and medium-sized wind power market has yet to be pioneered, "second five" national science and technology support project "distributed small and medium-sized wind turbine design and manufacture of key technologies" or can help break the board.
On June 24, 2015, the project passed the acceptance in Beijing. This paper studies the adjustment method of blade mechanical pneumatic pitch power, wind wheel umbrella power, wind turbine active side side power and blade centrifugal passive pitch power, etc., in view of the low temperature and wind in northern China accompanied by dust storms Environmental and the coastal climate of the southeastern coastal typhoon-prone areas, developed a wind-driven pneumatic pneumatic pitch-type 5-kilowatt wind turbine, active side-side 20-kilowatt wind turbine and low-range centrifugal passive variable pitch 50-kilowatt wind turbine Carried out on-site operation and testing.
In addition, the project developed in line with China's climate characteristics of small and medium-sized wind turbine test system, built small and medium-sized wind turbine coastal and northern test stations, and complete 1.5 to 100 kilowatts related test and certification work.
The project leader said that the implementation of the project to improve China's small and medium-sized wind turbines in China's north-south climate environment adaptability, durability and reliability, to promote the development of China's distributed small and medium-sized wind power has a positive significance.
