With the 20,000th blower, the Vestas 2 MW platform achieved a new milestone.
Seventeen years after its launch, as Vestas installed the 20,000th 2 MW platform fan, the 2 MW platform reached another milestone, firmly establishing itself as one of the most widely used wind turbines in the world. Sri Lanka continues to innovate and optimize the strength of 2 MW platform stand-alone annual power generation has been promoted by 40%, 17 years has always been at the forefront of the market.
Milestone 20,000 units
Today, 2 MW platforms with a total installed capacity of 38 GW are distributed in 45 countries on six continents. "20,000 turbines with the same platform installed in 45 countries on six continents are a worthy example for Vestas Proud achievements demonstrate our ability to be at the forefront of the market through continuous product innovation and reduced power generation costs, "said Anders Vedel, Vestas' executive vice president, CTO." Thanks to proven technology, the 2 MW platform Five models provide outstanding performance and reliability, while retaining the same cabin size and lightweight design, to ensure that its transport and installation process of predictability.
This groundbreaking installation took place at the site of the 2 GW Wind XI project in Iowa, USA, with a capacity of V110-2.0 MW. The developer of this project is a subsidiary of Berkshire Hathaway Energy, Sino-American Energy Corp. .
The Wind XI project reflects the platform's flexibility in the U.S. market, with the 2 MW platform accounting for 12% of the U.S. market and 8% of the global market. * The United States is the world's second largest wind power market Vestas 2 MW platform reached 10GW in the United States, about one-quarter of the global installed capacity of the 2 MW platform.
Chris Brown, Vestas' president of sales and services in the United States and Canada, added that the '2 MW platform was instrumental in Vestas' success in the United States by giving its customers full product and technical value. We are very proud to have achieved this milestone in the United States by improving the platform and making it thrive. "
The 2 MW platform has been upgraded to the new V120-2.0 / 2.2 MW this year, starting with the V80-2.0 MW model introduced in 2000. Below is a blockbuster advertisement of 2 MW fans installed over 18,000 units worldwide.
Force China low wind speed
Most importantly (knock blackboard): The latest V120-2.2 MW is Vestas models tailored to China's low-wind market, mainly reflected in:
1. Larger impeller diameter
It is a well-known fact that the challenge for OEMs at low wind speeds is clear: how to capture more energy from fainter winds? The most immediate solution is to increase the unit of air swept area by lengthening the blades V120-2.0 / 2.2 MW Based on structural shell technology and excellent load balancing, a new vane length of 59 meters optimizes aerodynamic performance while maintaining light weight and matching existing engine room and wheel hub dimensions. With the V110-2.0 / 2.2 MW fan phase The V120-2.0 / 2.2 MW root diameter remains unchanged at 1.8 meters and the swept area increases by 19%, representing a 19% increase in the ability to capture wind with the following benefits: With V110-2.0 / 2.2 MW Compared to V120-2.0 / 2.2 MW models, the maximum power output can be increased by 13%.
Better load control
Although the increase of the diameter of the impeller contributes to the improvement of the swept wind area per kilowatt, it also brings the weight of the blade and the increase of the whole machine load, and the requirements of the whole machine are also stricter.In general, the efficiency of the load control is directly Reflected in the weight of the various components such as leaves and tower tube.Only by controlling the load and reduce the load on these key components, these components have the optimal space.If you can not control the blade weight, blindly increase the blade length, Although on the surface it seems that the unit of kilowatt swept wind area is increased, but it will cause instability of the overall performance of the unit over time will appear a variety of failures, the so-called desire 'long' is not up to .From the fan's full life Cycle, through the stable and reliable performance to achieve the lowest cost of electricity throughout the life cycle is the customer's most concerned about.
Vestas knows this very well, so while increasing the swept area by 19%, effectively controlling the weight of the blade increases only by 8% and the weight of a single blade is only about 8.7 tons, with a clear weight advantage In addition, V120-2.0 / 2.2 MW can be flexible tower design up to 141 meters depending on the project, while its weight is controlled at only 279 tons.Lightweight blades and towers not only control the cost increases and the whole machine Load, more to ensure that units as always, the stability of performance.
3. Higher component strength
Blade lengthened models still have a stable and reliable control through rigorous component upgrades to enhance the strength of the 120-meter diameter wind wheel completely match the platform design parameters and carrying capacity to ensure the operation of large wind wheel control is stable and reliable. , The bearing capacity of blade root roller bearings is increased by 25%, the blade pitch hydraulic drive capacity is improved by 25%, and the wheel hubs are reinforced.
Johnny Thomsen, Vestas senior vice president and head of product management, said at the press conference: 'The Chinese market is one of Vestas' strategic priorities. Since entering China in 1986, With its rooted roots in China, Tasas brings new products to the market. The introduction of the latest V120-2.0 / 2.2 MW models reflects Vestas 'long-term commitment to the Chinese market.'
