Recently, Vision Energy Research and Development's first 120-meter all-steel flexible tower EN121-2.2MW unit was awarded the first 120-meter-tall tower unit type A certification issued by the authoritative certification body.
How to ensure the profitability of low wind speed wind farm projects has become the focus and technical difficulties of the industry. As a pioneer and technology leader in low wind speed intelligent wind turbines, Vision Energy continues to lead the way in low wind speed technology. The successful application of flexible high-towers has once again demonstrated the industry leading position of Vision Intelligent Fan Technology.
Dr. Wang Xiaoyu, deputy general manager of Vision Energy, said that taking the shear factor of wind resources as 0.3 as an example, compared with the height of the traditional tower of 90 meters, the 120-meter all-steel flexible tower unit of Vision Energy can increase the power generation income by more than 300 hours per year. This means that there are more ultra-low wind speed areas with development possibilities and higher economics. He also said that the vision can make the 120-meter all-steel tower a cost-competitive advantage without losing power generation, thanks to the advanced algorithm technology of the vision intelligent fan control platform 2.0. Fortunately, the 120-meter-tall tower technology also has potential for development in high-shear areas with a height of 4.8 m/s at 80 m.
The relevant person in charge of the Certification and Certification Center stated that the first type A certification issued for the vision EN121-2.2MW 120-meter high tower unit was input with a 120-meter all-steel flexible tower as the design model, and the whole machine was carried out in accordance with IEC standards. The whole case simulation, at the same time assisted in the field high-tower machine frequency and other related tests, the post-processing results of the test data show that the prototype and the design goal are perfectly matched, the design and performance of the whole machine are fully verified, and the high tower tube machine is further proved. Safety and reliability. The person in charge said that he hopes that more technological innovations will accelerate the progress of China's wind power technology through the test of practice and certification.
