In the realm of renewable energy, a significant development has recently transpired. Shanghai Electric Wind Power Group, the esteemed subsidiary of Shanghai Electric (SEHK:2727, SSE:601727), has marked the fifth anniversary of its European Innovation Center ("the Center") in Rosklide, Denmark. This company, renowned for its commitment to clean energy equipment, has consistently been a trailblazer in the wind energy sector.
The Center recently hosted the 5th International Symposium on Leading Edge Erosion of Wind Turbine Blades, an event that brought together the brightest minds in wind energy technology. Among the luminaries was Koji Fukami, a Senior Blade Design Expert, who presented his groundbreaking research titled "Engineering Estimation of Severe Leading Edge Roughness Effect."
Fukami articulated the urgent need to establish a connection between academia and the wind energy industry. The objective is to find more pragmatic, time-efficient, and cost-effective methods to assess and optimize blade designs, especially under harsh conditions.
His study, conducted in collaboration with the Center, introduced a novel approach to estimating the impact of leading-edge roughness on wind turbine blades in high precipitation environments, both offshore and onshore.
The importance of wind turbine blades in wind power generation cannot be overstated. Their integrity directly affects the system's productivity. Erosion, primarily due to wind force, is a common problem. Rain erosion is acknowledged as the chief culprit behind damage to the blades' leading edges.
It's a battle where the elements meet technology. Megawatt-class blades operate at tip speeds exceeding 90m/s. At these speeds, raindrops can hit with force akin to bullets, causing substantial tearing forces. This repetitive impact leads to fatigue processes, resulting in the protective layer's damage, ultimately compromising the entire leading-edge protective structure.
In designing blades and airfoils for real-world operation, it is imperative to address the influence of severe environmental conditions for robust performance. The new approach presented enables precise simulation for blade design with a reduction in computational demand, making the design process faster, less costly, and more functional.
This method employs concepts from unsteady aerodynamics to optimize airfoil designs. It draws on simulation results that reflect real operational conditions. The high degree of alignment between the simulation data from this method and the experimental data publicly released by the University of Illinois indicates a strong match between the two datasets.
This coming November, the Center will embark on a new round of collaboration with the Technical University of Denmark. The focus will be on wind tunnel experiments to test the performance of new airfoil designs and evaluate new simulation methods.
The Center, founded in March 2019, has capitalized on Denmark's strategic strengths in the wind energy sector. This approach has attracted a multitude of elite engineering specialists to the Center.
The Center has rapidly evolved from a startup in a single office to a modern science and innovation center with a significant employee base. It has achieved numerous successes in technology innovation projects and acquired many patents.
These advancements are being progressively utilized to empower advancements in control algorithms, load analysis, blade design, and the optimization of wind farms. The center’s work has undoubtedly brought a new dawn in the field of wind energy technology.
In closing, the path-breaking work led by Koji Fukami and his team at Shanghai Electric Wind Power Group's European Innovation Center is indeed a giant leap for the wind energy sector. As they continue to innovate and revolutionize, the future of wind energy looks promising, more efficient, and more sustainable.
