In the digital wind power era curtain opening, has been leading the wind power digital trend of energy on October 17 in 2017 Beijing International Wind Energy Conference and Exhibition during the official release of three intelligent fan models: land EN-131 / 2.5MW, EN-140 / 3.0MW and sea EN-148 / 4.5MW.

In the vision, digitalization is not just the fancy concept, but the real application of large data, cloud computing and intelligent technology to help wind power industry to solve the ills, to help the industry to seek lower cost of electricity, better solutions. Deputy General Manager Dr. Wang Xiaoyu said, 'At present, intelligent fans have become the standard of wind power industry.'
According to the introduction, the land-based EN-131 / 2.5 MW model based on AWS cloud platform computing power and DOE optimization algorithm to achieve the overall optimization of the blade and more target optimization, to achieve a high efficiency, low load optimal wing. Through the use of advanced and mature large-speed ratio of large torque gear box technology, both to enhance the conversion efficiency of electricity, but also reduces the noise of the wind turbine, the average wind speed of 5m / s wind resource scenarios can be achieved more than 2000h annual use The number of hours, is the first at home and abroad can be dropping to low wind speed range of 2.5MW stand-alone capacity unit.
Land EN-140 / 3.0MW models, with the vision two years ago in the Danish national test wind farm operation and get DNVGL complete type certification EN-120 / 3.0MW models from the same platform, adhering to the former excellent performance European gene, the highest unit power output, the modular upgrade after the replacement rate of more than 95%, cabin size is small, light weight, cabin and tower can be completely used 2.XMW platform models of transport and lifting programs, more Lightweight steel cone and basic design to the wind field to bring lower unit kilowatt cost. Large megawatt, low wind speed, low noise level so that this fan for the decentralized wind power development to solve the capacity shortage, the unit kilowatt investment The challenge for the development of decentralized wind power into a solid foundation.
For the development of terrestrial wind power prospects, vision energy vice president Tian Qingjun that the next industry 'outlet' will be decentralized wind power.He said that at present, distributed photovoltaic and household photovoltaic development is relatively rapid, it is because of its concern users, So that end users can really benefit from the development of the industry.Transclusive wind power will be a future period of China's wind power industry development important direction to discuss the development of decentralized wind power can not be confined to the wind power industry, must be to the photovoltaic industry as much To pay attention to the interests of end users.
First, the decentralized wind power development model needs to be diversified, it is possible that the current situation is that the current concentration of wind power developers is no longer the main force of decentralized wind power development.Finally, whether centralized or decentralized, only So that the wind power costs down to a low enough to mobilize the enthusiasm of developers.Third, the land is relatively easy to obtain and the power grid support capacity is relatively good in the vast rural areas will become the main battlefield of decentralized wind power.
The EN-148 / 4.5MW offshore model is based on EN-136 / 4.2MW mature models 4 years of experience in the operation of the sea to optimize the upgrade, specifically for China's coastal wind speed is low, typhoons and the characteristics of complex geological design , Has adopted a well-tested topology logic and supply chain system in European offshore wind power, with greater resistance to typhoon performance, higher reliability and power generation, and lower cost of electricity. It is worth mentioning that, due to The introduction of DFX virtualization design, the use of 3D digital prototyping coupled synchronization project, the development of new tooling can be no large-scale crane in the scene, to achieve the leaves, gear boxes, generators replacement, can greatly reduce the cost of sea operation and maintenance The
In view of the demand trend of offshore wind power market, Dr. Wang Xiaoyu said: 'can not simply say that large capacity units or small capacity units is good, regardless of unit size, lower cost of electricity is king.
'Vision in the carbon fiber leaves and many other areas boldly lead the wind power technology innovation, but the technological innovation and prudent industrialization is not contradictory.Watch than any wind power manufacturing enterprises are daring to innovate, but in the process of innovation and technology industrialization than other enterprises Are more cautious. "Dr. Wang Xiaoyu said, 'Vision' s goal is to low cost of electricity, high reliability, for the industry needs to provide cost and efficiency of the best integrated solution, not superstitious any kind of technical line.
