Aerodynamic Upgrade Solutions for Optimization of Wind Turbines
Our solutions are developed to ensure that you don't have to settle for less than maximum performance.
The dominant noise source from a wind turbine comes from the blades’ passage through the air. Depending on local regulations and proximity of turbines to housing, it may be necessary to reduce the noise from the wind turbine. PowerCurve's noise reduction solutions can be deployed to ensure turbines can produce their expected AEP, free from curtailment.
As turbines have increased in size, noise has also increased due to higher tip speeds. A typical mitigation approach to this problem is to run the turbine in a low noise mode, which often means curtailing energy production. By installing PowerCurve’s noise reduction solutions the problem is addressed at its source – the aerofoils - allowing turbines to escape noise reduced operation modes and restore AEP.
Wind turbine size and noise emissions grow while wind parks and civilization move closer.
Regulatory requirements for noise levels can force turbines into curtailment mode. With PowerCurve’s solution for noise reduction we help you stay compliant with noise regulations without compromising annual energy production.
Our new noise reduction solution is developed with an optimized and revolutionary shape. It is applied to the trailing edge of the blade and works by breaking up the turbulent airflow that normally forms behind the blade. Instead of creating one large area of noisy turbulence, serrations spread the airflow into smaller, less loud swirls – which reduces the sound that’s produced. This helps lower overall noise levels without curtailing the turbine.
It is critical that any blade upgrade solution does not have a damaging impact on any turbine components. Our design process is engineering-driven to deliver products that are load-neutral for the entire turbine.
Our noise reduction solution is compatible with most of existing blade add-ons and can be combined with new installations.
Our noise reduction solution is designed for fast and easy installation. It can be fitted directly onto the blade without having it on ground, which means there’s no need for cranes or major downtime. The upgrade is typically done during scheduled maintenance or alongside other blade improvements like LEP or vortex generators. This makes it a low-disruption solution that saves time, reduces costs, and keeps your turbines running.
