2017 Beijing International Wind Energy Conference and Exhibition last week came to an end.As a window to observe the development trend of wind power industry, CWP2017 also shows the wind power technology and the future direction of market development.
If the 10 years for the sector, Beijing Wind Energy Conference with China's wind power industry has gone through the rapid development of 10 years, standing at a new starting point of China's wind power industry has shown what new changes, new trends?
The larger blades are longer
This year's show, a number of machine business to bring a larger capacity wind turbine unit. China Sea pushed 5 MW level of the world's largest wind wheel diameter H171 unit; Mingyang launched semi-direct drive MYSE3.2-145 and MYSE5. 5-155 big fan.
In particular, it is worth mentioning that, in the current land is still 2MW and 2.5MW fan accounted for the mainstream of the case, the wind technology is the first to launch the first domestic 4MW level models. At the same time launched for the sea GW6.X platform.
Industry Analysis:
On the one hand, the use of large capacity models, which can effectively reduce the number of units installed to save the project pre-investment costs;
On the other hand, the reduction in the number of units can help optimize the design of wind farms, so that in different projects, a significant reduction in the impact of the wake, effectively improve the overall power generation capacity of wind farms.
In contrast, the new models brought by multinational giants did not increase the capacity of the machine in the stand-alone capacity, but is reflected in the lengthening of the leaf and the increase of the unit kilowatt sweep area, such as Vestas Launched the V120-2.0 / 2.2MW, Siemens - Gemei Sa launched G122-2.1MW models, more emphasis on emphasizing the optimized power curve, higher capacity factor.
According to Luoyang Shuangrui Wind Power Blade Co., Ltd. Vice Minister of Research and Development Wu Shengjun introduced, since 2007, the wind turbine rotor diameter from the previous 82 meters to enhance the diameter of the fan is still increasing. To the present 180 meters, more than doubled.
The manufacturer is transitioning to the service provider
The show is a highlight of the machine is not only show the whole product, but its entire solution and services.This shows that the competition in the wind power market has entered a new stage. To provide fan products, but also to provide from the previous wind, micro site selection to the latter part of a full set of operation and maintenance solutions.This is the wind power market, with the trend of bidding procedures.
With the rise of low wind speed wind power development, low wind speed development is often accompanied by complex terrain, which makes the 'good wind field is designed' concept enjoys popular support. This requires local conditions, based on the target wind farm unit load, environmental adaptability , The customization of parts and components; from the wind and weather to the air, the unit, the wind field of custom construction and operation and maintenance. Based on this, the whole machine business service competition is becoming increasingly fierce.
It is also in this context that China Sea has launched its LiGa Wind Energy Resource Assessment System at the show, which is designed to provide customers with 'wind farm planning, wind planning, wind resource assessment, Site selection, wind power forecast 'and other services.
In the exhibition, Zhuzhou is fully engaged with the National Climate Center and the French company in the United States and Germany in-depth cooperation, the use of vehicles in the large data, cloud computing, high-performance computing The purpose of wind power operators to provide wind power plant investment and operation of key technology solutions to provide risk of pre-control, reduce the future of wind farm capacity assessment uncertainty, to achieve wind farm design Solution optimization.
At present, in Vestas, Siemens - Gemei Sa and other international giants of the business structure, the operation and maintenance services for its return or even catch up with the machine equipment sales return, which also reflects the machine business future The development trend.
China in the car booth collection of Zhuzhou, Yongji Electric, Zhuzhou Motor and other vehicle system in a number of wind power industry chain enterprises. China Shipbuilding Industry booth also set up the Chinese sea, heavy teeth and many other heavy shipbuilding system Machine and supporting enterprises.The two machine manufacturers with central enterprises background, are strongly recommend their own industry chain to prove their own capacity in the wind power services, but how to industrial chain advantage into real strength, remains to be excavated and Integration.
Digital crack industry pain points
Digital and intelligent is not a new concept, but never as close as today with the wind power industry, as Dr. Wang Xiaoyu, vice president of vision energy, said, "After seven years of development, smart fans have become the standard for the wind power industry.
With the rapid development of wind power in China, the number of fans has increased dramatically. In the face of the huge stock market and the foreseeable incremental market, digital technology, represented by artificial intelligence, large data and cloud computing, will play more and more in the market after wind power UP-WindEYE, an intelligent wind farm service system for the operation and maintenance market, provides the wisdom of the wind farm through high-speed interconnection, power grid support, energy management, station scheduling automation, panoramic monitoring, health assessment and other functions. Comprehensive solution.
In addition to intelligent wind turbines, the wind field digital operation has become the industry consensus, the data is the basis of all the many centralized control center is the most troublesome problem is that the function is achieved, the data is never quasi-wind farm operation is the core of the loss of power. New energy power plant to calculate the loss of electricity is not rigorous way, there are a lot of manual statistics, environmental changes and equipment itself to bring the error.
Vision energy intelligence wind field software person in charge of Zhao Qingsheng introduction, 'small power station to the grassroots level of the staff of the bonus income, large to the National Energy Board on the abandoned power of the discarded rate of' double abandonment 'assessment, because the loss of electricity can not be accurate statistics Is affected. 'For these troubled industry problems, the prospect of energy through EnOS wisdom wind field software to solve the problem.
In addition to the whole machine, as a component supplier, the South High Teams Group launched the 'information gearbox', and demonstrated based on the Internet of things, large data and cloud computing to establish the wind power information gearbox life cycle management system , Aimed at promoting the intelligent development of wind power industry.
After years of development, digital for the wind power industry, is not a fancy concept, but to really solve the industry pain points to help enhance the efficiency of wind farms, reducing the cost of life cycle.
